One in 12,000 Hospital Deliveries Result in Cardiac Arrest

Hemorrhage, heart failure, amniotic fluid embolism or sepsis most frequent causes of arrest

FRIDAY, March 28, 2014 (HealthDay News) -- Cardiac arrest occurs in approximately one of every 12,000 hospitalizations for delivery, according to a study published in the April issue of Anesthesiology.

Jill M. Mhyre, M.D., from the University of Michigan in Ann Arbor, and colleagues calculated weighted estimates of the number of U.S. hospitalizations for delivery complicated by maternal cardiac arrest using data from the Nationwide Inpatient Sample (1998 through 2011). They also compared clinical and demographic risk factors, potential etiologies, and outcomes for women with and without cardiac arrest.

The researchers found that one in 12,000 hospitalizations for delivery (8.5 per 100,000) were complicated by cardiac arrest. Hemorrhage, heart failure, amniotic fluid embolism, and sepsis were the most common potential etiologies of arrest. More than half of patients with cardiac arrest (58.9 percent) survived to hospital discharge, with survival dependent on the underlying etiology of arrest.

"The epidemiology of maternal cardiac arrest described in this report may be used to guide the further development of training courses and systems preparations to manage these life-threatening emergencies," the authors write.
