ObjectiveTo assess the impact of intraoperative intravenous dexamethasone on the reduction of postoperative morbidity in children undergoing adenotonsillectomy.MethodsA double blind randomized controlled trial conducted among children undergoing adenotonsillectomy at a tertiary hospital in Korea from November 2018 to June 2019. Children were randomly assigned to receive dexamethasone (0.5 mg/kg, maximum dose 24 mg) or placebo intravenously after induction of anesthesia. The primary endpoint was the reduction of postoperative pain and postoperative nausea and vomiting (PONV); secondary endpoints were adverse effects like postoperative hemorrhage.ResultsThe study included 105 children, and 67 were male. Their mean age was 6.2 ± 2.1 years. There was no significant difference between the groups in terms of demographic data or the operation time. The pain scores of the dexamethasone group were lower than those of the control group, but no significant difference was found (all P > .05). The average pain visual analog scale (VAS) during the study period (day 0-7) was 3.67 ± 1.59 and 4.40 ± 2.01 in the dexamethasone group and control group, respectively (P-value = .107). When we compared early pain VAS (day 0-2) and late pain VAS (day 5-7), the dexamethasone group showed significantly lower early mean VAS compared to the control group (4.55 ± 1.78 vs 5.40 ± 2.05, P-value = .046). The mean VAS for PONV was significantly lower in the dexamethasone group than in the control group (1.89 ± 2.22 vs 3.00 ± 2.37, P value = .044).ConclusionIn children undergoing adenotonsillectomy, dexamethasone decreased the early postoperative pain and PONV without increasing postoperative hemorrhage.Copyright © 2021 the Author(s).
