Strictly speaking, hemorrhage during labor is also included in postpartum hemorrhage, which refers to the hemorrhage caused by the whole process of labor; postpartum hemorrhage refers to the hemorrhage that reaches or exceeds 500 ml for vaginal deliveries and 1,000 ml for cesarean deliveries within 24 hours after the delivery of the fetus. 1. Bleeding during labor: during labor, weak contraction is the main cause of bleeding during labor; soft birth canal injury, cervical, vaginal, vulvar laceration, or cesarean section wound rupture; placenta implantation or retention, which affects the uterine contraction will lead to bleeding; diffuse intravascular coagulation or liver disease will also lead to bleeding. When giving birth, we should find out the cause of the disease in time, and quickly perform uterine massage, uterine balloon placement to stop bleeding, laceration repair, uterine artery embolization, uterine artery ligation, total hysterectomy and so on. 2. Postpartum hemorrhage: Hemorrhage within 24 hours after the delivery of the fetus, the etiology is the same as bleeding during labor, but most of the post-partum hemorrhage is caused by the lack of uterine contraction and retained placenta or fetal appendages, the principle of treatment is to promote uterine contraction, as soon as possible, the residual removal. In full-term pregnancies, if there is a possibility of postpartum hemorrhage during labor, it is necessary to go to a regular hospital to be admitted to the hospital in advance to wait for labor. During and after delivery, under the close observation of professional doctors and nurses, if there is bleeding, excessive bleeding may lead to dizziness or shock symptoms, which need to be quickly stopped or at the same time to establish intravenous access, and for the cause of the active treatment.
