MATERNITY NURSING Prepared by: Fely Rodriguez, RN, RM, MN
ANATOMY EXTERNAL PUDENDA
/ VULVA- includes all structure visible externally from pubis to perineum that includes: 1. 2. 3. 4. 5. 6.
MONS PUBIS LABIA MAJORA LABIA MINORA CLITORIS VESTIBULE PERINEUM
INTERNAL
Measurement: 3 -4 inches between bladder and rectum function: ph 4.5 – 5.5 (acidic doderline bacilli rugae permits considerate stretching without tearing post vaginal canal vascular supply
Main: Internal Iliac Artery Upper third = cervicovaginal branches middle third = inferior vesical artery lower third = middle rectal and internal ppudendal arteries
•
VAGINA
lymphatics
or drains into:
upper- ileac nodes middle- internal ileac nodes lower- inguinal lymph nodes
•
VAGINA
Parts: 2 major unequal parts
2. UTERUS the upper 2/3, triangular portion the lower 1/3, cylindrical portion
Layers
endometrium/mucusal layer/DECIDUA myometrium/muscular layer
perimetrium/serosal layer
2. UTERUS •measurements: • NP- 3 inches long, 2 inches wide, one inch thick • Preg.- 32 cms, 24 cms., 20-24 cms •weight: NP= 50-60 gms • P= 1000 gms (immediately after delivery •capacity : 10 ml – 75 ml cavity {ave. of 30 ml} 5 L at term • 20 L- can hold at this maximum
2. UTERUS •Function: organ of menstruation organ of pregnancy/implantation labor power-powerful contract
Size and Shape of uterus
original n-p shape –pear shape as pregnancy advances by 3rd lunar month-globular S. subsequently uterus
2. UTERUS
increase rapidly by length decrease not width giving-ovoid shape end of 12 weeks-uterus becomes an abdominal organ for it become too large to remain in pelvis
vascular supply
uterine and ovarian arteries
3. FALLOPIAN TUBES/OVIDUCTS
measurements: 8-14 cm./ 4 inches tube Parts: 1. interstitial-insertion in uterine wall 2. isthmus-narrowest portion 2-3 mm 3. ampulla-widest 5-8 mm 4. infundibulum- fimbrae, fingerlike projections Layers: outer longitudinal layer inner circular layer
3. FALLOPIAN TUBES/OVIDUCTS
Function
site of fertilization passageway of ovum from ovaries passageway of sperm from uterus
Note:
5 minutes-sperm as quickly as this reach site of fertilization from time of ejaculation 12-24h average-mature ovum is capable being fertilized after ovulation
4. OVARIES
FUNCTION 1. cardinal and primary function 2. endocrine PARTS 1. cortex 2. medulla Almond shape mittleschermz-pain during ovulation due to rupture of follicle, fluid and blood escape into peritoneum and irritates Lifetime history of germ cell maturation
Testis semineferous gland interstitial Epididymis-stores where it matures and it becomes motile vas deferens- passage of sperm prostate gland secret alkaline fluid for sperm to swim cm 2.5-3.5 glandular structure that surrounds the neck of bladder and urethra Bulburethra/ cowpers gland
72 hours- normal lifespan of sperm outside male’s body or after ejaculation to woman genital in normal men, semen volume and density decreases when ejaculation occurs more often than 48hrs right testis is lower than left because the large liver wide space to occupy and pushes it composition of semen 1. Sperm a. head b. body c. tail 2. secretions by seminal vesicle 3. prostate gland 4. cowper’s/bulbourethral gland
PHYSIOLOGY –MENSTRUATION – periodic discharge of bloody fluid from uterus occurring at more or less regular intervals during the life of a woman for puberty to menopause Menstruation E stim
and P low
Hypo to release GnRH {FSHRF&LHRF}
release
FSHRF triggers
APG-FSH
acts
on follicles of ovary, but only one will grow and develop GF-growing and developing primoidial follicle called Graafian follicle as
GF grows and develop produces ESTROGEN
in response to increase estrogen
lining of uterus starts to thicken
cervical glands produce sticky, cloudy, flaky mucus discharge giving a woman sticky sensation around the vagina
as
GF full matures E is at its peak and man levels of estrogen
HYPO stop prod. FSHRF-APG-Stop FSH simultaneously produce LHRF-APG- LH
2. 3.
acts
on matured GF causing it to rupture and release process
called ovulation
the
ruptured follicle becomes a yellow body called CORPUS LUTEUM produces and release progesterone
supports
spongy,
further growth of endometrium becomes
very thick, rich in mucus and b.v (vascular and tortous) making is a perfect bed for possible implantation
P
reach its peak and no fertilization stimu. – HYPO- to stop LHRF APG
stops LH Causes the CL to degenerate in 14 days as its normal life span,a drop in Pragesterone causes the Shedding
or sloughing of endometrial lining= MENSTRUATION
Success of menstruation depends on different 4 body structure involved and its interaction 1. HYPO FSHRF & LHRF 2. APG FSH & LH 3. OVARY E/P 4. UTERUS
Phases of Menstrual Cycle 1. 2. 3.

EXERCISE Pelvic Rock=low backache Kegel’s = pelvic pressure / congestion Walking Modified Knee Chest exercise = relieves discomforts of hemorrhoids, cramps in the thighs & buttocks Squatting/Tailor Sitting – strenghtens perineal muscles
For CGFNS : NST vs CST, AMNIOCENTESIS, RUBELLA TITIER NST
or FAD TEST - determines fetal fetal response to every fetal movement. An increase of 15 bpm is expected @ each movement means REACTIVE result. Mothers who has been sedated or was not able to take a good meal prior to the NST may yield a false Non Reactive result & not necessarily mean a Non re assuring fetal well being.
DIFFERENCE OF FALSE LABOR
From
TRUE LABOR PAINS
Assessment tool/criteria” 1. Uterine contraction
Irregular u.c. in terms of duration, interval& freq.
Becoming regular w increasing intensity
2.Location of pain
Confined in the abdomen
Radiates at the lumbosacral region (back)
3.ambulation
Decreases uterine contraction
Worsens uterine contraction
4. Sedation
Relieves of the pain

Cranial bones 1. frontal 2. occiput 3. parietal Membrane spaces/suture lines - important they allow bones to move and overlap and change shape to fit in birth canal called molding 1. sagittal suture-membranes interspace which join 2 parietal bones 2. coronal suture- frontal bone and 2 parietal bones 3. lamboidal- occiput and parietal Fontanelles- membrane covered spaces at the junction of the main suture line

Nursing Responsibilities
Check BP – X if 90/60 Given after bb out
Possible Complications
Uterine rupture
Check BP –X if 130/90 Given only after placental delivery Placental entrapment leads to massive bleeding
4 Stage of Labor th
Known
as the Degrees of Laceration: 1st – vaginal skin (Fourchette) 2nd – vag.skin muscles, & mucosa 3rd – 2nd degree + extends into the external anal sphincter 4th - 2nd degree + rectal mucosa
LOCATION
OF FUNDUS:
Immediately after delivery
- slightly above the level of umbilicus 1st 24 hrs (12-24 hrs)- @ the level of umbilicus PPD1 - 1 fingerbreadth below the umbilicus
PPD10
The involution of the uterus subsides @ 1 fingerbreadth per day. - (-) Palpate coz its behind the symphysis pubis
LOCHIA COMPOSITION: All but one is a normal composition of lochia: a. shreds of decidua b. small clotted blood with mucus c. WBC d. bacteria e. amniotic fluid
