[Breech presentation at term: evolution of French practices and an analysis of neonatal results in regards to obstetrical management of breech presentation, from AUDIPOG Database].

OBJECTIVES

To describe the evolution of medical practices in breech presentation at term and to compare early neonatal complications according to initial obstetrical decision on the type of delivery.

METHODS

71919 pregnancies are included in the AUDIPOG Database from 1994 to 2000. Among this cohort, pregnant women with a singleton in breech, at term were selected which represented 2136 women after the exclusion of in utero deaths and medical abortions. The first outcome was global criteria of severe early neonatal complications ("death during per or immediate post partum or transfer of the newborns to an intensive care or surgery unit"). The size of the sample authorized a power of 90%.

RESULTS

The rate of cesarean section before labor was 40%. We found 2.3% of early neonatal complications in the group in which labor was accepted vs. 1.9% in the group with cesarean section performed before labor (p>0.05). After having taken into account prognostic factors, we do not see a significant difference for the risk of neonatal complications between the two groups (OR=1.33; 95% CI: 0.63-2.80).

CONCLUSION

The analysis of the AUDIPOG Database describes the French obstetrical practice in breech presentation at term. We do not find a different risk in morbi-mortality as regards to the initial obstetrical choice regarding the type of delivery, but the absence of randomization in our study does not authorize a strong medical evidence to guide national recommendations.
