“…The principal endpoint was a composite outcome, named “composite intraoperative adverse event,” defined by any intraoperative adverse event, including: classical uterine incision (because the use of classical incision leads to a cesarean delivery in the next pregnancy and therefore an increase in the global maternal morbidity rate), transplacental incision, difficulty in fetal extraction, postpartum hemorrhage defined by blood loss ≥500 mL [as defined by the World Health Organization and the French clinical guidelines for postpartum hemorrhages or need for transfusion (indication based on clinical and hematological signs, according to French guidelines ], and any injury of adjacent organs (gastrointestinal, urological or vascular). In the surgical reports at our institution, operators systematically and explicitly mention transplacental incisions, any difficulty in fetal extraction, and quantification of blood loss (assessed by weighing dressings and measuring the blood collected by intraoperative aspiration).…”
