MATERNAL/OB NOTES

Human Sexuality
A. Concepts
1. A person’s sexuality encompasses the complex behaviors, attitudes emotions and preferences that are related to sexual self and eroticism.
2. Sex – basic and dynamic aspect of life
3. During reproductive years, the nurse performs as resource person on human sexuality.
B. Definitions related to sexuality:

Gender identity – sense of femininity or masculinity
2-4 yrs/3 yrs gender identity develops.
Role identity – attitudes, behaviors and attributes that differentiate roles

Sex – biologic male or female status. Sometimes referred to a specific sexual behavior such as sexual intercourse.

Sexuality - behavior of being boy or girl, male or female man/ woman. Entity life long dynamic change.
- developed at the moment of conception.

II. Sexual Anatomy and Physiology
A. Female Reproductive System
1. External value or pretender
a. Mons pubis/veneris - a pad of fatty tissues that lies over the symphysis pubis covered by skin and at puberty covered by pubic hair that serves as cushion or protection to the symphysis pubis.

Stages of Pubic Hair Development
Tannerscale tool - used to determine sexual maturity rating.
Stage 1 – Pre-adolescence. No pubic hair. Fine body hair only
Stage 2 – Occurs between ages 11 and 12 – sparse, long, slightly pigmented & curly hair at pubis symphysis
Stage 3 occurs between ages 12 and 13 – darker & curlier at labia
Stage 4 – occurs between ages 13 and 14, hair assumes the normal appearance of an adult but is not so thick and does no appear to the inner aspect of the upper thigh.
Stage 5 sexual maturity- normal adult- appear inner aspect of upper thigh .
b. Labia Majora - large lips longitudinal fold, extends symphisis pubis to perineum
c. Labia Minora – 2 sensitive structures
clitoris- anterior, pea shaped erectile tissue with lots sensitive nerve endings sight of sexual arousal (Greek-key)

fourchette- Posterior, tapers posteriorly of the labia minora- sensitive to manipulation, torn during delivery.
Site – episiotomy.

d. Vestibule – an almond shaped area that contains the hymen, vaginal orifice and bartholene’s glands.

1. Urinary Meatus – small opening of urethra, serves for urination
2. Skenes glands/or paraurethral gland – mucus secreting subs for lubrication
3. hymen – covers vaginal orifice, membranous tissue
4. vaginal orifice – external opening of vagina
5. bartholene’s glands- paravaginal gland or vulvo vaginal gland -2 small mucus secreting subs – secrets alkaline subs.
Alkaline – neutralizes acidity of vagina
Ph of vagina - acidic
Doderleins bacillus – responsible for acidity of vagina
Carumculae mystiformes-healing of torn hymen
e. Perineum – muscular structure – loc – lower vagina & anus
Internal:
A. vagina – female organ of copulation, passageway of mens & fetus, 3 – 4inches or 8 – 10 cm long, dilated canal
Rugae – permits stretching without tearing

B. uterus- Organ of mens is a hollow, thick walled muscular organ. It varies in size, shape and weights.
Size- 1x2x3
Shape: nonpregnant pear shaped / pregnant - ovoid
Weight - nonpregnant – 50 -60 kg- pregnant – 1,000g
Pregnant/ Involution of uterus:
4th stage of labor - 1000g
2 weeks after delivery - 500g
3 weeks after delivery - 300 g
5-6 weeks after delivery - returns to original, state 50 – 60

Three parts of the uterus
1. fundus - upper cylindrical layer
2. corpus/body - upper triangular layer
3. cervix - lower cylindrical layer
* Isthmus lower uterine segment during pregnancy
Cornua-junction between fundus & interstitial
Muscular compositions: there are three main muscle layers which make expansion possible in every direction.
1. Endometrium- inside uterus, lines the nonpregnant uterus. Muscle layer for menstruation. Sloughs during menstruation.
Decidua- thick layer.
Endometriosis-proliferation of endometrial lining outside uterus. Common site: ovary.
S/sx: dysmennorhea, low back pain.
Dx: biopsy, laparoscopy
Meds: 1. Danazole (Danocrene) a. to stop mens b. inhibit ovulation
2. Lupreulide (Lupron) –inhibit FSH/LH production
2. Myometrium – largest part of the uterus, muscle layer for delivery process
Its smooth muscles are considered to be the living ligature of the body.
- Power of labor, resp- contraction of the uterus
3. Perimetrium – protects entire uterus

C. ovaries – 2 female sex glands, almond shaped. Ext- vestibule int – ovaries
Function: 1. ovulation
2. Production of hormones

d. Fallopian tubes – 2-3 inches long that serves as a passageway of the sperm from the uterus to the ampulla or the passageway of the mature ovum or fertilized ovum from the ampulla to the uterus.

4 significant segments
1. Infundibulum – distal part of FT, trumpet or funnel shaped, swollen at ovulation
2. Ampulla – outer 3rd or 2nd half, site of fertilization
3. Isthmus – site of sterilization – bilateral tubal ligation
4. Interstitial – site of ectopic pregnancy – most dangerous

B. Male Reproductive System
1. External
penis – the male organ of copulation and urination. It contains of a body of a shaft consisting of 3 cylindrical layers and erectile tissues. At its tip is the most sensitive area comparable to that of the clitoris in the female – the glands penis.

3 Cylindrical Layers
2 corpora cavernosa
1 corpus spongiosum

Scrotum – a pouch hanging below the pendulous penis, with a medial septum dividing into two sacs, each of which contains a testes.
cooling mechanism of testes
- < 2 degrees C than body temp.
- Leydig cell – release testosterone









2. Internal

The Process of Spermatogenesis – maturation of sperm







Male and Female homologues

Male Female
Penile glans Clitoral glans
Penile shaft Clitorial shaft
Testes ovaries
Prostate Skene’s gands
Cowper’s Glands Bartholin's glands
Scrotum Labia Majora




III. Basic Knowledge on Genetics and Obstetrics
1. DNA – carries genetic code
2. Chromosomes – threadlike strands composed of hereditary material – DNA
3. Normal amount of ejaculated sperm 3 – 5 cc., 1 tsp
4. Ovum is capable of being fertilized with in 24 – 36 hrs after ovulation
5. Sperm is viable within 48 – 72 hrs, 2-3 days
6. Reproductive cells divides by the process of meiosis (haploid)
Spermatogenesis – maturation of sperm
Oogenesis – process - maturation of ovum
Gematogenesis – formation of 2 haploid into diploid 23 + 23 = 46 or diploid
7. Age of Reproductivity – 15 – 44yo
8. Menstruation-
Menstrual Cycle – beginning of mens to beginning of next mens
Average Menstrual Cycle – 28 days
Average Menstrual Period - 3 – 5 days
Normal Blood loss – 50cc or ¼ cup
Related terminologies:
Menarche – 1st mens
Dysmenorrhea – painful mens
Metrorrhagia – bleeding between mens
Menorhagia – excessive during mens
Amenorrhea – absence of mens
Menopause – cessation of mens/ average : 51 years old
9. Functions of Estrogen and Progestin

* Estrogen “Hormone of the Woman” –
Primary function: development secondary sexual characteristic female.
Others:
1. inhibit production of FSH ( maturation of ovum)
2. hypertrophy of myometrium
3. Spinnbarkeit & Ferning ( billings method/ cervical)
4. development ductile structure of breast
5. increase osteoblast activities of long bones
6. increase in height in female
7. causes early closure of epiphysis of long bones
8. causes sodium retention
9. increase sexual desire

*Progestin “ Hormone of the Mother”
Primary function: prepares endometrium for implantation of fertilized ovum making it thick & tortous (twisted)
Secondary Function: uterine contractility (favors pregnancy)
Others: 1.inhibit prod of LH (hormone for ovulation)
2.inhibit motility of GIT
3. mammary gland development
4. increase permeability of kidney to lactose & dextrose causing (+) sugar
5. causes mood swings in moms
6. increase BBT

10. Menstrual Cycle
4 phases of Menstrual Cycle
1. Phases of Menstrual Cycle:
1. Proliferative
2. Secretory
3. Ischemic
4. Menses

Parts of body responsible for mens:
1. hypothalamus
2. anterior pituitary gland – master clock of body
3. ovaries
4. uterus
Initial phase – 3rd day – decreased estrogen
13th day – peak estrogen, decrease progesterone
14th day – Increase estrogen, increase progesterone
15th day – Decrease estrogen, increase progesterone
I. On the initial 3rd phase of menstruation , the estrogen level is decreased, this level stimulates the hypothalamus to release GnRH or FSHRF
II. GnRH/FSHRF – stimulates the anterior pituitary gland to release FSH
Functions of FSH:
1. Stimulate ovaries to release estrogen
2. Facilitate growth primary follicle to become graffian follicle (secrets large amt estrogen & contains mature ovum.)
III. Proliferative Phase – proliferation of tissue or follicular phase, post mens phase. Pre-ovularoty.
-phase of increase estrogen.

