[Management of umbilical cord prolapse and neonatal outcomes].

Objective: To evaluate the obstetrical management of umbilical cord prolapse and the neonatal outcomes.

Methods: Retrospective study of 57 prolapses of umbilical cord between 1998 and 2009. Arterial pH of umbilical cord, Apgar score and diagnosis delivery time (DDT) were analyzed.

Results: The incidence of the cord prolapse was of 1.25 for 1000 deliveries. Cord prolapse occurred with the artificial rupture of membranes in 24 cases (42%) out of 57. There were 48 caesarean births. There were three hydramnios and seven cases of twin pregnancy. The mean pH in the umbilical arteries was 7.15 ± 0.13 in 27 cases. The mean Apgar for the 57 newborns was 6 ± 3 at 1 min and 8 ± 3 at 5 min. The mean DDT was 18 ± 8 min (range: 3-44). In 17 cases out of 27, the mean arterial umbilical pH was 7.07 ± 0.09. Fifteen newborns (26%) had a 5-minute Apgar score less than 7 and were admitted in intensive care unit. The mean Apgar score in the nine vaginal deliveries was 8 ± 4 min. In case of cephalic presentations without associated foetal or maternal pathologies there was a tendency of a better pH when the DDT was shorter. In non-cephalic presentations (14 cases), the mean Apgar score was 8 ± 3 at 5 min. The mean pH measured in eight cases was 7.20 ± 0.13 with mean DDT of 20 minutes.

Conclusion: The umbilical cord prolapse remains a serious event for the newborns. The reduction of the DDT in cephalic presentation seems to be correlated to a better neonatal state. The caesarean section is the preferential way of childbirth.
