Postpartum hemorrhage generally does not have warning signs but usually has precipitating factors. These factors include maternal fear, psychological tension, macrosomia or twin pregnancy, as well as conditions like uterine fibroids, placental abruption, or placenta previa. In cases of placenta previa during a cesarean section, there is a high likelihood of severe bleeding. There is only one condition that might signal an impending postpartum hemorrhage, which is placental abruption. If placental abruption occurs, it can cause severe abdominal pain along with issues of hypertension during pregnancy. If a person with pregnancy-induced hypertension experiences severe abdominal pain, this could be a precursor to postpartum hemorrhage.

Can postpartum hemorrhage be stopped?

Postpartum hemorrhage primarily refers to bleeding from the vagina exceeding 500 milliliters within 24 hours after the delivery of the fetus, and bleeding exceeding 1000 milliliters for cesarean deliveries. It is classified as postpartum hemorrhage. Normally, active hemostatic symptomatic treatment should be pursued in cases of bleeding after childbirth. The majority of cases are often caused by poor uterine contraction, which significantly raises the likelihood of postpartum hemorrhage. Generally, it is necessary to actively use drugs that promote uterine contractions to help in reducing bleeding by aiding the contraction of the uterus.

Measures for postpartum hemorrhage

Postpartum hemorrhage refers to a situation where there is blood loss exceeding 500 milliliters within 24 hours after the birth of a child. Initially, massaging the uterus should be performed, as most of this bleeding is due to poor uterine contraction, and the doctor can press on the uterus from above the patient's lower abdomen. Additionally, high doses of uterotonic drugs can be used to induce uterine contraction. If these measures do not reduce bleeding, packing the uterine cavity with gauze can be employed to stop the bleeding from the uterus. Furthermore, if the bleeding is very severe, embolization of the uterine artery or the internal iliac artery can be done to halt the uterine bleeding.

The main causes of postpartum hemorrhage

There are four main causes of postpartum hemorrhage: one is uterine atony, two is due to trauma in the soft birth canal, three is due to placental factors, and four is coagulation dysfunction. Uterine atony is the most common cause of postpartum hemorrhage clinically. Various factors can lead to uterine atony, such as maternal exhaustion during labor due to not eating, leading to physical decay, which can also cause uterine atony. Additionally, an excessively large uterus, such as from excessive amniotic fluid, twins, or triplets, can lead to poor uterine contraction and retraction rates after childbirth. As for injuries in the soft birth canal, they mainly occur due to insufficient protection of the perineum during childbirth or inappropriate use of vacuum assistance during the second stage of labor, causing trauma in the soft birth canal. Placental factors include placental adhesion, placenta accreta, partial placental abruption, and retained placenta, all of which can lead to postpartum bleeding due to placental issues.

How much bleeding is considered postpartum hemorrhage?

Postpartum hemorrhage refers to a condition where, if the patient has vaginal delivery, the bleeding exceeds 500 milliliters within 24 hours after the fetus is delivered. If the delivery is via cesarean section, the bleeding exceeds 1000 milliliters, which is considered significant postpartum hemorrhage. The primary cause is mostly related to poor uterine contractions. Due to inadequate muscle contractions of the uterus, the blood vessels in the uterine muscle layer remain open, leading to bleeding. Another cause relates to placental factors, such as when the placenta is not entirely expelled, leading to remnants of the placenta and membranes remaining in the uterine cavity, which can also cause postpartum bleeding.