Follicular Phase – causing irregularities of mens
Postmenstrual Phase
Preovulatory Phase – phase increase estrogen

IV. 13th day of menstruation, estrogen level is peak while the progesterone level is down, these stimulates the hypothalamus to release GnRF on LHRF
1.) Mittelschmerz – slight abdominal pain on L or RQ of abdomen, marks ovulation day.
2.) Change in BBT, mood swing

V. GnRF/LHRF stimulates the ant pit gland to release LH.
Functions of LH:
1. (13th day-decreased progesterone) LH stimulates ovaries to release progesterone
2. hormone for ovulation
VI. 14th day estrogen level is increased while the progesterone level is increased causing rupture of graffian follicle on process of ovulation.

VII. 15th day, after ovulation day, graafian follicle starts to degenerate yellowish known as corpus luteum (secrets large amount of progesterone)

VIII. Secretory phase-
Lutheal Phase
Postovulatory PhaseIncreased progesterone
Premenstrual Phase

IX. 24th day if no fertilization, corpus luteum degenerate ( whitish – corpus albicans)

X. 28th day – if no sperm in ovum – endometrium begins to slough off to begin mens

Cornix- where sperm is deposited
Sperm- small head, long tail, pearly white
Phonones-vibration of head of sperm to determine location of ovum
Sperm should penetrate corona radiata and zona pellocida.
Capacitation- ability of sperm to release proteolytic enzyme to penetrate corona radiata and zona pellocida.

11. Stages of Sexual Responses (EPOR)
Initial responses:
Vasocongestion – congestion of blood vessels
Myotonia – increase muscle tension

1. Excitement Phase – (sign present in both sexes, moderate increase in HR, RR,BP, sex flush, nipple erection) – erotic stimuli cause increase sexual tension, lasts minutes to hours.

2. Plateau Phase – (accelerated V/S) – increasing & sustained tension nearing orgasm. Lasts 30 seconds – 3 minutes.
3. Orgasm – (involuntary spasm throughout body, peak v/s) involuntary release of sexual tension with physiologic or psychologic release, immeasurable peak of sexual experience. May last 2 – 10 sec- most affected are is pelvic area.

4. Resolution – (v/s return to normal, genitals return to pre-excitement phase)
Refractory Period – the only period present in males, wherein he cannot be restimulated for about 10-15 minutes

A. Fertilization
B. Stages of Fetal Growth and Development
3-4 days travel of zygote – mitotic cell division begins

*Pre-embryonic Stage
a. Zygote- fertilized ovum. Lifespan of zygote – from fertilization to 2 months
b. Morula – mulberry-like ball with 16 – 50 cells, 4 days free floating & multiplication
c. Blastocyst – enlarging cells that forms a cavity that later becomes the embryo. Blastocyst – covering of blastocys that later becomes placenta & trophoblast
d. Implantation/ Nidation- occurs after fertilization 7 – 10 days.
Fetus- 2 months to birth.
placenta previa – implantation at low side of uterus
Signs of implantation:
1. slight pain
2. slight vaginal spotting
- if with fertilization – corpus luteum continues to function & become source of estrogen & progesterone while placenta is not developed.

3 processes of Implantation
1. Apposition
2. Adhesion
3. Invasion

C. Dicidua – thickened endometrium ( Latin – falling off)
* Basalis (base) part of endometrium located under fetus where placenta is delivered
* Capsularies – encapsulate the fetus
* Vera – remaining portion of endometrium.

C. Chorionic Villi- 10 – 11th day, finger life projections
3 vessels=
A – unoxygenated blood
V – O2 blood

Long cord:cord coil or cord prolapse
b. Amniotic Fluid – bag of H2O, clear, odor mousy/musty, with crystallized forming pattern, slightly alkaline.
*Function of Amniotic Fluid:
1. cushions fetus against sudden blows or trauma
2. facilitates musculo-skeletal development
3. maintains temp
4. prevent cord compression
5. help in delivery process

normal amt of amniotic fluid – 500 to 1000cc

polyhydramnios, hydramnios- GIT malformation TEF/TEA, increased amt of fluid
oligohydramnios- decrease amt of fluid – kidney disease

Diagnostic Tests for Amniotic Fluid

A. Amniocentesis empty bladder before performing the procedure.
Purpose – obtain a sample of amniotic fluid by inserting a needle through the abdomen into the amniotic sac; fluid is tested for:
1. Genetic screening- maternal serum alpha feto-protein test (MSAFP) – 1st trimester
2. Determination of fetal maturity primarily by evaluating factors indicative of lung maturity – 3rd trimester
Testing time – 36 weeks
decreased MSAFP= down syndrome
increase MSAFP = spina bifida or open neural tube defect
Common complication of amniocenthesis – infection
Dangerous complications – spontaneous abortion
3rd trimester- pre term labor
Important factor to consider for amniocentesis- needle insertion site
Aspiration of yellowish amniotic fluid – jaundice baby
Greenish – meconium

A. Amnioscopy – direct visualization or exam to an intact fetal membrane.
B. Fern Test- determine if amniotic fluid has ruptured or not (blue paper turns green/grey - + ruptured amniotic fluid)
C. Nitrazine Paper Test – diff amniotic fluid & urine.
Paper turns yellow- urine. Paper turns blue green/gray-(+) rupture of amn fluid.

7. Leopold’s Maneuver
Purpose: is done to determine the attitude, fetal presentation lie, presenting part, degree of descent, an estimate of the size, and number of fetuses, position, fetal back & fetal heart tone
- use palm! Warm palm.

Prep mom:
1. Empty bladder
2. Position of mom-supine with knee flex (dorsal recumbent – to relax abdominal muscles)
Procedure:
1st maneuver: place patient in supine position with knees slightly flexed; put towel under head and right hip; with both hands palpate upper abdomen and fundus. Assess size, shape, movement and firmness of the part to determine presentation

2nd Maneuver: with both hands moving down, identify the back of the fetus ( to hear fetal heart sound) where the ball of the stethoscope is placed to determine FHT. Get V/S(before 2nd maneuver) PR to diff fundic soufflé (FHR) & uterine soufflé.
Uterine soufflé – maternal H rate

3rd Maneuver: using the right hand, grasp the symphis pubis part using thumb and fingers.
To determine degree of engagement.

Assess whether the presenting part is engaged in the pelvis )Alert : if the head is engaged it will not be movable).

4th Maneuver: the Examiner changes the position by facing the patient’s feet. With two hands, assess the descent of the presenting part by locating the cephalic prominence or brow. To determine attitude – relationship of fetus to 1 another.

When the brow is on the same side as the back, the head is extended. When the brow is on the same side as the small parts, the head will be flexed and vertex presenting.

Attitude – relationship of fetus to a part – or degree of flexion
Full flexion – when the chin touches the chest








8.Assessment of Fetal Well-Being-
A. Daily Fetal Movement Counting (DFMC) –begin 27 weeks
Mom- begin after meal - breakfast

a. Cardiff count to 10 method – one method currently available
(1) Begin at the same time each day (usually in the morning, after breakfast) and count each fetal movement, noting how long it takes to count 10 fetal movements (FMs)
(2) Expected findings – 10 movements in 1 hour or less
3) Warning signs
a.) more then 1 hour to reach 10 movements
b.) less then 10 movements in 12 hours(non-reactive- fetal distress)
c.) longer time to reach 10 FMs than on previous days
d.) movement are becoming weaker, less vigorous
Movement alarm signals - < 3 FMs in 12 hours
4.) warning signs should be reported to healthcare provider immediately; often require further testing. Examples: nonstress test (NST), biographical profile (BPP)

B. Nonstress test – to determine the response of the fetal heart rate to activity
Indication – pregnancies at risk for placental insufficiency
Postmaturity
a.) pregnancy induced hypertension (PIH), diabetes
b.) warning signs noted during DFMC
c.) maternal history of smoking, inadequate nutrition

Procedure:
Done within 30 minutes wherein the mother is in semi-fowler’s position (w/ fetal monitor); external monitor is applied to document fetal activity; mother activates the “mark button” on the electronic monitor when she feels fetal movement.

