Preterm Labor
? Labor before 37 weeks
? Sterile speculum and bimanual
exam
? Risk factors: PROM, abruption,
cocaine, amphetamines,
multiple births, infection
? Admit, bed rest, tocolytics
(terbutaline)
126

127
Premature Rupture of Membrane (PROM)
? Rupture prior to onset of labor
? Digital pelvic exams associated with
increased frequency
? Limit digital exams and use sterile gloves

? Complications: Premature labor, prolapsed
cord, infection (chorioamnionitis)
? Admit
128
129
Umbilical Cord Prolapse
? High perinatal mortality
? Knee-to-chest position

Impede delivery and elevate presenting part
130
Amniotic Fluid Embolism
? 2nd and 3rd trimesters

resulting in an immunologic maternal response,
simulating anaphylaxis
? Rare
? Occurs with labor, C-section, abruptio placentae,
abortion, amniocentesis, trauma
? Sudden cardiovascular col apse, usual y soon
after delivery, seizures
? Shock, dyspnea, hypoxemia, ARDS, DIC
? High mortality (50% at one hour); supportive care
131
Postpartum Hemorrhage (1)
? Uterine atony
?Most common in first 24 hrs
?Enlarged "doughy" uterus
?Risks: Prolonged or precipitous labor,
multiparity, multiple gestations

? Uterine rupture
?Prior C-section, trauma, cocaine, high doses of
oxytocin
?Shock, bleeding, absent heart tones, tender
boggy uterus that expands
?Fluid resuscitation, immediate C-section
132
Postpartum Hemorrhage (2)
? Retained products of conception
?Early or delayed postpartum hemorrhage
?Sudden, brisk, painless bleeding
?Globular, firm uterus
?Oxytocin, D&C, fluid resuscitation
? Laceration of lower genital tract
? Coagulopathy
? Uterine inversion
?Excessive traction on umbilical cord
?Vaginal mass, uterus not palpable on exam
?Obstetrical emergency (IV, O2, tocolytic drugs)
?Do not separate placenta
133
?Manual reduction or emergent laparotomy
Trauma in Pregnancy
(see also Trauma lecture)
? Initial trauma care same as in non-pregnant
? RhoGAM if Rh negative and abdominal trauma
? No radiologic test should be withheld if needed for
maternal evaluation
? Fetal monitoring >20 weeks
?Minimum of 4 hours
?Signs of fetal distress
?>8 contractions/hr suggest abruption
? Kleihauer-Betke test (controversial)
? For hypotension: Turn on left side (displace
uterus off IVC), fluid bolus
Maternal stabilization is the most important
factor in determining fetal survival
134
Peri-mortem C-Section
? Maternal cardiopulmonary arrest
? Indicators of fetal survival
?Cause of maternal death
?Quality of CPR
?Gestational age (>24 weeks)
?Arrest to delivery time (survival unlikely after 20
minutes)
? Vertical abdominal and uterine incision
135
Endometritis
? Risk factors: C-section, PROM, prolonged labor,
chorioamnionitis, multiple exams, internal
monitoring
? Fever, abdominal pain, foul-smel ing lochia
? Usual y polymicrobial
? Admit, broad spectrum IV antibiotics
Mastitis/Breast Abscess
? Pain, erythema, fever, edema
? Engorged duct becomes blocked, then
infected
? Staphylococcal infection
? Continue breast feeding
136
? Antibiotics (dicloxacil in, cephalexin) or I&D
