Vaginal delivery compared with caesarean section in early preterm breech delivery: a comparison of long term outcome.

OBJECTIVE

To determine the optimum mode of delivery of the early preterm fetus in breech presentation.

DESIGN

Retrospective comparison of two cohorts of preterm breech fetus.

SETTING

Two tertiary care centres: at one centre the preferred management for preterm breech presentation was vaginal delivery; at the other centre, the preferred method was caesarean section.

POPULATION: All singleton infants delivered after breech presentation from 1984 through 1989, at a gestational age of 26 to 31 weeks. Those with lethal congenital abnormalities, placenta praevia, placental abruption, fetal death or fetal distress before the onset of labour were excluded.

MAIN OUTCOME MEASURES: Survival without disability or handicap documented at two years corrected age. The influence of a number of relevant variables on this outcome was assessed by logistic regression analysis.

RESULTS

There was no difference in survival without disability or handicap between the centres (odds ratio 1.5, 95% CI 0.6-3.9 vaginal delivery compared with caesarean section). Survival without disability or handicap was positively influenced by increasing birthweight and corticosteroids > 24 h before birth, and negatively influenced by footling presentation.

CONCLUSION

A policy of caesarean section for early preterm (26-31 weeks) breech delivery is not associated with increased survival without disability or handicap.