Attach external noninvasive fetal monitors
1. tocotransducer over fundus to detect uterine contractions and fetal movements (FMs)
2. ultrasound transducer over abdominal site where most distinct fetal heart sounds are detected
3. monitor until at least 2 FMs are detected in 20 minutes
if no FM after 40 minutes provide woman with a light snack or gently stimulate fetus through abdomen
if no FM after 1 hour further testing may be indicated, such as a CST

Result:
Noncreative
Nonstress
Not Good
Reactive
Responsive is
Real Good

Interpretation of results
i. reactive result
1. Baseline FHR between 120 and 160 beats per minute
2. At least two accelerations of the FHR of at least 15 beats per minute, lasting at least 15 seconds in a 10 to 20 minute period as a result of FM
3. Good variability – normal irregularity of cardiac rhythm representing a balanced interaction between the parasympathetic (decreases FHR) and sympathetic (increase FHR) nervous system; noted as an uneven line on the rhythm strip.
4. result indicates a healthy fetus with an intact nervous system

ii. Nonreactive result
1. Stated criteria for a reactive result are not met
2. Could be indicative of a compromised fetus.
Requires further evaluation with another NST, biophysical profile, (BPP) or contraction stress test (CST)

9. Health teachings
a. Nutrition – do nutritional assessment – daily food intake
High risk moms:
1. Pregnant teenagers – low compliance to heath regimen.
2. Extremes in wt – underweight, over wt – candidate for HPN, DM
3. Low socio – economic status
4. Vegetarian mom – decrease CHON – needs Vit B12 – cyanocobalamin – formation of folic acid – needed for cell DNA & RBC formation. (Decrease folic acid – spina bifida/open neural tube defect)

Recommended Nutrient Requirement that increases During Pregnancy
Nutrients
Requirements
Food Source
Calories
Essential to supply energy for
increased metabolic rate
utilization of nutrients
protein sparing so it can be used for
Growth of fetus
Development of structures required for pregnancy including placenta, amniotic fluid, and tissue growth.
300 calories/day above the prepregnancy daily requirement to maintain ideal body weight and meet energy requirement to activity level
Begin increase in second trimester
Use weight – gain pattern as an indication of adequacy of calorie intake.
Failure to meet caloric requirements can lead to ketosis as fat and protein are used for energy; ketosis has been associated with fetal damage.


Caloric increase should reflect
Foods of high nutrient value such as protein, complex carbohydrates (whole grains, vegetables, fruits)
Variety of foods representing foods sources for the nutrients requiring during pregnancy
No more than 30% fat

Protein
Essential for:
Fetal tissue growth
Maternal tissue growth including uterus and breasts
Development of essential pregnancy structures
Formation of red blood cells and plasma proteins
* Inadequate protein intake has been associated with onset of pregnancy induces hypertension (PIH)
60 mg/day or an increase of 10% above daily requirements for age group

Adolescents have a higher protein requirement than mature women since adolescents must supply protein for their own growth as well as protein t meet the pregnancy requirement


Protein increase should reflect
Lean meat, poultry, fish
Eggs, cheese, milk
Dried beans, lentils, nuts
Whole grains
* vegetarians must take note of the amino acid content of CHON foods consumed to ensure ingestion of sufficient quantities of all amino acids
Calcium-Phosphorous
Essential for
Growth and development of fetal skeleton and tooth buds
Maintenance of mineralization of maternal bones and teeth
Current research is :
Demonstrating an association between adequate calcium intake and the prevention of pregnancy induce hypertension

Calcium increases of
1200 mg/day representing an increase of 50% above prepregnancy daily requirement.
1600 mg/day is recommended for the adolescent. 10 mcg/day of vitamin D is required since it enhances absorption of both calcium and phosphorous
Calcium increases should reflect:
dairy products : milk, yogurt, ice cream, cheese, egg yolk
whole grains, tofu
green leafy vegetables
canned salmon & sardines w/ bones
Ca fortified foods such as orange juice
Vitamin D sources: fortified milk, margarine, egg yolk, butter, liver, seafood
Iron
Essential for
Expansion of blood volume and red blood cells formation
Establishment of fetal iron stores for first few months of life
30 mg/day representing a doubling of the pregnant daily requirement
Begin supplementation at 30- mg/day in second trimester, since diet alone is unable to meet pregnancy requirement
60 – 120 mg/day along with copper and zinc supplementation for women who have low hemoglobin values prior to pregnancy or who have iron deficiency anemia.
70 mg/day of vitamin C which enhances iron absorption
inadequate iron intake results in maternal effects – anemia depletion of iron stores, decreased energy and appetite, cardiac stress especially labor and birth
fetal effects decreased availability of oxygen thereby affecting fetal growth
* iron deficiency anemia is the most common nutritional disorder of pregnancy.
Iron increases should reflect
liver, red meat, fish, poultry, eggs
enriched, whole grain cereals and breads
dark green leafy vegetables, legumes
nuts, dried fruits
vitamin C sources: citrus fruits & juices, strawberries, cantaloupe, broccoli or cabbage, potatoes
iron from food sources is more readily absorbed when served with foods high in vit C

Zinc
Essential for
* the formation of enzymes
* maybe important in the prevention of congenital malformation of the fetus.
15mcg/day representing an increase of 3 mg/day over prepreganant daily requirements.
Zinc increases should reflect
liver, meats
shell fish
eggs, milk, cheese
whole grains, legumes, nuts
Folic Acid, Folacin, Folate
Essential for
formation of red blood cells and prevention of anemia
DNA synthesis and cell formation; may play a role in the prevention of neutral tube defects (spina bifida), abortion, abruption placenta
400 mcg/day representing an increase of more then 2 times the daily prepregnant requirement. 300mcg/day supplement for women with low folate levels or dietary deficiency
4 servings of grains/day
Increases should reflect
liver, kidney, lean beef, veal
dark green leafy vegetables, broccoli, legumes.
Whole grains, peanuts
Additional Requirements
Minerals
iodine
Magnesium
Selenium


175 mcg/day
320 mg/day
65 mcg/day
Increased requirements of pregnancy can easily be met with a balanced diet that meets the requirement for calories and includes food sources high in the other nutrients needed during pregnancy.
Vitamins
E
Thiamine
Riborlavin
Pyridoxine ( B6)
B12
Niacin

10 mg/day
1.5 mg/day
1.6 mg/day
2.2 mg/day
2.2 mg day
17 mg/day
Vit stored in body. Taking it not needed – fat soluble vitamins. Hard to excrete.

2.Sexual Activity
a.) should be done in moderation
b.) should be done in private place
c.) mom placed in comfy pos, sidelying or mom on top
d.) avoided 6 weeks prior to EDD
e.) avoid blowing or air during cunnilingus
f.) changes in sexual desire of mom during preg- air embolism
Changes in sexual desire:
a.) 1st tri – decrease desire – due to bodily changes
b.) 2nd trimester – increased desire due to increase estrogen that enhances lubrication
c.) 3rd trimester – decreased desire

Contraindication in sex:
1. vaginal spotting
1st trimester – threatened abortion
2nd trimester– placenta previa
2. incompetent cervix
3. preterm labor
4. premature rupture of membrane

3. Exercise – to strengthen muscles used during delivery process
principles of exercise
1.) Done in moderation. 2.) Must be individualized
Walking – best exercise

Squatting – strengthen muscles of perineum. Increase circulation to perineum. Squat – feet flat on floor

Tailor Sitting – 1 leg in front of other leg ( Indian seat)

Raise buttocks 1st before head to prevent postural hypotension – dizziness when changing position


shoulder circling exercise- strengthen chest muscles
pelvic rocking/pelvic tilt- exercise – relieves low back pain & maintain good posture
* arch back – standing or kneeling. Four extremities on floor

Kegel Exercise – strengthen pulococcygeal muscles
- as if hold urine, release 10x or muscle contraction

Abdominal Exercise – strengthens muscles of abdominal – done as if blowing candle

4. Childbirth Preparation:
Overall goal: to prepare parents physically and psychologically while promoting wellness behavior that can be used by parents and family thus, helping them achieved a satisfying and enjoying childbirth experience.

a. Psychophysical
1. Bradley Method – Dr. Robert Bradley – advocated active participation of husband at delivery process. Based on imitation of nature.

