Outcome of term gestation neonates whose mothers received intrapartum antibiotics for suspected chorioamnionitis.
Intrapartum antibiotics are commonly given to women suspected of having chorioamnionitis. However, there is no consensus regarding management of their babies. To date, there are no data concerning the clinical courses and outcomes of term gestation, "pretreated" neonates. We performed a retrospective review to assess the clinical courses of such infants. From 1987 to 1989, chorioamnionitis was diagnosed in 123 women, 102 of whom received intrapartum antibiotics. Of the 86 term gestation infants born to women in the latter group, 63 were completely asymptomatic. When compared with these neonates, the 23 symptomatic infants were more likely to have lower median 1 and 5 minute Apgar scores (3 vs 8 and 7 vs 9, respectively; p < 0.0001), higher immature:mature neutrophil ratios on their initial complete blood counts (0.48 vs 0.24; p = 0.0003), and positive urine antigen studies for group B Streptococcus in the presence of negative blood cultures (4 vs 2; p = 0.042). The intrapartum courses of those infants destined to be symptomatic were more likely to be complicated by fetal tachycardia (p = 0.049) and malodorous amniotic fluid (p = 0.005). Since more than 95% of asymptomatic, pretreated, term gestation neonates have a benign clinical course, aggressive evaluation and management of these infants may not be necessary.
