Postoperative nausea and vomiting in children and adolescents undergoing radiofrequency catheter ablation: a randomized comparison of propofol- and isoflurane-based anesthetics.

UNLABELLED: In children, radiofrequency catheter ablation (RFCA) is typically performed under general anesthesia. With the use of volatile anesthetics, postoperative nausea and vomiting (PONV) are common, with an incidence of emesis as frequent as 60%. We tested the hypothesis that a propofol (PRO)-based anesthetic would have a less frequent incidence of PONV than an isoflurane (ISO)-based anesthetic. Patients were randomly assigned to receive either an ISO- or PRO-based anesthetic. Prophylactic ondansetron was given to all patients and droperidol was used as a rescue antiemetic postoperatively while PONV was monitored postoperatively for 18 h. The incidence of nausea, vomiting, use of rescue antiemetic drugs, and sedation scores were recorded. The cost for the anesthetic was also calculated. Fifty-six subjects were included in this study. The cumulative incidence of PONV was significantly more frequent in group ISO (63% nausea/55% emesis) compared with group PRO (21% nausea/6% emesis). After the administration of droperidol, further vomiting occurred in 70% of the patients in group ISO versus 0% of the patients in group PRO. We conclude that RFCA using ISO has a high PONV risk and the prophylactic use of ondansetron as well as antiemetic therapy with droperidol are ineffective. In contrast, a PRO-based anesthetic is highly effective in preventing PONV in children undergoing RFCA. IMPLICATIONS: In children undergoing radiofrequency catheter ablation and receiving prophylactic ondansetron, a frequent incidence (60%) of postoperative vomiting was observed under an isoflurane-based anesthetic, whereas the incidence was significantly reduced to a very low level (5%) under a propofol-based anesthetic.
