Lee Y, et al. - In this retrospective study of children aged > 2 and ≤ 18 years who received general anesthesia for a percutaneous radiofrequency catheter ablation or cryoablation for a tachyarrhythmia between January 1, 2013, and January 1, 2016, researchers investigated the incidence as well as the risk factors for nausea and vomiting in the recovery room. The occurrence of vomiting or retching in the postanesthesia care unit was reported in 7.4% of patients and nausea in an additional 12.4%. The occurrence of a composite of nausea and vomiting was reported in 95 patients (15.5%). A history of PONV was found to be independently related to a composite of nausea and vomiting in the recovery room. A lower rate of postoperative vomiting was predicted by a shorter anesthetic time and a subhypnotic propofol infusion among patients receiving general anesthesia for electrophysiologic ablation procedures.
