Caesarean delivery and outcome in very low birthweight infants.

ABSTRACT

OBJECTIVE: To determine the relationship between mode of delivery, intraventricular haemorrhage (IVH), and mortality in very low birthweight (VLBW) infants. STUDY DESIGN: A historical cohort study of infants admitted to a single level III neonatal intensive care unit during a five-year period. Infants < 1500 g born by caesarean delivery (n = 400) were compared to those born by vaginal delivery (n = 305). RESULTS: After controlling for potential confounding variables including gestational age, fetal presentation, and multiple birth, caesarean delivery was not associated with a decreased odds of IVH (odds ratio 1.2, 95% CI 0.7-2.0), severe IVH (1.9, 0.9-4.0), or mortality (1.2, 0.6-2.4). CONCLUSIONS: In our population of very low birthweight infants, caesarean delivery is not associated with a decreased risk for mortality or intraventricular haemorrhage.
