10: Normal Labor & Delivery Flashcards
labor
progressive cervical dilation due to regular uterine contractions
braxton hicks contractions
irregular contractions without cervical change, AKA false labor
classic female pelvis shape
gynecoid
two pelvic shapes that are good for delivery and two that are poor for delivery
good: gynecoid, anthropoid
poor: android, platypoid
what position is the fetal head in with the four different types of pelvis
- gynecoid: generally in OA position
- anthropoid: OP position
- android: OP position
- platypelloid: transverse diameter
diagonal conjugate of the pelvis + adequate measurement for delivery
inferior portion of pubic symphysis -> sacral promontory (11.5cm+ is adequate)
obstetric conjugate of the pelvis
diagonal conjugate - 2cm; narrowest distance through which the fetal head must pass
two things to assess when measuring pelvic outlet + adequate measurements of them
- between ischial tuberosities (8.5+ cm)
2. infrapubic angle (angles at which inferior pubic rami meet) (>90 degrees)
four maneuvers of the Leopold maneuver
- palpate fundus: feel for head vs buttocks
- palpate for spine
- palpate what is presenting in pelvis
- palpate for cephalic prominence
indications of episiotomy
likelihood of spontaneous lac is high
modified ritgen maneuver
fingers of right hand extend head while counterpressur is applied to occiput by left hand
induction vs augmentation of labor
- induction: starting labor artificially
2. augmentation: labor has already started, but artificially stimulating it