Features:
1.) darkened rm
2.) quiet environment
3.) relaxation tech
4.) closed eye & appearance of sleep

2. Grantly Dick Read Method – fear leads to tension while tension leads to pain

b. Psychosexual
1. Kitzinger method – preg, labor & birth & care of newborn is an impt turning pt in woman’s life cycle
- flow with contraction than struggle with contraction

c. Psychoprophylaxis – prevention of pain
1. Lamaze: Dr. Ferdinand Lamaze
req. disciple, conditioning & concentration. Husband is coach
Features:
1. Conscious relaxation
2. Cleansing breathe – inhale nose, exhale mouth
3. Effleurage – gentle circular massage over abdominal to relieve pain
4. imaging – sensate focus


5. Different Methods of delivery:
1.) birthing chair – bed convertible to chair – semifowlers
2.) birthing bed – dorsal recumbent pos
3.) squatting – relives low back pain during labor pain
4.) leboyers – warm, quiet, dark, comfy room. After delivery, baby gets warm bath.
5.) Birth under H20 – bathtub – labor & delivery – warm water, soft music.

IX. Intrapartal Notes – inside ER
A. Admitting the laboring Mother:
Personal Data: name, age, address, etc
Baseline Data: v/s esppecially BP, weight
Obstetrical Data: gravida # preg, para- viable preg, – 22 – 24 wks
Physical Exams,Pelvic Exams

B. Basic knowledge in Intrapartum.

b. 1 Theories of the Onset of Labor
1.) uterine stretch theory ( any hallow organ stretched, will always contract & expel its content) – contraction action
2.) oxytocin theory – post pit gland releases oxytocin. Hypothalamus produces oxytocin
3.) prostaglandin theory – stimulation of arachidonic acid – prostaglandin- contraction
4.) progesterone theory – before labor, decrease progesterone will stimulate contractions & labor
5.) theory of aging placenta – life span of placenta 42 wks. At 36 wks degenerates (leading to contraction – onset labor).

b.2. The 4 P’s of labor

1. Passenger
a. Fetal head – is the largest presenting part – common presenting part – ¼ of its length.
Bones – 6 bones S – sphenoid F – frontal - sinciput
E – ethmoid O – occuputal - occiput
T – temporal P – parietal 2 x
Measurement fetal head:
1. transverse diameter – 9.25cm
biparietal – largest transverse
bitemporal 8 cm
2. bimastoid 7cm smallest transverse

Sutures – intermembranous spaces that allow molding.
1.) sagittal suture – connects 2 parietal bones ( sagitna)
2.) coronal suture – connect parietal & frontal bone (crown)
3.) lambdoidal suture – connects occipital & parietal bone

Moldings: the overlapping of the sutures of the skull to permit passage of the head to the pelvis

Fontanels:
1.) Anterior fontanel – bregma, diamond shape, 3 x 4 cm,( > 5 cm – hydrocephalus), 12 – 18 months after birth- close
2.) Posterior fontanel or lambda – triangular shape, 1 x 1 cm. Closes – 2 – 3 months.
4.) Anteroposterior diameter -
suboccipitobregmatic 9.5 cm, complete flexion, smallest AP
occipitofrontal 12cm partial flexion
occipitomental – 13.5 cm hyper extension submentobragmatic-face presentation

2. Passageway
Mom 1.) < 4’9” tall
2.) < 18 years old
3.) Underwent pelvic dislocation
Pelvis
4 main pelvic types
1. Gynecoid – round, wide, deeper most suitable (normal female pelvis) for pregnancy
2. Android – heart shape “male pelvis”- anterior part pointed, posterior part shallow
3. Anthropoid – oval, ape like pelvis, oval shape, AP diameter wider transverse narrow
4. Platypelloid – flat AP diameter – narrow, transverse – wider

b. Pelvis
2 hip bones – 2 innominate bones
3 Parts of 2 Innominate Bones
Ileum – lateral side of hips
- iliac crest – flaring superior border forming prominence of hips
Ischium – inferior portion
- ischial tuberosity where we sit – landmark to get external measurement of pelvis
Pubes – ant portion – symphisis pubis junction between 2 pubis
1 sacrum – post portion – sacral prominence – landmark to get internal measurement of pelvis
1 coccyx – 5 small bones compresses during vaginal delivery


Important Measurements

1. Diagonal Conjugate – measure between sacral promontory and inferior margin of the symphysis pubis.
Measurement: 11.5 cm - 12.5 cm basis in getting true conjugate. (DC – 11.5 cm=true conjugate)

2. True conjugate/conjugate vera – measure between the anterior surface of the sacral promontory and superior margin of the symphysis pubis. Measurement: 11.0 cm

3. Obstetrical conjugate – smallest AP diameter. Pelvis at 10 cm or more.

Tuberoischi Diameter – transverse diameter of the pelvic outlet. Ischial tuberosity – approximated with use of fist – 8 cm & above.

3. Power – the force acting to expel the fetus and placenta – myometrium – powers of labor
a. Involuntary Contractions
b. Voluntary bearing down efforts
c. Characteristics: wave like
d. Timing: frequency, duration, intensity
4. Psyche/Person – psychological stress when the mother is fighting the labor experience
a. Cultural Interpretation
b. Preparation
c. Past Experience
d. Support System

Pre-eminent Signs of Labor
S&Sx:
- shooting pain radiating to the legs
- urinary freq.
1. Lightening – setting of presenting part into pelvic brim - 2 weeks prior to EDD
* Engagement- setting of presenting part into pelvic inlet
2. Braxton Hicks Contractions – painless irregular contractions
3. Increase Activity of the Mother- nesting instinct. Save energy, will be used for delivery. Increase epinephrine
4. Ripening of the Cervix – butter soft
5. decreased body wt – 1.5 – 3 lbs
6. Bloody Show – pinkish vaginal discharge – blood & leukorrhea
7. Rupture of Membranes – rupture of water. Check FHT

Premature Rupture of Membrane ( PROM) - do IE to check for cord prolapse
Contraction drop in intensity even though very painful
Contraction drop in frequently
Uterus tense and/or contracting between contractions
Abdominal palpations

Nursing Care;
Administer Analgesics (Morphine)
Attempt manual rotation for ROP or LOP – most common malposition
Bear down with contractions
Adequate hydration – prepare for CS
Sedation as ordered
Cesarean delivery may be required, especially if fetal distress is noted

Cord Prolapse – a complication when the umbilical cord falls or is washed through the cervix into the vagina.

Danger signs:
PROM
Presenting part has not yet engaged
Fetal distress
Protruding cord form vagina



Nursing care:
1. Cover cord with sterile gauze with saline to prevent drying of cord so cord will remain slippery & prevent cord compression causing cerebral palsy.
2. Slip cord away from presenting part
3. Count pulsation of cord for FHT
4. Prep mom for CS

Positioning – trendelenberg or knee chest position
Emotional support
Prepare for Cesarean Section

Difference Between True Labor and False Labor
False Labor
True Labor
Irregular contractions
No increase in intensity
Pain – confined to abdomen
Pain – relived by walking
No cervical changes
Contractions are regular
Increased intensity
Pain – begins lower back radiates to abdomen
Pain – intensified by walking
Cervical effacement & dilatation * major sx
of true labor.
Duration of Labor
Primipara – 14 hrs & not more than 20 hrs
Multipara – 8 hrs & not > 14 hrs

Effacement – softening & thinning of cervix. Use % in unit of measurement
Dilation – widening of cervix. Unit used is cm.

