If the amount of bleeding exceeds 500ml within 24 hours after delivery, it means that there is a risk of postpartum hemorrhage, and the doctor will actively deal with it. The amount of postpartum malignant fluid should not exceed the normal amount of menstruation, that is, the amount of the most menstrual day. If the amount of bleeding is more than the amount of menstruation, you need to consider that there may be poor contraction of the uterus, pay attention to the recovery of the uterus, and use appropriate drugs to promote uterine contraction. During hospitalization, you can use uterine contraction, and after returning home, you can take oral medication to promote uterine contraction. At the same time, you should pay attention to rest inside the menstrual period, as poor rest and infection may also lead to increased bleeding.
