Follicular Tonsillitis (Chronic)
Conditions
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.
Interventions
DRUGfentanyl at 10-15 min before end of surgery
Label 2 syringe is filled with 1mcg/kg of fentanyl, label 1 syringe is filled with same amount of saline solution. If the surgeon notifies the anesthesiologist 10-15 minutes before the end of the operation, the syringe drug labeled 1 will be administered intravenously(that is, normal saline ). At the end of the surgery, the syringe drug labeled 2 is administered intravenously((that is, 1mcg/kg of fentanyl)
DRUGfentanyl at end of surgery
Label 2 syringe is filled with 1mcg/kg of fentanyl, label 1 syringe is filled with same amount of saline solution. If the surgeon notifies the anesthesiologist 10-15 minutes before the end of the operation, the syringe drug labeled 1 will be administered intravenously(that is, normal saline ). At the end of the surgery, the syringe drug labeled 2 is administered intravenously((that is, 1mcg/kg of fentanyl)

| Incidence of postoperative nausea and vomiting | 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
| Measure | Time frame | Description |
|---|---|---|
| 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 | \*Pediatric Anesthesia Emergence Delirium scale: range 0-20 points. If the score is more than 12, it is considered to be EA occurrence. |
| 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 | \*five-step Emergence Agitation scale: range 1-5 score.
