Postpartum hemorrhage


What does postpartum hemorrhage feel like?
Postpartum hemorrhage refers to the condition where, within 24 hours after vaginal delivery, the amount of blood loss reaches 500 milliliters, and in the case of a cesarean section, the blood loss amounts to 1000 milliliters. During this time, the woman may experience a substantial amount of bleeding from the vagina, along with large blood clots. The primary cause of this condition is often significantly associated with poor contraction of the uterine muscles. Post-delivery, the blood sinuses in the uterine muscle layer are open, requiring the uterus to contract. If the contractions are inadequate, it may lead to bleeding from these blood sinuses. Additionally, bleeding could also potentially stem from post-surgical wounds, such as those from a cesarean section or wounds from vaginal delivery.


Postpartum Hemorrhage Emergency Response Process
Firstly, it is necessary to administer IV fluids to the patient and establish two venous accesses to urgently replenish blood volume. Then, it is important to manage breathing to ensure the patient's airway is clear, and provide oxygen if necessary. Patient's vital signs should also be checked for any abnormalities. Additionally, treatment should be given based on the cause of bleeding. If the bleeding is due to poor uterine contraction, it is crucial to promptly enhance uterine contractions to quickly stop the bleeding. At this time, uterotonic agents can be used, or manual uterine massage can be employed to stem the bleeding. If the bleeding is caused by a surgical incision, then the incision needs to be sutured properly.


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.


Should the uterus be removed due to severe postpartum hemorrhage?
Whether postpartum hemorrhage requires hysterectomy primarily depends on the severity of the hemorrhage and the specific causes of the postpartum hemorrhage. First, if the amount of postpartum hemorrhage is very substantial, leading to conditions like DIC in the pregnant woman, and if not removing the uterus may cause ongoing bleeding, it is essential to remove the uterus quickly to reduce vaginal bleeding. Second, if the postpartum hemorrhage is caused by issues like amniotic fluid embolism or poor contraction of the uterus, and conservative treatments are ineffective, it is also necessary to make a prompt decision to remove the uterus.


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.


Late postpartum hemorrhage clinical symptoms
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.


Postpartum Hemorrhage Prevention Measures
Postpartum hemorrhage can cause significant harm to a woman's body and, in severe cases, can even pose a threat to the patient's life. Therefore, it is crucial to implement preventative measures for postpartum hemorrhage. During prenatal check-ups, it is important to assess whether the pregnant woman has any risks for bleeding, such as checking if her coagulation function is normal. Additionally, it is essential to check for any serious comorbidities, such as hepatitis, renal failure, or other hematological diseases. These conditions should be treated before pregnancy. It is also advised to give birth in a reputable hospital, where the delivery can be conducted under the guidance of experienced doctors in a well-equipped facility. This can help alleviate the tension of the pregnant woman, contributing to a smoother delivery process. Moreover, within the first two hours after childbirth, careful monitoring of vaginal bleeding is necessary. If there is a significant amount of vaginal bleeding, timely hemostatic treatment should be administered.
