Prolonged pregnancy, incidence and morbidity

Abstract

Abstract Background The classic term for a pregnancy is between 37 and 42 weeks of amenorrhea. In fact, the literature has shown that exceeding the term (LD, 42WG) is the cause of many maternal-fetal complications despite close monitoring and appropriate management. A new rigorous and adapted management is essential in view of the materno-fetal prognosis. Objectives To describe the complications and risks associated with exceeded pregnancies and to propose a new strategy indicating an appropriate course of action. Patients and Methods This is a retrospective study of 50 women who gave birth at 42 WG or more at the Maternity of the Farhat Hached University Hospital Center in Sousse. Results the average age of our patients was 30.56 years old, 70% of which were primiparous, 82% of our patients were monitored between 41 and 42 WG. Fetal complications demonstrated in our results were increased by macrosomia in 54% of cases, pathological FHR during labor in 48% of cases, fetal distress in 26% of cases. In addition, maternal complications were increased by cesarean delivery in 48% of cases, perineal tears in 40% of cases and forceps delivery in 20% of cases. Conclusions By comparing the expectation under supervision to induction of labour at 41WG, we concluded that induction of labour reduces maternal-fetal outcomes in a remarkable way. A new management including systematic induction of labour at 41 WG is essential to prevent complications and guarantee a reassuring maternal-fetal prognosis. Key messages Exceeding the classic term for a pregnancy may cause maternal and fetal complications. A new management including systematic induction of labour at 41 WG is essential to prevent complications and guarantee a reassuring maternal-fetal prognosis.
