Overview
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.

Outcomes
Primary Outcomes
Incidence of postoperative nausea and vomiting
Time Frame: In 10-minute increments from immediately(less than 3 min) after entering PACU to departure
Occurrence of nausea and vomiting- Described as yes/no (Observation of medical personnel or Subjective symptoms of the patient by the definition below) Nausea: "feeling of the urge to vomit" vomiting: "retching and any expulsion of liquid gastric contents"
Secondary Outcomes
- FLACC score FLACC score (Face, Legs, Activity, Cry, Consolability scale): range 0-10. If the score is 4 or more, Pain control is considered necessary.(In 10-minute increments from immediately after entering PACU to departure)
- PAED scale score: *Pediatric Anesthesia Emergence Delirium scale: range 0-20 points. If the score is more than 12, it is considered to be EA occurrence.(In 10-minute increments from immediately(less than 3 min) after entering PACU to departure)
- five-step EA scale: *five-step Emergence Agitation scale: range 1-5 score. If the score is 4 or more, it is regarded as EA occurrence.(In 10-minute increments from immediately(less than 3 min) after entering PACU to departure)
- anesthesia recovery time(up to 1 day after end of surgery)
- Occurrence of side effect(In 10-minute increments from immediately(less than 3 min) after entering PACU to departure)
