Intrapartum Flashcards
face presentation with chin towards mother’s symphysis
mentum anterior (MA)
face presentation with chin towards mother’s perineum
mentum posterior (MP)
face presentation that makes vaginal birth very unlikely
mentum posterior (MP)
inlet with a short anteroposterior diameter and a wide transverse diameter is characteristic of this pelvic type
platypelloid
first portion of the fetus to enter to pelvis is the:
presentation
occurs as the result of the untwisting of the neck after birth of the head
Restitution
positional changes the fetus undergoes to accommodate itself to the maternal pelvis
mechanisms of labor
BPD has passed through the inlet
engagement
top of the head is at the level of the ischial spines
engagement
To determine the position of the fetus you would, identify the:
sagittal suture
Three types of presentation:
breech, shoulder, cephalic
evidence is conflicting on whether epidurals increase risk of:
C/S
___-___% of women with epidurals develop fevers
11-14%
According to Friedman, active labor is defined as the point when:
rate of cervical dilation increases sharply
According to Friedman, prolonged latent phase labor is defined as > ___ hrs in nulliparous and > ___ hrs multiparous women
> 20 hrs in nulliparous and > 14 hrs multiparous women
Active labor begins when the:
RATE of cervical dilation sharply increases.
medication usually used for early labor rest since other medications such as sleeping pills have no pain relieving properties.
Narcotic analgesics (morphine)
Friedman’s criteria for normal latent phase for nulliparas
< 20 hrs
Friedman’s criteria for normal active phase for nulliparas
1.2 cm/hr
Friedman’s criteria for normal latent phase for multiparas
< 14 hrs
Friedman’s criteria for normal active phase for multiparas
1.5 cm/hr
Friedman’s criteria for arrest of 1st stage (latent + active) of labor
no progress x 2 hrs
Friedman’s criteria for normal 2nd stage for nulliparas
1 cm/hr descent
Friedman’s criteria for normal 2nd stage for multiparas
2 cm/hr descent
Friedman’s criteria for arrest of 2nd stage of labor
no progress x 1 hr
Contemporary research normal progress of active labor
0.5 cm/hr
Contemporary research on diagnosing and managing slow labor does not provide clear recommendations for:
appropriate timing of interventions
narcotic used in labor with the longest half-life
Demerol
reflex that results in a surge of oxytocin that enhances contraction strength and pushing effectiveness in second stage labor
Ferguson Reflex
evidence-based technique for perineal management during birth that decreases or minimizes genital tract trauma is:
working with the woman to facilitate a gentle, controlled birth of the baby.
prenatal perineal massage will reduce risk of genital tract trauma…T or F?
true
max dose of Hemabate during severe PPH
8 doses q15 min
Pit should never be given IV because:
it can cause severe hypotension

250 mcg IM
1st line medication for PPH
Pitocin
Pitocin can cause this adverse effect
water intoxication
