Objective: To determine the effects of clinical chorioamnionitis on neonatal morbidity and mortality in very low birth weight infants.

Methods: This was an observational cohort analysis of all singleton live-born infants weighing 500-1500 g at 24 weeks' or greater gestational age and born between 1988 and 1996 at Parkland Memorial Hospital, Dallas, Texas.

Multiple logistic regression analysis was used to adjust for outcomes of interest.

Results: Ninety-five of 1367 very low birth weight infants (7%) were exposed to chorioamnionitis. Neonatal sepsis, respiratory distress syndrome, seizure in the first 24 hours of life, intraventricular hemorrhage (grade 3 or 4), and periventricular leukomalacia …
