Factors associated with adverse perinatal outcomes for term breech fetuses with planned vaginal delivery

Abstract

Objective: We sought to identify factors associated with adverse perinatal outcomes (APO) among term breech neonates with planned vaginal deliveries.

Study design: We conducted univariable and multilevel multivariable analysis of the data collected in the multicenter prospective observational study PREsentation et MODe d'Accouchement (PREMODA) in women with planned vaginal delivery giving birth to singleton term breech babies. The end point was a composite set of APO.

Results: Of 2502 women with planned vaginal delivery recruited in the 174 participating centers, 1772 (71%) delivered vaginally. Adverse outcomes were observed in 165 cases (6.59%). After adjustment, the factors associated with them were geographic origin, gestational age <39 weeks at birth, birthweight <10th percentile, and annual number of maternity unit births <1500.

Conclusion: When strict conditions governed the selection of delivery route and management of labor was rigorous, APO were not associated with any prenatal or peripartum obstetric factors.
