Objective: The purpose of this study was to assess whether the duration of labor has any effect on the occurrence of cerebral white-matter damage in very preterm infants who are delivered in the presence of intrauterine infection. Study design: From a cohort of infants who were born spontaneously at < 32 weeks of gestation for whom placental information was available and who survived 7 days from birth, 126 infants had clinical, laboratory, or histologic evidence of intrauterine infection. Among them, variables were compared between those infants with white-matter damage (defined as intraventricular hemorrhage grade 3 plus, periventricular leukomalacia, or ventriculomegaly not associated with hydrocephaly [n = 13]) and those infants without it (n = 113). Comparisons were made with t test, chi-squared test, and survival analysis; a probability value of <.05 was considered significant. Results: There were no differences between the 2 groups in gestational age at delivery and rates of labor or cesarean delivery. Duration of active labor (66 +/- 45 minutes vs 88 +/- 75 minutes; P = .49) and of clinical chorioamnionitis (310 +/- 186 minutes vs 529 +/- 544 minutes; P =.44) were similar in cases with and without neonatal white-matter damage. Conclusion: In 126 infants who were born at < 32 weeks of gestation with intrauterine infection, we found no correlation between the duration of labor or clinical chorioamnionitis and neonatal white-matter damage.

Abstract

Objective: The purpose of this study was to assess whether the duration of labor has any effect on the occurrence of cerebral white-matter damage in very preterm infants who are delivered in the presence of intrauterine infection. Study design: From a cohort of infants who were born spontaneously at < 32 weeks of gestation for whom placental information was available and who survived 7 days from birth, 126 infants had clinical, laboratory, or histologic evidence of intrauterine infection. Among them, variables were compared between those infants with white-matter damage (defined as intraventricular hemorrhage grade 3 plus, periventricular leukomalacia, or ventriculomegaly not associated with hydrocephaly [n = 13]) and those infants without it (n = 113). Comparisons were made with t test, chi-squared test, and survival analysis; a probability value of <.05 was considered significant. Results: There were no differences between the 2 groups in gestational age at delivery and rates of labor or cesarean delivery. Duration of active labor (66 +/- 45 minutes vs 88 +/- 75 minutes; P = .49) and of clinical chorioamnionitis (310 +/- 186 minutes vs 529 +/- 544 minutes; P =.44) were similar in cases with and without neonatal white-matter damage. Conclusion: In 126 infants who were born at < 32 weeks of gestation with intrauterine infection, we found no correlation between the duration of labor or clinical chorioamnionitis and neonatal white-matter damage.
