Normally, the best time for postpartum evacuation is about 1 week after delivery. However, if the presence of residual tissue in the uterine cavity causes heavy vaginal bleeding, the uterus should be cleared immediately. When there is fetal membrane or placental tissue remaining in the uterine cavity after delivery, the uterus should be cleared. If the patient’s general condition is good, it is recommended that the uterus be cleared about 1 week after delivery, when the uterine contraction is relatively good, which can reduce vaginal bleeding and the chance of uterine perforation. However, if any tissue is found to remain in the uterus after delivery and is accompanied by heavy vaginal bleeding, then it is recommended that the uterus be cleared in time to avoid postpartum hemorrhage. After postpartum hysterectomy, the removed tissues should be sent for pathologic examination to rule out intrauterine infection. In addition, antibiotics should be given promptly after the procedure, and attention should be paid to keeping the vulva clean and dry to avoid secondary infection.
