Intrapartum Assessment/Stages Chap 8 Flashcards
intrapartum
onset of labor to delivery of placenta
lightening
fetus moving down to pelvis causing moms to pee more
braxton hicks contractions
contractions that dont dilate cervix or change uterus
nesting
mom cleans house, organizes
episiotomy
purposeful surgical cut at perineum
laceration
tear from stretching of uterus/vagina/cervix
maternal labor triggers
stretching of uterine muscles, estrogen/progesterone changes, oxytocin/prostoglandin release
fetal labor triggers
fetal cortisol changes, old placenta, oxytocin, prostaglandin increase contractions
factors affecting labor
powers, passage, passenger, psyche, position
powers
uterine contractions caused by oxytocin releasal
passage
pelvis and birth canal
gynecoid pelvis
heart shaped most optimal for birthing
android pelvis
more heart shaped that limits posterior pelvis for accommodating heart
anthropoid pelvis
narrow oval shaped and hard for baby to pass
platypelloid pelvis
horizontal oval hard for delivery
effacement
shortening and thinning of cervix expressed in percentages
dilation
widening of cervical opening from less than 1 cm to 1o cm
-3 to 0
head above ischial spine
0
narrowest point and head at ischial spine
+1 to +3
head below ischial spine
passenger
fetus
relationship of passenger vs passage includes
size of head, attitude, fetal lie, presentation, position, size
fetal skull
head molds to allow skull to fit through birth canal
fetal attitude
relationship of fetal parts to one another
general flexion
back of fetus is rounded, chin to chest, thighs flexed on abdomen, legs flexed at knees
deviations from normal flexion
difficulties with labor and birth
fetal lie
the relation of long axis of fetus to moms long axis
longitudinal lie
head down butt up
