The document discusses active management of the third stage of labor. The third stage of labor occurs from childbirth until delivery of the placenta, which typically takes 5-15 minutes but is considered prolonged after 30 minutes. Most cases of postpartum hemorrhage (PPH) occur during the third stage. Active management consists of interventions like uterotonic drugs, controlled cord traction, and uterine massage to speed placental delivery and prevent PPH by ensuring uterine contraction. It has advantages of shorter third stage and lower PPH risk but requires oxytocics, injection skills, and trained birth attendants.
