Postpartum hemorrhage in Kenya

postpartum hemorrhage

Postpartum hemorrhage is a serious condition that causes excessive blood loss. It can be fatal. It occurs after child birth or before 12 weeks after delivery.

There are different causes, risks, and treatment procedures for postpartum hemorrhage. Blood of about 500 ml is lost during vaginal delivery. Discover more about the complication.

What is postpartum hemorrhage?

Postpartum hemorrhage is excessive bleeding following the birth of a baby. About 4 percent of women have postpartum hemorrhage and it is more likely with a cesarean birth. Hemorrhage may occur before or after the placenta is delivered. The average amount of blood loss after the birth of a single baby in vaginal delivery is about 500 ml. The average amount of blood loss for a cesarean birth is approximately 1,000ml. Most postpartum hemorrhage occurs right after delivery, but it can occur later as well.

What causes postpartum hemorrhage?

Once a baby is delivered, the uterus normally continues to contract (tightening of uterine muscles) and expels the placenta. After the placenta is delivered, these contractions help compress the bleeding vessels in the area where the placenta was attached. If the uterus does not contract strongly enough, called uterine atony, these blood vessels bleed freely and hemorrhage occurs. This is the most common cause of postpartum hemorrhage. If small pieces of the placenta remain attached, bleeding is also likely. It is estimated that as much as 600 ml of blood flows through the placenta each minute in a full-term pregnancy. 

Some women are at greater risk for postpartum hemorrhage than others. Conditions that may increase the risk for postpartum hemorrhage include the following:

– Placental abruption – the early detachment of the placenta from the uterus.

– Placenta previa – the placenta covers or is near the cervical opening.

– Overdistended uterus – excessive enlargement of the uterus due to too much amniotic fluid or a large baby, especially with birthweight over 4,000 grams.

– Multiple pregnancy – more than one placenta and overdistention of the uterus.

– Pregnancy-induced hypertension (PIH) – high blood pressure of pregnancy.

– Having many previous births.

– Prolonged labor.

– Infection.

– Obesity.

– Medications to induce labor.

– Medications to stop contractions (for preterm labor).

– Use of forceps or vacuum-assisted delivery.

– General anesthesia.

Postpartum hemorrhage may also be due to other factors including the following:

– Tear in the cervix or vaginal tissues.

– Tear in a uterine blood vessel.

– Bleeding into a concealed tissue area or space in the pelvis which develops into a hematoma, usually in the vulva or vaginal area.

– Blood clotting disorders such as disseminated intravascular coagulation.

– Placenta accreta – the placenta is abnormally attached to the inside of the uterus (a condition that occurs in one in 2,500 births and is more common if the placenta is attached over a prior cesarean scar).

– Placenta increta – the placental tissues invade the muscle of the uterus.

– Placenta percreta – the placental tissues go all the way into the uterine muscle and may break through (rupture).

Although an uncommon event (one in 2,000 deliveries), uterine rupture can be life threatening for the mother. Conditions that may increase the risk of uterine rupture include surgery to remove fibroid (benign) tumors and a prior cesarean scar in the upper part (fundus) of the uterus. It can also occur before delivery and place the fetus at risk as well.

Why is postpartum hemorrhage a concern?

Excessive and rapid blood loss can cause a severe drop in the mother’s blood pressure and may lead to shock and death if not treated.

What are the symptoms of postpartum hemorrhage?

The following are the most common symptoms of postpartum hemorrhage. However, each woman may experience symptoms differently. Symptoms may include: 

– Uncontrolled bleeding.

– Decreased blood pressure.

– Increased heart rate.

– Decrease in the red blood cell count (hematocrit).

– Swelling and pain in tissues in the vaginal and perineal area.

The symptoms of postpartum hemorrhage may resemble other conditions or medical problems. Always consult your physician for a diagnosis.

How is postpartum hemorrhage diagnosed?

In addition to a complete medical history and physical examination, diagnosis is usually based on symptoms, with laboratory tests often helping with the diagnosis. Tests used to diagnose postpartum hemorrhage may include:

– Estimation of blood loss (this may be done by counting the number of saturated pads, or by weighing of packs and sponges used to absorb blood; 1 milliliter of blood weighs approximately one gram).

– Pulse rate and blood pressure measurement.

– Hematocrit (red blood cell count).

– Clotting factors in the blood.

Treatment for postpartum hemorrhage

Specific treatment for postpartum hemorrhage will be determined by your physician based on:

– Your pregnancy, overall health and medical history.

– Extent of the condition.

– Your tolerance for specific medications, procedures or therapies.

– Expectations for the course of the condition.

– Your opinion or preference.

The aim of treatment of postpartum hemorrhage is to find and stop the cause of the bleeding as quickly as possible. Treatment for postpartum hemorrhage may include:

– Medication (to stimulate uterine contractions).

– Manual massage of the uterus (to stimulate contractions).

– Removal of placental pieces that remain in the uterus.

– Examination of the uterus and other pelvic tissues.

– Packing the uterus with sponges and sterile materials (to compress the bleeding area in the uterus).

– Tying-off of bleeding blood vessels.

– Laparotomy – surgery to open the abdomen to find the cause of the bleeding.

– Hysterectomy – surgical removal of the uterus; in most cases, this is a last resort.

Replacing lost blood and fluids is important in treating postpartum hemorrhage. Intravenous (IV) fluids, blood, and blood products may be given rapidly to prevent shock. The mother may also receive oxygen by mask. 
Postpartum hemorrhage can be quite serious. However, quickly detecting and treating the cause of bleeding can often lead to a full recovery. Contact our gynaecologists for help today. Our women clinic is ready to help you recover in the journey.
