User:Mr. Ibrahem/Uterine atony

Uterine atony is the failure of the uterus to contract adequately following delivery. Symptoms can include post partum bleeding, of which it is the causes in more than 75% of cases. Complications may include anemia and iron deficiency.

Risk factors include prolonged labor, precipitous labor, uterine distension (twins, polyhydramnios, large for gestational age), fibroids, BMI > 40, and chorioamnionitis. Contraction of the muscles of the uterus is required to close the blood vessels that supply were the placenta attaches after its delivery. Diagnosis is by feeling the uterus following delivery. Other conditions that may present similarly include retained placenta, uterine inversion, and lacerations associated with delivery.

Blood products should be ready for us in those at high risk. Oxytocin may also be given to try to prevent its occurrence. Treatment may include uterine massage, medications, uterus packing, or surgery. Medications used include oxytocin, methylergometrine, carboprost, misoprostol, and prostaglandin E2. Uterine atony occurs in 2.5% of deliveries in the United States. Globally postpartum bleeding is a top 5 causes of maternal death.