Nursing Interventions in Each Stage of Labor

2 segments of the uterus
1. upper uterine - fundus
2. lower uterine – isthmus

1. First Stage: onset of true contractions to full dilation and effacement of cervix.
Latent Phase:
Assessment: Dilations: 0 – 3 cm mom – excited, apprehensive, can communicate
Frequency: every 5 – 10 min
Intensity mild
Nursing Care:
1. Encourage walking - shorten 1st stage of labor
2. Encourage to void q 2 – 3 hrs – full bladder inhibit contractions
3. Breathing – chest breathing

Active Phase:
Assessment: Dilations 4 -8 cm Intensity: moderate Mom- fears losing control of self
Frequency q 3-5 min lasting for 30 – 60 seconds

Nursing Care:
M – edications – have meds ready
A – ssessment include: vital signs, cervical dilation and effacement, fetal monitor, etc.
D – dry lips – oral care (ointment)
dry linens
B – abdominal breathing

Transitional Phase: intensity: strong Mom – mood changes with hyperesthesia
Assessment: Dilations 8 – 10 cm
Frequency q 2-3 min contractions
Durations 45 – 90 seconds

Hyperesthesia – increase sensitivity to touch, pain all over
Health Teaching : teach: sacral pressure on lower back to inhibit transmission of pain
keep informed of progress
controlled chest breathing
Nursing Care:
T – ires
I – nform of progress
R – estless support her breathing technique
E – ncourage and praise
D – iscomfort

Pelvic Exams
Effacement
Dilation
a. Station – landmark used: ischial spine
- 1 station = presenting part 1cm above ischial spine if (-) floating
- 2 station = presenting part 2 cm above ischial spine if (-) floating
0 station = level at ischial spine – engagement
+ 1 station = below 1 cm ischial spine
+3 to +5 = crowning – occurs at 2nd stage of labor

b. Presentation/lie – the relationship of the long axis (spine) of the fetus to the long axis of the mother
-spine of mom and spine of fetus
Two types:
b.1. Longitudinal Lie ( Parallel)
cephalic - Vertex – complete flexion
Face
Brow Poor Flexion
Chin
Breech - Complete Breech – thigh breast on abdomen, breast lie on thigh
Incomplete Breech – thigh rest on abdominal
Frank – legs extend to head
Footling – single, double
Kneeling

b.2. Transverse Lie (Perpendicular) or Perpendicular lie. Shoulder presentation.

c. Position – relationship of the fatal presenting part to specific quadrant of the mother’s pelvis.

Variety:
Occipito – LOA left occipito ant (most common and favorable position)– side of maternal pelvis
LOP – left occipito posterior
LOP – most common mal position, most painful
ROP – squatting pos on mom
ROT
ROA

Breech- use sacrum LSA – left sacro anterior
- put stet above umbilicus LST, LSP, RSA, RST, RSP
Shoulder/acromniodorso
LADA, LADT, LADP, RADA

Chin / Mento
LMA, LMT, LMP, RMP, RMA, RMT, RMP

Monitoring the Contractions and Fetal heart Tone
Spread fingers lightly over fundus – to monitor contractions

Parts of contractions:
Increment or crescendo – beginning of contractions until it increases
Acme or apex – height of contraction
Decrement or decrescendo – from height of contractions until it decreases
Duration – beginning of contractions to end of same contraction
Interval – end of 1 contraction to beginning of next contraction
Frequency – beginning of 1 contraction to beginning of next contraction
Intensity - strength of contraction

Contraction – vasoconstriction
Increase BP, decrease FHT
Best time to get BP & FHT just after a contraction or midway of contractions

Placental reserve – 60 sec o2 for fetus during contractions
Duration of contractions shouldn’t >60 sec
Notify MD

Mom has headache – check BP, if same BP, let mom rest. If BP increase , notify MD -preeclampsia
Health teachings
1.) Ok to shower
2.)NPO – GIT stops function during labor if with food- will cause aspiration
3.)Enema administer during labor
a.)To cleanse bowel
b.)Prevent infection
c.)Sims position/side lying
12 – 18 inch – ht enema tubing

Check FHT after adm enema
Normal FHT= 120-160

Signs of fetal distress-
1.) <120 & >160
2.) mecomium stain amnion fluid
3.) fetal thrushing – hyperactive fetus due to lack O2

2. Second Stage: fetal stage, complete dilation and effacement to birth.

7 – 8 multi – bring to delivery room
10cm primi – bring to delivery room
Lithotomy pos – put legs same time up
Bulging of perineum – sure to come out
Breathing – panting ( teach mom)
Assist doc in doing episiotomy- to prevent laceration, widen vaginal canal, shorten 2nd stage of labor.
Episiotomy – median – less bleeding, less pain easy to repair, fast to heal, possible to reach rectum ( urethroanal fistula)
Mediolateral – more bleeding & pain, hard to repair, slow to heal
-use local or pudendal anesthesia.

Ironing the perineum – to prevent laceration
Modified Ritgens maneuver – place towel at perineum
1.)To prevent laceration
2.) Will facilitate complete flexion & extension. (Support head & remove secretion, check cord if coiled. Pull shoulder down & up. Check time, identification of baby.

Mechanisms of labor
1. Engagement -
2. Descent
3. Flexion
4. Internal Rotation
5. Extension
6. External rotation
7. Expulsion

Three parts of Pelvis – 1. Inlet – AP diameter narrow, transverse diameter wider
2. Cavity
Two Major Divisions of Pelvis
1. True pelvis – below the pelvic inlet
2. False pelvis – above the pelvic inlet; supports uterus during pregnancy


Linea Terminales diagonal imaginary line from the sacrum to the symphysis pubis that divides the false and true pelvis.
Nursing Care:
To prevent puerperal sepsis - < 48 hours only – vaginal pack

Bolus of Ptocin can lead to hypotension.


3. Third Stage: birth to expulsion of Placenta -placental stage placenta has 15 – 28 cotyledons
Placenta delivered from 3-10 minutes
Signs of placental separation
1. Fundus rises – becomes firm & globular “ Calkins sign”
2. Lengthening of the cord
3. Sudden gush of blood

Types of placental delivery
Shultz “shiny” – begins to separate from center to edges presenting the fetal side shiny
Dunkan “dirty” – begin to separate form edges to center presenting natural side – beefy red or dirty

Slowly pull cord and wind to clamp – BRANDT ANDREWS MANEUVER
Hurrying of placental delivery will lead to inversion of uterus.

Nsg care for placenta:
4. Check completeness of placenta.
5. Check fundus (if relaxed, massage uterus)
6. Check bp
7. Administer methergine IM (Methylergonovine Maleate) “Ergotrate derivatives
8. Monitor hpn (or give oxytocin IV)
9. Check perineum for lacerations
10. Assist MD for episiorapy
11. Flat on bed
12. Chills-due dehydration. Blanket, give clear liquid-tea, ginger ale, clear gelatin. Let mom sleep to regain energy.

4. Fourth Stage: the first 1-2 hours after delivery of placenta – recovery stage. Monitor v/s q 15 for 1 hr. 2nd hr q 30 minutes.
Check placement of fundus at level of umbilicus.

If fundus above umbilicus, deviation of fundus
1.) Empty bladder to prevent uterine atony
2.) Check lochia
a. Maternal Observations – body system stabilizes
b. Placement of the Fundus
c. Lochia

d. Perineum –
R - edness
E- dema
E - cchemosis
D – ischarges
A – approximation of blood loss. Count pad & saturation

Fully soaked pad : 30 – 40 cc weigh pad. 1 gram=1cc

e. Bonding – interaction between mother and newborn – rooming in types
1.) Straight rooming in baby: 24hrs with mom.
2.) Partial rooming in: baby in morning , at night nursery




Complications of Labor
Dystocia – difficult labor related to:
Mechanical factor – due to uterine inertia – sluggishness of contraction
1.) hypertonic or primary uterine inertia
intense excessive contractions resulting to ineffective pushing
MD administer sedative valium,/diazepam – muscle relaxant
2.) hypotonic – secondary uterine inertia- slow irregular contraction resulting to ineffective pushing. Give oxytocin.

