What are the 4 most common causes of postpartum hemorrhage?

The Four T’s mnemonic can be used to identify and address the four most common causes of postpartum hemorrhage (uterine atony [Tone]; laceration, hematoma, inversion, rupture [Trauma]; retained tissue or invasive placenta [Tissue]; and coagulopathy [Thrombin]).

When does uterine atony happen?

Uterine atony is the most common cause of PPH, accounting for 70% to 80% of cases. This occurs when there is decreased contraction of the myometrium. The postgravid uterus is floppy or flaccid and unable to provide adequate compression for hemostasis.

How oxytocin causes uterine atony?

Therefore, prolonged oxytocin treatment leads to OXTR desensitization, thereby limiting further oxytocin-mediated contraction responses. We propose that prolonged oxytocin treatment leads to OXTR desensitization that interferes with uterine contractility, leading to uterine atony and PPH.

How common is uterine atony?

Uterine atony occurs during 1 in 40 births in the United States and is responsible for at least 80% of cases of postpartum hemorrhage.

How do you know if you are hemorrhaging?

Signs of internal hemorrhaging include: abdominal pain. blood in the stool. blood in the urine….Signs of Hemorrhagic Shock

  1. anxiety.
  2. blue lips and fingernails.
  3. low or no urine output.
  4. profuse (excessive) sweating.
  5. shallow breathing.
  6. dizziness.
  7. confusion.
  8. chest pain.

What is the treatment for uterine atony?

Uterine atony is responsible for most cases and can be managed with uterine massage in conjunction with oxytocin, prostaglandins, and ergot alkaloids. Retained placenta is a less common cause and requires examination of the placenta, exploration of the uterine cavity, and manual removal of retained tissue.

What causes PPH?

Uterine atony. This is the most common cause of PPH. It happens when the muscles in your uterus don’t contract (tighten) well after birth. Uterine contractions after birth help stop bleeding from the place in the uterus where the placenta breaks away.

What is the risk factor for uterine atony?

Risk factors for uterine atony include uterine overdistention secondary to hydramnios, multiple gestation, use of oxytocin, fetal macrosomia, high parity, rapid or prolonged labor, intra-amniotic infection and use of uterine-relaxing agents.

What does it mean to have uterine atony?

Uterine atony means the loss of tone in the uterine musculature. During labor, the uterine muscles contract, compressing the blood vessels and reducing the blood flow. This, in turn, increases the likelihood of coagulation and prevents hemorrhage.

How to prevent atony of the uterus after delivery?

Preventing Atony of the Uterus. Uterine massage right after delivery of the placenta may also reduce the risk of atony of the uterus and is now a common practice. Taking prenatal vitamins, including iron supplements, can also help prevent anemia and other complications of uterine atony and hemorrhage after delivery.

Can a uterine atony cause postpartum bleeding?

Atony of the uterus is the primary cause of postpartum hemorrhage. Postpartum hemorrhage is excessive bleeding post-delivery and occurs after the placenta is delivered.

How does hard labor cause uterine atony?

Hard labor may increase the risk of a woman developing uterine atony. A woman’s uterine muscles usually contract to stop bleeding after the baby and the placenta are delivered. The muscles work to constrict exposed blood vessels, stopping the flow of blood and repairing uterine walls.

What is the primary cause of postpartum hemorrhage?

The major causes of primary postpartum hemorrhage include uterine atony, retained placenta, lower genital tract lacerations and hematomas, uterine rupture, consumptive coagulopathy, and acute inversion of the uterus.

What are the most important risk factors for postpartum hemorrhage?

Risk factors for postpartum hemorrhage among the deliveries were: fetal macrosomia (over 4000 g); pregnancy-induced hypertension; pregnancy generated by assisted reproductive technology; severe vaginal or perineal lacerations; and weight gain over 15 kg during pregnancy.

How do I know if I’m hemorrhaging after birth?

These are the most common symptoms of postpartum hemorrhage: Uncontrolled bleeding. Decreased blood pressure. Increased heart rate.

How do you know if your hemorrhaging?

Signs of very severe hemorrhaging include: very low blood pressure. rapid heart rate. sweaty, wet skin that often feels cool to the touch.

How much blood loss is considered a hemorrhage?

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 (or about a half of a quart). The average amount of blood loss for a cesarean birth is approximately 1,000 ml (or one quart).

How common is late postpartum hemorrhage?

Incidence and Associated Conditions. The incidence of secondary hemorrhage is up to 2% of all postpartum women; leading causes are placental retention, subinvolution of the placental bed, and endometritis.

How do you stop hemorrhaging after giving birth?

Treatment for postpartum hemorrhage may include:

  1. Medication (to stimulate uterine contractions)
  2. Manual massage of the uterus (to stimulate contractions)
  3. Removal of placental pieces that remain in the uterus.
  4. Examination of the uterus and other pelvic tissues.

What are the causes of postpartum hemorrhage in women?

Other causes of postpartum hemorrhage include. Lacerations of the genital tract. Extension of an episiotomy. Uterine rupture. Bleeding disorders. Retained placental tissues. Hematoma. Uterine inversion.

What causes bleeding in uterus after postpartum?

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.

Can a placenta tear cause a postpartum hemorrhage?

If small pieces of the placenta stay attached, bleeding is also likely. Postpartum hemorrhage may also be caused by: Tear in the cervix or tissues of the vagina. Tear in a blood vessel in the uterus. Bleeding into a hidden tissue area or space in the pelvis.

What to do if you have postpartum hemorrhage?

The major causes of postpartum hemorrhage are uterine atony, lacerations, retained placenta or clots, and clotting factor deficiency. Uterine massage, oxytocin, and methylergonovine are the main treatments, along with blood transfusion and cardiovascular support.

What are the risk factors for postpartum hemorrhage?

Labour induction, augmentation of labour, and prior Caesarean section are significantly associated with the risk of PPH, and their increase over the study period largely explains the observed rise in PPH.
