AIMS: To compare neonatal neurological morbidity associated with uterine rupture with morbidity associated with a non-reassuring fetal status. METHODS: We conducted a retrospective cohort analysis. Twenty-one cases of term infants delivered after a symptomatic uterine rupture were analyzed and compared with a randomly selected group of 63 infants born after a non-reassuring fetal heart rate pattern. RESULTS:Prevalence of uterine rupture was 0.058%. Maternal factors and infant general data were similar in both groups. Infants delivered after a uterine rupture had lower Apgar scores at 1 and 5 min, lower umbilical blood pH, and required more advanced resuscitation than infants delivered after a non-reassuring fetal status. Prevalence of hypoxic-ischemic encephalopathy in the uterine rupture group was 33%, compared with 5% in the other group (P<0.01, relative risk 3.7). Four infants in the uterine rupture group (19%) had moderate or severe encephalopathy; all of them had also multisystem dysfunction and an adverse outcome. No infant in the non-reassuring fetal status group showed moderate or severe encephalopathy. CONCLUSIONS: Uterine rupture is a considerable sentinel event that involves a high rate of early and late neurological morbidity in the newborn infant.
