BACKGROUND: Dexamethasone has been shown to cause inhibition of sugammadex reversal in functionally innervated human muscle cells. In this prospective, double-blind, randomized, controlled study, we evaluated the effect of dexamethasone on the reversal time of sugammadex in children undergoing tonsillectomy and/or adenoidectomy.

METHODS: We recruited 60 patients with ASA physical status I to II, between the ages of 3 and 8 years, scheduled for elective tonsillectomy and/or adenoidectomy. After the induction of anesthesia, patients in group D received IV dexamethasone at a dose of 0.5 mg/kg within a total volume of 5 mL saline, whereas patients in group S received only 5 mL IV saline as the control group. At the end of surgery, all patients were given a single bolus dose (2 mg/kg) of sugammadex at reappearance of T2. Demographic data, hemodynamic variables, time to recovery (a train-of-four ratio of 0.9), time to tracheal extubation, and adverse effects were recorded.

RESULTS: There was no statistical significance between 2 groups in time to recovery and time to extubation. Time to recovery was 97.7 ± 23.9 seconds in group D and 91.1 ± 39.5 seconds in group S (P = 0.436; 95% confidence interval, −10.3 to 23.5). Time to extubation was 127.9 ± 23.2 seconds and 123.8 ± 38.7 seconds in group D and in group S, respectively (P = 0.612; 95% confidence interval, −11.9 to 20.05).

CONCLUSIONS: IV dexamethasone, given after induction of anesthesia, at a dose of 0.5 mg/kg, does not substantively affect the reversal time of sugammadex in pediatric patients undergoing adenoidectomy and/or tonsillectomy.
