Obésité maternelle en cas de grossesse prolongée : mode de mise en travail, accouchement et issues materno-fœtales

Abstract : Introduction. Obesity is currently not considered as a medical indication for induced labor in prolonged pregnancy. Few data exist regarding labor and complications in prolonged pregnancy in case of obesity in expectative management after 41 weeks of gestation. The aim of our study was to evaluate labor and mode of delivery, fetal and maternal outcomes in prolonged pregnancy in patients with normal BMI compared with obese ones. Material and Method. It was a retrospective study with patients delivered in case of prolonged pregnancy (> 41 weeks of gestation, 287 days) with singleton pregnancy, cephalic presentation, between the first of January 2002 and December 31, 2018 in CHU CAEN’s maternity. Characteristics of the patients were compared in each class of BMI in uni- and multivariate analysis with regression logistics models. Results. 9159 patients were included. Term of birth and spontaneous labor calculated rates were significatively different in case of obesity. The adjusted odds ratio for induced labor in obesity class III was 1, 73 [1.13-2.66], 3.39 [2.04-5.63] for an emergency cesarean section and 1.78 [1.06-2.99] for neonatal morbidity and mortality. Conclusion. The morbid obese patients do not belong to a low risk group when pregnancy is prolonged. Systematic induction of labor in case of morbid obesity would seem to be justified.
