About

Cesarean delivery is defined as fetal birth through incisions in the abdominal wall and the uterine wall. This definition does not include removal of the fetus from the abdominal cavity in the case of uterine rupture or in the case of an abdominal pregnancy The guidelines of the Royal College of Obstetricians and Gynaecologists on caesarean section recommend a slow intravenous bolus dose of 5 IU of oxytocin after delivery of the infant. Intravenous oxytocin has a short half life (4-10 minutes); therefore the potential advantage of an oxytocin infusion at caesarean section is in maintaining uterine contractility throughout the surgical procedure and immediate postpartum period, when most primary haemorrhage occurs
