Premature rupture of the membranes (PROM) in the previable gestation is frequently associated with fetal or neonatal death. Passive expectant management is successful in only a small minority of cases. Women presenting with PROM at < or = 27 weeks' gestation were treated with tocolysis and prophylactic antibiotics and delivered electively for lung maturity. The corrected perinatal survival was > 92%. The mean latency phase was 21.6 days (+/- 18.12 SD). Twenty-one percent of patients presented in labor; the mean latency phase for this subgroup was 14.4 (+/- 8.54) days. Nineteen patients (79%) had a latency phase > 7 days, and 14 (58%) had a latency phase > 14 days. Thirty-nine percent of infants required < 48 hours of mechanical ventilation. Six infants were delivered with intraventricular hemorrhage; in all cases it was grade 1 or 2. There were three (12.5%) postpartum infections and three septic neonates. Active expectant management using tocolysis and prophylactic antibiotics was associated with a prolonged latency phase, low infectious morbidity and good neonatal outcome.

An 18-year-old woman developed disseminated blastomycosis in the 30th week of pregnancy. She was treated with amphotericin-B. Simultaneous maternal-infant blood levels at birth were 1.9 and 1.3 micrograms/mL, respectively. The amphotericin-B level in the amniotic fluid was 0.3 microgram/mL at delivery. The infant was normal and without ill effects from either the blastomycosis or the amphotericin-B. The skin lesions and pulmonary infiltrates in the mother improved rapidly, without unexpected side effects from the therapy. The limited experience with amphotericin-B indicates that it is both well tolerated and effective in this clinical situation.