Prolonged labor – normal length of labor in primi 14 – 20 hrs
Multi 10 -14 hrs
> 14 hrs in multi & > 20 hrs in primi
maternal effect – exhaustion. Fetal effect – fetal distress, caput succedaneum or cephal hematoma
nsg care: monitor contractions and FHR

Precipitate Labor - labor of < 3 hrs. extensive lacerations, profuse bleeding, hypovolemic shock if with bleeding.
Earliest sign: tachycardia & restlessness
Late sign: hypotension
Outstanding Nursing dx: fluid volume deficit
Post of mom – modified trendelenberg
IV – fast drip due fluid volume def

Signs of Hypovolemic Shock:
Hypotension
Tachycardia
Tachypnea
Cold clammy skin

Inversion of the uterus – situation uterus is inside out.
MD will push uterus back inside or not hysterectomy.

Factors leading to inversion of uterus
1.) short cord
2.) hurrying of placental delivery
3.) ineffective fundal pressure

Uterine Rupture
Causes: 1.)
1.)Previous classical CS
2.)Large baby
3.) Improper use of oxytocin (IV drip)
Sx:
a.) sudden pain
b.) profuse bleeding
c.) hypovolemic shock
d.) TAHBSO
Physiologic retraction ring
Boundary bet upper/lower uterine segment
BANDL’S pathologic ring – suprapubic depression
a.) sign of impending uterine rupture

Amniotic Fluid Embolism or placental embolism – amniotic fluid or fragments of placenta enters natural circulation resulting to embolism
Sx:
dyspnea, chest pain & frothy sputum
prepare: suctioning
end stage: DIC disseminated intravascular coagopathy- bleeding to all portions of the body – eyes, nose, etc.

Trial Labor – measurement of head & pelvis falls on borderline. Mom given 6 hrs of labor
Multi: 8 – 14, primi 14 – 20

Preterm Labor – labor after 20 – 37 weeks) ( abortion <20 weeks)
Sx:
1. premature contractions q 10 min
2. effacement of 60 – 80%
3. dilation 2-3 cm

Home Mgt:
1. complete bed rest
2. avoid sex
3. empty bladder
4. drink 3 -4 glasses of water – full bladder inhibits contractions
5. consult MD if symptoms persist

Hosp:
1. If cervix is closed 2 – 3 cm, dilation saved by administer Tocolytic agents- halts preterm contractions.YUTOPAR- Yutopar Hcl)
150mg incorporated 500cc Dextrose piggyback.
Monitor: FHT > 180 bpm
Maternal BP - <90/60
Crackles – notify MD – pulmo edema – administer oral yutopar 30 minutes before d/c IV
Tocolytic (Phil)
Terbuthaline (Bricanyl or Brethine) – sustained tachycardia
Antidote – propranolol or inderal - beta-blocker

If cervix is open – MD – steroid dextamethzone (betamethazone) to facilitate surfactant maturation preventing RDS

Preterm-cut cord ASAP to prevent jaundice or hyperbilirubenia.


X. Postpartal Period 5th stage of labor
after 24hrs :Normal increase WBC up to 30,000 cumm

Puerperium – covers 1st 6 wks post partum
Involution – return of repro organ to its non pregnant state.
Hyperfibrinogenia
- prone to thrombus formation
- early ambulation

Principles underlying puerperium
1. To return to Normal and Facilitate healing

A. Physiologic Changes
a.1. Systemic Changes

1. Cardiovascular System
- the first few minutes after delivery is the most critical period in mothers because the increased in plasma volume return to its normal state and thus adding to the workload of the heart. This is critical especially to gravidocardiac mothers.

2. Genital tract
a. Cervix – cervical opening
b. Vaginal and Pelvic Floor
c. Uterus – return to normal 6 – 8 wks. Fundus goes down 1 finger breath/day until 10th day – no longer palpable due behind symphisis pubis
3 days after post partum: sub involuted uterus – delayed healing uterus with big clots of blood- a medium for bacterial growth- (puerperal sepsis)- D&C
after, birth pain:
1. position prone
2. cold compress – to prevent bleeding
3. mefenamic acid

d. Lochia-bld, wbc, deciduas, microorganism. Nsd & Cs with lochia.
1. Ruba – red 1st 3 days present, musty/mousy, moderate amt
2. Serosa – pink to brown 4 – 9th day, limited amt
3. Alba – créme white 10 – 21 days very decreased amt
dysuria
- urine collection
- alternate warm & cold compress
- stimulate bladder

3. Urinary tract: Bladder – freq in urination after delivery- urinary retention with overflow
4. Colon: Constipation – due NPO, fear of bearing down
5. Perineal area – painful – episiotomy site – sims pos, cold compress for immediate pain after 24 hrs, hot sitz bath, not compress
sex- when perineum has healed

II. Provide Emotional Support – Reva Rubia
Psychological Responses:
a. Taking in phase – dependent phase (1st three days) mom – passive, cant make decisions, activity is to tell child birth experiences.
Nursing Care: - proper hygiene
b. Taking hold phase – dependent to independent phase (4 to 7 days). Mom is active, can make decisions
HT:
1.) Care of newborn
2.) Insert family planting method
common post partum blues/ baby blues present 4 – 5 days 50-80% moms – overwhelming feeling of depression characterized by crying, despondence- inability to sleep & lack of appetite. – let mom cry – therapeutic.

c. Letting go – interdependent phase – 7 days & above. Mom - redefines new roles may extend until child grows.

III. Prevent complications

1. Hemorrhage – bleeding of > 500cc
CS – 600 – 800 cc normal
NSD 500 cc

I. Early postpartum hemorrhage– bleeding within 1st 24 hrs. Baggy or relaxed uterus & profuse bleeding – uterine atony. Complications: hypovolemic shock.
Mgt:
1.) massage uterus until contracted
2.) cold compress
3.) modified trendelenberg
4.) IV fast drip/ oxytocin IV drip

1st degree laceration – affects vaginal skin & mucus membrane.
2nd degree – 1st degree + muscles of vagina
3rd degree – 2nd degree + external sphincter of rectum
4th degree – 3rd degree + mucus membrane of rectum




Breast feeding – post pit gland will release oxytocin so uterus will contract.
Well contracted uterus + bleeding = laceration
assess perineum for laceration
degree of laceration
mgt episiorapy

DIC – Disseminated Intravascular Coagulopathy. Hypofibrinogen- failure to coagulate.
bleeding to any part of body
hysterectomy if with abruption placenta
mgt: BT- cryoprecipitate or fresh frozen plasma

II. Late Postpartum hemorrhage – bleeding after 24 hrs – retained placental fragments
Mgt: D&C or manual extraction of fragments & massaging of uterus. D&C except placenta increta, percreta,

Acreta – attached placenta to myometrium.
Increta – deeper attachment of placenta to myometrium hysterectomy
Percreta – invasion of placenta to perimetrium

Hematoma – bluish or purple discoloration of SQ tissue of vagina or perineum.
too much manipulation
large baby
pudendal anesthesia
Mgt:
1.) cold compress every 30 minutes with rest period of 30 minutes for 24 hrs
2.) shave
3.) incision on site, scraping & suturing

Infection- sources of infection
1.)endogenous – from within body
2.) exogenous – from outside
1.) anaerobic streptococci – most common - from members health team
2.) unhealthy sexual practices
General signs of inflammation:
1. Inflammation – calor (heat), rubor (red), dolor (pain) tumor(swelling)
2. purulent discharges
3. fever

Gen mgt:
1.) supportive care – CBR, hydration, TSB, cold compress, paracetamol, VITC, culture & sensitivity – for antibiotic

prolonged use of antibiotic lead to fungal infection
inflammation of perineum – see general signs of inflammation
2 to 3 stitches dislocated with purulent discharge
Mgt:
Removal of sutures & drainage, saline, between & resulting.
Endometriosis – inflammation of endometrial lining
Sx:
Abdominal tenderness, pos.
Fowlers – to facilitate drainage & localize infection oxytocin & antibiotic

IV. Motivate the use of Family Planning
1.) determine one’s own beliefs 1st
2.) never advice a permanent method of planning
3.) method of choice is an individuals choice.

