Effect of Intravenous Fentanyl on the Occurrence of Postoperative Nausea and Vomiting According to Time of Administration Around the End of Tonsillectomy With or Without Adenoidectomy

Not Applicable

Completed

• Conditions: Follicular Tonsillitis (Chronic)
• Interventions: Drug: fentanyl at end of surgery; Drug: fentanyl at 10-15 min before end of surgery

• Registration Number: NCT03343002
• Lead Sponsor: Yonsei University

Brief Summary

Fentanyl is a commonly used drug for the prevention of emergence agitation and reduction in postoperative pain in children receiving tonsillectomy. However, fentanyl can cause postoperative nausea and vomiting (PONV), which is a main target side effect that medical staff strives to prevent. However, recent meta-analysis showed that the incidence of PONV may be different depending on the time of administration of fentanyl. However, the research design of patients enrolled in each study, such as the age, the name of the operation, and the method of anesthesia, is not identical. The aim of this study was to evaluate the efficacy and safety of fentanyl in patients undergoing tonsillectomy with a prospective randomized controlled trial. Secondary outcomes include incidence and severity of emergence agitation and anesthesia recovery time, postanesthesia care unit (PACU) time, side effects.
