Late postpartum hemorrhage occurs when significant uterine bleeding happens after the first 24 hours following the delivery of the fetus, commonly seen from one to two weeks postpartum. At this time, patients may experience sudden heavy vaginal bleeding, and some may even develop hemorrhagic shock. A minority of patients might not bleed profusely but may experience recurrent bleeding. Additionally, this bleeding is often accompanied by lower abdominal pain, fever, and symptoms of anemia, so it is critical to seek immediate medical treatment upon noticing these symptoms.

The most common cause of postpartum hemorrhage

Postpartum hemorrhage is divided into two scenarios. The first type occurs within 24 hours after childbirth and is seen in four situations. The first is due to inadequate uterine contraction, the second is trauma to the soft birth canal, the third concerns placental factors, and the fourth involves coagulation disorders. The second type of hemorrhage is late postpartum bleeding, which occurs one to two months after childbirth. This can be associated with postpartum infections, slow recovery of physical condition postpartum, retained products, and poor healing of cesarean section scars.

Does postpartum hemorrhage require a blood transfusion?

The definition of postpartum hemorrhage is bleeding greater than 500 milliliters approximately 24 hours after vaginal delivery. Whether blood transfusion is necessary for postpartum hemorrhage mainly depends on the specific amount of bleeding. For average women, if the hemoglobin level is normal before delivery and the bleeding is between 500-1000 milliliters, the body can compensate for the anemia through normal adjustments, and generally, a blood transfusion is not required. However, if the bleeding exceeds 1000 milliliters, this situation is considered massive hemorrhage and must be treated with a blood transfusion, otherwise it may lead to hemorrhagic shock or DIC (Disseminated Intravascular Coagulation).

How long will postpartum bleeding last until it stops?

Generally, in normal childbirth or after cesarean section surgery, there is usually a small amount of vaginal bleeding, which typically subsides completely within about a week. If there is heavy bleeding after delivery, it is crucial to closely monitor the vaginal bleeding to rule out the possibility of delayed postpartum hemorrhage. If the uterus contracts well and there is no retention of placental fragments, the area will generally be clean within about a week, albeit with some bloody discharge. Therefore, if there is abnormal vaginal bleeding postpartum, it is recommended to promptly re-examine to exclude the possibility of late bleeding, so as to avoid endangering life.

Postpartum hemorrhage uterine suturing method

If postpartum hemorrhage occurs, it is foremost important to actively seek the specific causes of the bleeding to achieve timely and rapid hemostasis. It is also necessary to quickly replenish blood volume to prevent shock and infection. Meanwhile, if there is localized bleeding, active local suturing treatment should be pursued to control the bleeding. Normally, if the postpartum bleeding is light, suturing the uterus in the conventional way will suffice. However, if the bleeding is caused by uterine atony or similar reasons and oxytocics are ineffective, procedures like ascending ligation of the uterine arteries or uterine compression sutures and binding can be performed to effectively stop the bleeding.

Causes of Late Postpartum Hemorrhage

Late postpartum hemorrhage is most commonly caused by retained placenta and membranes. About ten days after childbirth, the patient may experience significant bleeding due to the degeneration and necrosis of the retained placental and membrane tissues within the uterine cavity. When these necrotic tissues are shed, it can cause the blood vessels to open and lead to bleeding. Additionally, poor healing of the placental site on the uterus can also cause bleeding, as can infections, with endometritis being relatively common. Inflammation can lead to poor healing of the placental attachment site or poor uterine contraction, resulting in significant uterine bleeding.
