Labor and Birth Process Flashcards
Uterine contractions have two main functions…
- to dilate the cervix
2. to push the fetus through the birth canal
effacement
the enhanced collagen breakdown that was previously inhibited by progesterone.
Lightening
when the fetal presenting part begins to descent into the true pelvis…the uterus lowers and moves into a more anterior position.
Bloody shows
the mucus plug expels and ruptures some cervical capillaries- producing a pink-tinged secretions.
Braxton Hicks contractions
Occur primarily in the abdomen and groin and gradually spread downward before relaxing.
True Labor Contractions
normally felt in the lower back
Braxton Hicks contractions aid..
in moving the cervix from a posterior position to an anterior position, they help to soften and ripen the cervix.
How long do Braxton Hicks contractions normally last
from 30 seconds to 2 minutes
As birth nears, the uterus becomes more sensitive to oxytocin the
frequency and intensity of these contractions increase
Prelabor rupture of membranes (PROM)
rupture of membranes with loss of amniotic fluid prior to the onset of labor
Pregnancy last approx.
10 lunar months, 9 calendar months, 40 weeks, or 280 days
the length of pregancy is computed from
the first day of the LNMP
Nagele’s Rule is used to
calculate EDD
Gravida
number of times pregnant including the present pregnancy regardless of the outcome
para
number of deliveries at 20 weeks or greater whether the newborn is born dead or alive
GTPAL
method used for recording a woman’s pregnancy history
GTPAL
G-Gravida T- Term pregnancies P- Preterm deliveries A- Abortions L- Number of children living
First trimester
From the firs day of LMP through 12 weeks
Second trimester
13 weeks through 27 weeks
