ReviewRefractory uterine atony: still a problem after all these years.
Postpartum hemorrhage is a leading cause of maternal morbidity and mortality, and uterine atony is the leading cause of postpartum hemorrhage. Risk factors for uterine atony include induced or augmented labor, preeclampsia, chorio-amnionitis, obesity, multiple gestation, polyhydramnios, and prolonged second stage of labor. Although a risk assessment is recommended for all parturients, many women with uterine atony do not have risk factors, making uterine atony difficult to predict. ⋯ Rigorous studies are lacking, but methylergonovine and carboprost are likely superior to misoprostol. Currently, the choice of second-line agent should be based on their adverse effect profile and patient comorbidities. Surgical and radiologic management of uterine atony includes uterine tamponade using balloon catheters and compression sutures, and percutaneous transcatheter arterial embolization.

Anesthetic management for the peripartum care of women with Fontan physiology.
As outcomes for surgical palliation have improved, women with single ventricle congenital heart disease are surviving into their reproductive years and may become pregnant. The cardiovascular changes of pregnancy may stress the Fontan circulation and pose significant risk to the mother and fetus. ⋯ Epidural anesthesia is safe and effective for both vaginal and cesarean deliveries. Judicious fluid management is critical in minimizing postpartum cardiovascular complications. Many patients do not require a higher level of care, invasive monitoring or central venous access during the peripartum period.