Natural Method – the only method accepted by the Catholic Church
Billings / Cervical mucus– test spinnbarkeit & ferning (estrogen)
clear, watery, stretchable, elastic – long spinnbarkeit
Basal Body Temperature 13th day temp goes down before ovulation – no sex
get before arising in bed

LAM – lactation amenorrheal method – hormone that inhibits ovulation is prolactin.
breast feeding- menstruation will come out 4 – 6 months
bottle fed 2 – 3 months
disadvantage of lam – might get pregnant

Symptothermal – combination of BBT & cervical. Best method

Social Method – 1.) coitus interuptus/ withdrawal - least effective method
2. coitus reservatus – sex without ejaculation –
3. coitus interfemora – “ipit”
4. calendar method

OVULATION –count minus 14 days before next mens (14 days before next mens)

Origoknause formula –
monitor cycle for 1 year
-get short test & longest cycle from Jan – Dec
shortest – 18
longest – 11

June 26 Dec 33
- 18 -11
8 - 22 unsafe days

21 day pill- start 5th day of mens
28day pill- start 1st day of mens
missed 1 pill – take 2 next day

Physiologic Method-

Pills – combined oral contraceptives prevent ovulation by inhibiting the anterior pituitary gland production of FSH and LH which are essential for the maturation and rupture of a follicle. 99.9% effective. Waiting time to become pregnant- 3 months. Consult OB-6mos.

Alerts on Oral Contraceptive:

-in case a mother who is taking an oral contraceptive for almost long time plans to have a baby, she would wait for at least 3 months before attempting to conceive to provide time for the estrogen and progesterone levels to return to normal.
- if a new oral contraceptive is prescribed the mother should continue taking the previously prescribed contraceptive and begin taking the new one on the first day of the next menses.
- discontinue oral contraceptive if there is signs of severe headache as this is an indication of hypertension associated with increase incidence of CVA and subarachnoid hemorrhage.

Signs of hypertension
Immediate Discontinuation
A – abdominal pain
C – chest pain
H - headache
E – eye problems
S – severe leg cramps
If mom HPN – stop pills STAT!
Adverse effect: breakthrough bleeding
Contraindicated:
1.) chain smoker
2.) extreme obesity
3.) HPN
4.) DM
5.) Thrombophlebitis or problems in clotting factors

if forgotten for one day, immediately take the forgotten tablet plus the tablet scheduled that day. If forgotten for two consecutive days, or more days, use another method for the rest of the cycle and the start again.

DMPA – depoproveda – has progesterone inhibits LH – inhibits ovulation
Depomedroxy progesterone acetate – IM q 3 months
- never massage injected site, it will shorten duration

Norplant – has 6 match sticks – like capsules implanted subdermally containing progesterone.
5 yrs – disadvantage if keloid skin
as soon as removed – can become pregnant

Mechanism and Chemical Barriers


Intrauterine Device (IUD)
Action: prevents implantation – affects motility of sperm & ovum
right time to insert is after delivery or during menstruation

primary indication for use of IUD
parity or # of children, if 1 kid only don’t use IUD

HT:
1.) Check for string daily
2.) Monthly checkup
3.) Regular pap smear
Alerts;
prevents implantation
most common complications: excessive menstrual flow and expulsion of the device (common problem)
others:
P eriod late (pregnancy suspected)
Abnormal spotting or bleeding
A bdominal pain or pain with intercourse
I nfection (abnormal vaginal discharge)
N ot feeling well, fever, chills
S trings lost, shorter or longer
Uterine inflammation, uterine perforation, ectopic pregnancy
Condom – latex inserted to erected penis or lubricated vagina
Adv; gives highest protection against STD – female condom

Alerts:
Disadvantage:
it lessen sexual satisfaction
it gives higher protection in the prevention of STDs

Diaphragm – rubberized dome shaped material inserted to cervix preventing sperm to get to the uterus. REVERSABLE

Ht:
1.) proper hygiene
2.) check for holes before use
3.) must stay in place 6 – 8 hrs after sex
4.) must be refitted especially if without wt change 15 lbs
5.) spermicide – chem. Barrier ex. Foam (most effective), jellies, creams
S/effect: Toxic shock syndrome

Alerts: Should be kept in place for about 6 – 8 hours

Cervical Cap – most durable than diaphragm no need to apply spermicide
C/I: abnormal pap smear

Foams, Jellies, Creams

Surgical Method – BTL , Bilateral Tubal Ligation – can be reversed 20% chance. HT: avoid lifting heavy objects
Vasectomy – cut vas deferense.
HT: >30 ejaculations before safe sex
O – zero sperm count, safe

XI. High Risk Pregnancy

1. Hemorrhagic Disorders

General Management
1.) CBR
2.) Avoid sex
3.) Assess for bleeding (per pad 30 – 40cc) (wt – 1gm =1cc)
4.) Ultrasound to determine integrity of sac
5.) Signs of Hypovolemic shock
6.) Save discharges – for histopathology – to determine if product of conception has been expelled or not

First Trimester Bleeding – abortion or eptopic
A. Abortions – termination of pregnancy before age of viability (before 20 weeks)
Spontaneous Abortion- miscarriage
Cause: 1.) chromosomal alterations
2.) blighted ovum
3.) plasma germ defect

Classifications:

a. Threatened – pregnancy is jeopardized by bleeding and cramping but the cervix is closed
b. Inevitable – moderate bleeding, cramping, tissue protrudes form the cervix (Cervical dilation)
Types:
1.) Complete – all products of conception are expelled. No mgt just emotional support!
2.) Incomplete – Placental and membranes retained. Mgt: D&C
Incompetent cervix – abortion
McDonalds procedure – temporary circlage on cervix
S/E; infection. During delivery, circlage is removed. NSD
Sheridan – permanent surgery cervix. CS

c. Habitual – 3 or more consecutive pregnancies result in abortion usually related to incompetent cervix. Present 2nd trimester
d. Missed – fetus dies; product of conception remain in uterus 4 weeks or longer; signs of pregnancy cease. (-) preg test, scanty dark brown bleeding
Mgt: induced labor with oxytocin or vacuum extraction

5.) Induced Abortion – therapeutic abortion to save life of mom. Double effect choose between lesser evil.

C. Ectopic Pregnancy – occurs when gestation is located outside the uterine cavity. common site: tubal or ampular
Dangerous site - interstitial
Unruptured
Tubal rupture
missed period
abdominal pain within 3 -5 weeks of missed period (maybe generalized or one sided)
scant, dark brown, vaginal bleeding

Nursing care:
Vital signs
Administer IV fluids
Monitor for vaginal bleeding
Monitor I & O
sudden , sharp, severe pain. Unilateral radiating to shoulder.
shoulder pain (indicative of intraperitoneal bleeding that extends to diaphragm and phrenic nerve)
+ Cullen’s Sign – bluish tinged umbilicus – signifies intra peritoneal bleeding
syncope (fainting)
Mgt:
Surgery depending on side
Ovary: oophrectomy
Uterus : hysterectomy


Second trimester bleeding

C. Hydatidiform Mole “bunch or grapes” or gestational trophoblastic disease. – with fertilization. Progressive degeneration of chorionic villi. Recurs.
- gestational anomaly of the placenta consisting of a bunch of clear vesicles. This neoplasm is formed form the selling of the chronic villi and lost nucleus of the fertilized egg. The nucleus of the sperm duplicates, producing a diploid number 46 XX, it grows & enlarges the uterus vary rapidly.
Use: methotrexate to prevent choriocarcinoma
Assessment:
Early signs - vesicles passed thru the vagina
Hyperemesis gravidarium increase HCG
Fundal height
Vaginal bleeding( scant or profuse)
Early in pregnancy
High levels of HCG
Preeclampsia at about 12 weeks
Late signs hypertension before 20th week
Vesicles look like a “ snowstorm” on sonogram
Anemia
Abdominal cramping
Serious complications hyperthyroidism
Pulmonary embolus
Nursing care:
Prepare D&C
Do not give oxytoxic drugs
Teachings:
a. Return for pelvic exams as scheduled for one year to monitoring HCG and assess for enlarged uterus and rising titer could indicative of choriocarcinoma
b. Avoid pregnancy for at least one year
Third Trimester Bleeding “Placenta Anomalies”

D. Placenta Previa – it occurs when the placenta is improperly implanted in the lower uterine segment, sometimes covering the cervical os. Abnormal lower implantation of placenta.
candidate for CS
Sx: frank
Bright red
Painless bleeding
Dx:
Ultrasound
Avoid: sex, IE, enema – may lead to sudden fetal blood loss
Double set up: delivery room may be converted to OR

Assessment:
Engagement (usually has not occurred)
Fetal distress
Presentation ( usually abnormal)
Surgeon – in charge of sign consent, RN as witness
MD explain to patient
complication: sudden fetal blood loss

Nursing Care
NPO
Bed rest
Prepare to induce labor if cervix is ripe
Administer IV

E. Abruptio Placenta – it is the premature separation of the placenta form the implantation site. It usually occurs after the twentieth week of pregnancy.
Outstanding Sx: dark red, painful bleeding, board like or rigid uterus.

