1

Definition of PROM

Premature Rupture of membranes = spontaneous rupture before labor

2

Define PPROM

Premature (GA

3

When to suspect chorioamnionitis in pt with PROM

Fever & one other thing (maternal tachycardia, fetal tachycardia, maternal leukocytosis > 15K, uterine tenderness, or foul smelling discharge)

4

What GA age for active labor mgt rather than expectant mgt in pre-term labor

34+ wks or proven fetal lung maturity

5

Risk factors for placental abruption

HTN (chronic, gestational, preeclampsia), Prior placental abruption, Trauma, Tobacco use, Cocaine, PROM, multiple gestation, multiple parity

6

Drugs used for tocolytics

Nifedipine, Terbutaline, Ritodrine, MgSO4, Indomethacin

7

Reversal agent for Mg toxicity

Calcium gluconate

8

Mgt pre-term labor at 33 wks & 3 days v. 34 & 3

GBS PPx in both cases; 33 - Tocolysis so can use steroids, then after 48 hrs, Active mgt ; 34 - Active mgt

9

Components biophysical profile for fetal well being

Fetal tone, breathing, movement, AFI, Nonstress test (HR accelerations)

10

Compare appearance of early, late, and variable decelerations & ddx

EARLY - begin & end w/ uterine contraction (head compression) ; LATE - begin & end after (uteroplacental insufficiency, hypoxia); VARIABLE - begin & end inconsistently, V-shaped (may or may not be a sign of fetal distress, umbilical cord compression)

11

Define Oligohydramnios

AFI

12

Define Polyhydramnios

AFI > 25

13

Classic s/sx Mg toxicity

Hyporeflexia (decreased DTRs), Respiratory depression/arrest (possible pleural effusion also) Cardiac arrest

14

Tests used to confirm rupture of membranes

Amnionic pooling in vaginal vault on speculum exam can, Fern test, or Nitralizine blue test

15

W/u Infertility for couple

Semen analysis, Eval anovulatory cycles (menstrual hx, basal body temp monitoring, home urinary ovulation test, postovulation serum progesterone, endomentrial bx on day 26), hysterosalpingogram
