Topic 7: Labor Flashcards
this refers to series of events when the product of conception is expelled out from the woman’s body
labor
4 theories of labor
uterine stretch theory oxytocin and prostaglandin progesterone deprivation theory prostaglandin theory placental aging theory
theory: works together to inhibit calium binding in muscle cells raising intracellular calcium thus activating contractions
oxytocin and prostaglandin
theory:
it is known that uterus is a hollow organ. And when an hollow organ reaches its peak of stretchability, it tries to contract to expel its content. with the help of the prostaglandin, contraction of the uterus would indicate a sign of labor
uterine stretch theory
theory:
this theory says that this hormone is responisble for stimulating myometrium or the muscle of the uterus to contract, thus labor begins
prostaglandin theory
theory:
when placenta reaches its peak of performance. Its function starts to degenerate due to the decrease of the homrones estrogen and progesterone. Which triggers the labor
placental aging theory
theory:
a decrease in progesterone causes uterine changes, thus labor pains occur. Progesterone is known to inhibit uterus mobility, and with the deprivation of this hormone it causes changes.
Progesterone deprivation theory

this refers to the setting of the fetal presenting into ischial spine.
engagement

station
if the head is in the ischial spine, what is the station?
0
station of crowning
+3 / +4
station of floating
-3/-4
this refers to the opening of the cervical os which is express in centimeters
dilatation
artificial rupturing on the bag of membrane is called
amniotomy
thinning of the vaginal rugae which is expressed in percentage is called
effacement
site of episiotomy
perineum
diamong shape indention that will close at 18 months; also referred to as BREGMA
anterior fontanelle
will close immediately after delivery but on some cases, it will close after 3 months
posterior fontanelle
the degree of flexion / extension the fetus assumes
fetal attitude
only applicable for cephalic
this is the relationship of the long axis of the fetus to the long axis of the mother (transverse, vertical)
fetal lie
this refers to the body part that will first contact with the cervix
presentation
diffirent types of breech
