Following a prolonged induction of labor for severe preeclampsia, a patient at weeks gestation experiences a spontaneous vaginal delivery of a g infant. She is years old and this is her first pregnancy. Ten minutes after the placenta is delivered, she develops brisk, steady vaginal hemorrhage. Her blood pressure is mm Hg, and her pulse is /min. On physical examination, the uterine fundus is soft, boggy, and palpated at the level of the umbilicus. A continuous intravenous oxytocin infusion and bimanual uterine massage are immediately initiated, but the excessive bleeding persists. Two large-bore intravenous lines are secured, and aggressive fluid resuscitation is underway.
Arrange the following interventions in the most appropriate sequential order for the continued management of this patient's hemorrhage, proceeding from the most immediate next step to the final definitive measure.
- 1Administer intramuscular carboprost tromethamine
- 2Insert an intrauterine balloon tamponade
- 3Perform a laparotomy with placement of uterine compression sutures
- 4Perform a peripartum hysterectomy
