Dada RS, Hayanga JWA, Woods A, et al. - Researchers conducted a retrospective study with the aim to evaluate the type of anesthesia administered in atrial fibrillation ablation, hypothesizing that monitored anesthesia care is employed less frequently than general anesthesia. Using National Anesthesia Clinical Outcomes Registry data, which are multi-institutional from across the United States, they appraised a total of 54,321 patients undergoing atrial fibrillation ablation; of these, 3,251 (6.0%) were provided monitored anesthesia care. Observations suggest that atrial fibrillation ablation procedures are conducted primarily under general anesthesia. Variation in anesthetic type was observed with patient, procedural, and hospital characteristics. Thirty-one percent shorter median case duration was recorded for patients receiving monitored anesthesia care.
