“…Active management of the third stage of labor reduces the risk of postpartum uterine atony, and includes prophylactic oxytocin administration with delivery, vigorous fundal massage lasting at least 15 seconds, and controlled cord traction to deliver the placenta. 55 Oxytocin is the preferred first-line uterotonic for both prophylaxis and treatment of postpartum hemorrhage, because it is clearly shown to decrease blood loss during the third stage of labor and decreases need for additional uterotonics, 55,56 even after prolonged oxytocin infusions for the induction or augmentation of labor.
