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
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
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.
