In general, it takes 5-15 minutes, not more than 30 minutes, after the delivery of the fetus to deliver the placenta. If this time is too long, the placenta can be manipulated to help it to be delivered. Usually, after the delivery of the fetus, the volume of the uterine cavity is significantly reduced, and the placenta can be dislocated from the uterine wall. As the uterus continues to contract, the placenta can be completely detached and expelled from the vagina. This process takes about 5-15 minutes and no more than 30 minutes. If the placenta has not been expelled for a long time and retention of the placenta is suspected, a uterine examination should be performed. If the placenta is already detached, it can be removed by peeling the placenta with bare hands. If it is difficult to detach the placenta, local excision or hysterectomy should be performed according to the patient’s condition. If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
