Among them, postpartum hemorrhage can be classified into early postpartum hemorrhage and late postpartum hemorrhage according to bleeding time. Postpartum hemorrhage refers to the condition that within 24 hours after delivery of the fetus, the amount of bleeding of a vaginal delivery person is more than or equal to 500mL, and the cesarean section is more than or equal to 1000 mL. Early postpartum hemorrhage mostly occurs within 2 hours of postpartum. And late postpartum hemorrhage refers to massive uterine bleeding occurring in puerperium 24 hours after parturition. Late postpartum hemorrhage is usually seen in 1-2 weeks postpartum. Postpartum hemorrhage is a public health problem in the world and is the leading cause of morbidity and mortality of pregnant and lying-in women, and according to reports of relevant documents at home and abroad, the morbidity of the postpartum hemorrhage is 5% -10%, but the actual morbidity of the postpartum hemorrhage is higher because the clinically estimated postpartum hemorrhage amount is often lower than the actual hemorrhage amount.

Uterine contraction and weakness are the most common reasons for postpartum hemorrhage, and active hemostatic treatment is the key to avoid unnecessary hysterectomy and reduce the death of pregnant and lying-in women. The uterine contraction can be strengthened to stop bleeding quickly, and the conventional methods comprise massage or pressing uterus and using a uterine contraction inhibitor. If the above method is ineffective, uterine cavity filling should be considered as early as possible to achieve better hemostatic effect.