Assessment:
Concealed bleeding (retroplacental)
Couvelaire uterus (caused by bleeding into the myometrium)-inability of uterus to contract due to hemorrhage.
Severe abdominal pain
Dropping coagulation factor (a potential for DIC)
Complications:
Sudden fetal blood loss
-placenta previa & vasa previa
Nursing Care:
Infuse IV, prepare to administer blood
Type and crossmatch
Monitor FHR
Insert Foley
Measure blood loss; count pads
Report s/sx of DIC
Monitor v/s for shock
Strict I&O
F. Placenta succenturiata – 1 or 2 more lobes connected to the placenta by a blood vessel may lead to retained placental fragments if vessel is cut.
G. Placenta Circumvalata – fetal side of placenta covered by chorion
H. Placenta Marginata – fold side of chorion reaches just to the edge of placenta
I. Battledore Placenta – cord inserted marginally rather then centrally
J. Placenta Bipartita – placenta divides into 2 lobes
K. Vilamentous Insertion of cord- cord divides into small vessels before it enters the placenta
L. Vasa Previa – velamentous insertion of cord has implanted in cervical OS


2. Hypertensive Disorders

I. Pregnancy Induced Hypertension (PIH)- HPN after 24 wks of pregnancy, solved 6 weeks post partum.

1.) Gestational hypertension - HPN without edema & protenuria H without EP
2.) Pre-eclampsia – HPN with edema & protenuria or albuminuria HE P/A
3.) HELLP syndrome – hemolysis with elevated liver enzymes & low platelet count

II. Transissional Hypertension – HPN between 20 – 24 weeks

III. Chronic or pre-existing Hypertension –HPN before 20 weeks not solved 6 weeks post partum.
Three types of pre-eclampsia
1.) Mild preeclampsia – earliest sign of preeclampsia
a.) increase wt due to edema
b.) BP 140/90
c.) protenuria +1 - +2


2.) Severe preeclampsia
Signs present: cerebral and visual disturbances, epigastric pain due to liver edema and oliguria usually indicates an impending convulsion. BP 160/110 , protenuria +3 - +4

3.) Eclampsia – with seizure! Increase BUN – glomerular damage. Provide safety.

Cause of preeclampsia
1.) idiopathic or unknown common in primi due to 1st exposure to chorionic villi
2.) common in multiple pre (twins) increase exposure to chorionic villi
3.) common to mom with low socioeconomic status due to decrease intake of CHON

Nursing care:
P – romote bed rest to decrease O2 demand, facilitate, sodium excretion, water immersion will cause to urinate.
P- prevent convulsions by nursing measures or seizure precaution
1.) dimly lit room . quiet calm environment
2.) minimal handling – planning procedure
3.) avoid jarring bed

P- prepare the following at bedside
- tongue depressor
- turning to side done AFTER seizure! Observe only! for safely.
E – ensure high protein intake ( 1g/kg/day)
- Na – in moderation

A – anti-hypertensive drug Hydralazine ( Apresoline)
C – convulsion, prevent – Mg So4 – CNS depressant
E – valuate physical parameters for Magnesium sulfate
Magnesium SO4 Toxicity:
1. BP decrease
2. Urine output decrease
3. Resp < 12
4. Patella reflex absent – 1st sigh Mg SO4 toxicity. antidote – Ca gluconate

3.Diabetes Mellitus - absence of insufficient insulin (Islet of Langerhans of pancreas)
Function: of insulin – facilitates transport of glucose to cell
Dx: 1 hr 50gr glucose tolerance test GTT
Normal glucose – 80 – 120 mg/dl < 80 – hypoclycemic
( euglycemia) > 120 - hyperglycemia

3 degrees GTT of > 130 mg/dL
maternal effect DM
1.) Hypo or hyperglycemia – 1st trimester hypo, 2nd – 3rd trim – hyperglycemic
2.) Frequent infection- moniliasis
3.) Polyhydramnios
4.) Dystocia-difficult birth due to abnormalities in fetus or mom.
5.) Insulin requirement, decrease in insulin by 33% in 1st tri; 50% increase insulin at 2nd – 3rd trimester.
Post partum decrease 25% due placenta out.

Fetal effect
1.) hyper & hypoglycemia
2.) macrosomia – large gestational age – baby delivered > 400g or 4kg
3.) preterm birth to prevent stillbirth

Newborn Effect : DM
1.) hyperinsulinism
2.) hypoglycemia
normal glucose in newborn 45 – 55 mg/dL
hypoglycemic < 40 mg/dL
Heel stick test – get blood at heel
Sx:
Hypoglycemia high pitch shrill cry tremors, administer dextrose
3.) hypocalcemia - < 7mg%
Sx:
Calcemia tetany
Trousseau sign
Give calcium gluconate if decrease calcium

Recommendation
Therapeutic abortion
If push through with pregnancy
1.) antibiotic therapy- to prevent sub acute bacterial endocarditis
2.) anticoagulant – heparin doesn’t cross placenta

Class I & II- good progress for vaginal delivery
Class III & IV- poor prognosis, for vaginal delivery, not CS!
NOT lithotomy! High semi-fowlers during delivery. No valsalva maneuver
Regional anesthesia!
Low forcep delivery due to inability to push. It will shorten 2nd stage of labor.

Heart disease
Moms with RHD at childhood
Class I – no limit to physical activity
Class II – slight limitation of activity. Ordinary activity causes fatigue & discomfort.

Recommendation of class I & II
1.) sleep 10 hrs a day
2.) rest 30 minutes & after meal

Class III - moderate limitation of physical activity. Ordinary activity causes discomfort
Recommendation:
1.) early hospitalization by 7 months

Class IV. marked limitation of physical activity. Even at rest there is fatigue & discomfort.
Recommendation: Therapeutic abortion

XII. Intrapartal complications
1. Cesarean Delivery Indications:
a. Multiple gestation
b. Diabetes
c. Active herpes II
d. Severe toxemia
e. Placenta previa
f. Abruptio placenta
g. Prolapse of the cord
h. CPD primary indication
i. Breech presentation
j. Transverse lie

Procedure:

b. Low segment – bikini line type – aesthetic use

VBAC – vaginal birth after CS
INFERTILITY - inability to achieve pregnancy. Within a year of attempting it
Manageable
STERILITY - irreversible
Impotency – inability to have an erection

2 types of infertility
1.) primary – no pregnancy at all
2.) Secondary – 1st pregnancy, no more next preg
test male 1st
more practical & less complicated
need: sperm only
sterile bottle container ( not plastic has chem.)
Sims Huhner test – or post coital test. Procedure: sex 2 hours before test
mom – remains supine 15 min after ejaculation
Normal: cervical mucus must be stretchable 8 – 10 cm with 15 – 20 sperm. If >15 – low sperm count
Best criteria- sperm motility for impotency
Factors: low sperm count
1.) occupation- truck driver
2.) chain smoker
administer: clomid ( chomephine citrate) to induce spermatogenesis
Mgt: GIFT= Gamete Intra Fallopian Transfer for low sperm count
Implant sperm in ampula

1.) Mom: anovulation – no ovulation. Due to increase prolactin – hyperprolactinemia
Administer; parlodel ( Bromocryptice Mesylate)
Action; antihyper prolactineuria
Give mom clomid: action: to induce oogenesis or ovulation
S/E: multiple pregnancy

2.) Tubal Occlusion – tubal blockage – Hx of PID that has scarred tubes
use of IUD
appendicitis (burst) & scarring
= dx: hysterosalphingography – used to determine tubal patency with use of radiopaque material
Mgt: IVF – invitrofertilization (test tube baby)
England 1st test tube baby

To shorten 2nd stage of labor!
1.) fundal pressure
2.) episiotomy
3.) forcep delivery
