What is the cause of prolonged postpartum bleeding?

Long-term postpartum bleeding must be taken seriously. Even a small amount of bleeding, if not taken seriously, can easily cause infection or lead to hemorrhagic anemia. The reasons leading to postpartum initiation are complex. For example, factors such as uterine atony or placental infection can cause bleeding. In addition, postpartum birth canal injury and coagulation dysfunction are also causes of bleeding. The patient must go to the hospital for a detailed examination to determine the cause of the bleeding.

Uterine inversion can lead to postpartum hemorrhage, which is rare and is mostly caused by improper management of the third stage of labor, such as forceful compression of the uterine fundus or violent traction on the umbilical cord.

Coagulation dysfunction can lead to postpartum hemorrhage. Common causes include coagulation dysfunction caused by placental abruption, amniotic fluid embolism, stillbirth and acute fatty liver of pregnancy. A few cases are caused by primary blood diseases such as thrombocytopenia, leukemia, aplastic anemia or severe viral hepatitis.

Soft birth canal lacerations can lead to postpartum hemorrhage. Soft birth canal lacerations include lacerations of the perineum, vagina, cervix, and lower uterine segment. Common factors: poor elasticity of vulvar tissue, inflammatory changes of the vulva and vagina; premature delivery, excessive labor force, macrosomia; vaginal surgery to assist delivery; careless examination of the soft birth canal, missing bleeding spots. Incomplete suture and hemostasis, etc.

Placental factors can lead to postpartum hemorrhage and retained placenta: if the placenta has not been expelled within 30 minutes after the fetus is delivered, it is called retained placenta. It may be due to improper use of uterotonic agents or rough massage of the uterus, which stimulates spasmodic contractions and forms a contraction ring at the junction of the upper and lower segments of the uterus or at the external os of the cervix.

After understanding the general causes of postpartum hemorrhage, if you experience postpartum hemorrhage, you must go to the hospital for examination in time to find out the cause before treatment. Actively strengthen prenatal examinations and take active measures to prevent high-risk factors that may lead to postpartum hemorrhage, which can effectively avoid postpartum hemorrhage. Delivery must be carried out in a regular hospital. In addition, during delivery, midwives and nurses must be gentle and not rough.
