The purpose of this study was to determine the short-term outcome of newborns less than 30 weeks gestation when there is definite placental histologic chorioamnionitis. A retrospective analysis was performed of records of all neonates delivered at our institution from January 1989 through January 1999. This information was retrieved from our perinatal database and pathology database. The population was stratified according to the presence or absence of histologic chorloamnionitis. Statistical analysis was performed using student t-test and Mann-Whitney method. Logistic regression was used to control for potential confounding variables. There were 392 neonates less than 30 weeks gestation delivered during this time period. Complete placental histology was available for 342 patients (87.4%). Histologic chorloamnionitis was identified in 140 (40.9%) cases. Those with histologic chorloamnionitis delivered sooner (26.3 versus 27.5 weeks), were of lower birth weight (920.1 versus 1029.8 g), and had lower 5-minute Apgarscores. Neonatal septicaemia and pneumonia were strongly associated with underlying histologic chorioamnionitis. There was a significant reduction in the incidence of respiratory distress syndrome (RDS) when histologic chorioamnionitis was present. Severe histologic chorioamnionitis increases the risk of premature delivery and is strongly associated with neonatal sepsis. There is a significant reduction in the incidence of RDS and neonatal mortality.
