Intrapartum Period Flashcards
process by which the product of conception are expel from the body
labor
actual birth process
delivery
4Ps in intrapartum factors
- passenger
- pelvis
- power
- psyche
what is the most presenting, important, larget part, and least compressible part of passenger (fetus)?
fetal head
it is the membrane tissues between bones (important for molding)
suture lines
overlapping of cranial bones
molding
suture lines
lies between 2 frontal bones
mitotic / frontal
suture lines
between parietal bones
sagittal
suture lines
between frontal and parietal bones
coronal
fontanels
- lies between frontal, sagittal, and coronal sutures
- diamond in shape
- should be closed at 12-18 month
anterior (large fontanel)
suture lines
between parietal and occipital
lambdoidal
membrane covered spaces at the junction of suture lines
fontanels (bunubunan)
fontanels
- lies between sagittal and labdoidal
- trinagle in shape
- closes at 2-3 months
posterior (small fontanel)
areas of the skull
lies in the posterior (small) fontanel
occiput
areas of the skull
positioned between anterior and posterior fontanel
vertex
areas of the skull
area of the large fontanel
bregma
areas of the skull
brow area
sinciput
transverse diameter
parietal =
bitemporal =
bimastoid =
parietal = 9.25 cm
bitemporal = 8 cm
bimastoid = 7 cm
antero posterior diameter and attitue
parietal =
bitemporal =
bimastoid =
parietal =narrowest, 9.5 cm, full flexion
bitemporal = 12 cm, moderate flexion
bimastoid = widest, 13 cm, poor flexion
relationship of the presenting parts to the maternal pelvis
fetal presentation
fetal presentation
-96% of all presentations
- vertex, face, brows
cephalic
fetal presentation
- buttocks, feet, or both
could be:
a. complete / full (yoga position)
b. frank (U position, buttocks is the presenting part)
c. footling (single foot )
breech
fetal presentation
shoulder (DUUUH)
shoulder
relationship of presenting part to the maternal ischial spine
- expressed in integers
fetal station
fetal station
- freely movable above the ichial spine / pelvic inlet
around -4 to -1
floating
fetal station
- has reached the level of the pelvic inlet
engangement
relationship of presenting part to a specific quadrant of maternal pelvis
fetal position
6 segment of maternal pelvis
right: anterior, transverse, posterior
left: anterior, transverse, posterior
landmark of fetus
occiput
vertex
landmark of fetus
mentum
face
landmark of fetus
sacrum
breech
landmark of fetus
scapula
shoulder
relationship of fetal axis to the maternal axis
fetal lie
fetal lie
- fetal axis is perpendicular / right angle to the maternal axis
transverse lie
fetal lie
- fetal axis is parallel to maternal axis (cephallic or breech)
- most common, 99%
longitudinal lie
> characteristic posture of the fetus inside
a.c.a degree of flexion
relationship of fetal parts to each other in the uterus
fetal attitude
it is the bones structure twhere the fetus pass through during birth
pelvis
types of pelvis
- normal female pelvis
-round inlet
- ideal for vaginal delivery
gynecoid
types of pelvis
-normal male pelvis
-heart shaped inlet
android
types of pelvis
-open like pelvis
- oval inlet
anthropoid
types of pelvis
- flat female pelvis
- transverse oval inlet
platypelloid
