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]).
What are the 3 main causes of postpartum hemorrhage?
Causes. Causes of postpartum hemorrhage are uterine atony, trauma, retained placenta or placental abnormalities, and coagulopathy, commonly referred to as the “four Ts”: Tone: uterine atony is the inability of the uterus to contract and may lead to continuous bleeding.
What are the 4 T’s of PPH?
Remember the 4 Ts: tone, trauma, tissue, and thrombin.
What causes uterine Atony?
The most common cause of PPH is uterine atony. Patients at increased risk for uterine atony include those with high parity, overdistended uterus (e.g., multiple gestation, polyhydramnios), prolonged or rapid labor, use of oxytocin for induction or augmentation, and use of magnesium sulfate.
Who is at risk for postpartum hemorrhage?
Some women are at greater risk for postpartum hemorrhage than others. Conditions that may increase the risk include: Placental abruption. This is the early detachment of the placenta from the uterus.
Who is most at risk for postpartum hemorrhage?
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.
- Overdistended uterus.
- Multiple pregnancy.
- Gestational hypertension or preeclampsia.
- Having many previous births.
- Prolonged labor.
Can you die from postpartum hemorrhage?
Postpartum hemorrhage is heavy bleeding after the birth of your baby. Losing lots of blood quickly can cause a severe drop in your blood pressure. It may lead to shock and death if not treated.

What are the types of PPH?
PPH can be divided into 2 types: early (< 24 hours after delivery) and late (24 hours to 6 weeks after delivery). Most cases of PPH (>99%) are early.
How can you prevent PPH?
Oxytocin is more effective than misoprostol for prevention and treatment of uterine atony and has fewer adverse effects. Routine episiotomy should be avoided to decrease blood loss and the risk of anal laceration. Appropriate management of postpartum hemorrhage requires prompt diagnosis and treatment.
How do you fix uterine Atony?
Treatment. The first step in management of uterine atony is uterine massage. The next step is pharmacological therapies, the first of which is oxytocin, used because it initiates rhythmic contractions of the uterus, compressing the spiral arteries which should reduce bleeding.
What is the treatment for uterine Atony?
Treatment for Atony of the Uterus
uterine massage, which involves your doctor placing one hand in the vagina and pushing against the uterus while their other hand compresses the uterus through the abdominal wall. uterotonic drugs including oxytocin, methylergonovine (Methergine), and prostaglandins, such as Hemabate.
How can you prevent uterine rupture?

- plan to become pregnant before the age of 30.
- not opt to have a C-section unless it’s absolutely necessary.
- avoid having an additional pregnancy within 2 years of a C-section.
- keep all doctor’s appointments, especially in the last trimester of pregnancy.

It’s a serious but rare condition. It usually happens within 1 day of giving birth, but it can happen up to 12 weeks after having a baby. About 1 to 5 in 100 women who have a baby (1 to 5 percent) have PPH.
How much blood loss is considered a hemorrhage?
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). Most postpartum hemorrhage occurs right after delivery, but it can occur later as well.
Can postpartum bleeding start and stop?
After you give birth your body makes use of the vaginal bleeding to get rid of the lochia from the uterus. In the first few days after delivery, the bleeding may be heavy. But it will gradually subside as the days go by and by the 6th week of your postpartum, it stops.
