Resuscitative hysterotomy is an emergency cesarean section operation performed during maternal cardiac arrest in order to increase chances of survival of the mother, the infant, or both.
It is indicated in the second half of pregnancy, when the uterine fundus is above the level of the umbilicus.
Decompressing the uterus can improved maternal ventilation and circulation during CPR and improve the chances of return of spontaneous circulation.
