Maternal cardiac arrest complicated 8.5 per 100,000 hospitalizations for delivery (99% CI, 7.7-9.3), with 58.9% of affected patients surviving to hospital discharge.

Maternal cardiac arrest during delivery hospitalization is rare (1 in 12,000) but has a survival rate of nearly 60%, with hemorrhage, heart failure, amniotic fluid embolism, and sepsis being the most common etiologies.
BACKGROUND: The objective of this analysis was to evaluate the frequency, distribution of potential etiologies, and survival rates of maternal cardiopulmonary arrest during the hospitalization for delivery in the United States. METHODS: By using data from the Nationwide Inpatient Sample during the years 1998 through 2011, the authors obtained weighted estimates of the number of U.S. hospitalizations for delivery complicated by maternal cardiac arrest. Clinical and demographic risk factors, potential etiologies, and outcomes were identified and compared in women with and without cardiac arrest. The authors tested for temporal trends in the occurrence and survival associated with maternal arrest. RESULTS: Cardiac arrest complicated 1 in 12,000 or 8.5 per 100,000 hospitalizations for delivery (99% CI, 7.7 to 9.3 per 100,000). The most common potential etiologies of arrest included hemorrhage, heart failure, amniotic fluid embolism, and sepsis. Among patients with cardiac arrest, 58.9% of patients (99% CI, 54.8 to 63.0%) survived to hospital discharge. CONCLUSIONS: Approximately 1 in 12,000 hospitalizations for delivery is complicated by cardiac arrest, most frequently due to hemorrhage, heart failure, amniotic fluid embolism, or sepsis. Survival depends on the underlying etiology of arrest.
Mhyre et al. (Wed,) conducted a observational in Hospitalization for delivery. Maternal cardiac arrest vs. Women without cardiac arrest was evaluated on Frequency of maternal cardiac arrest during hospitalization for delivery (per 100,000) (95% CI 7.7 to 9.3). Maternal cardiac arrest complicated 8.5 per 100,000 hospitalizations for delivery (99% CI, 7.7-9.3), with 58.9% of affected patients surviving to hospital discharge.
