Abstract

Background: Postoperative sore throat (POST) is an undesirable complaint from patients undergoing general anesthesia. Dexamethasone, with its potent immunomodulatory effects, is used to reduce inflammation and tissue damage in a variety of clinical settings. The present study aimed to evaluate the effect of dexamethasone on the incidence of POST systematically. 

Methods: Two researchers searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Google scholar, World Health Organization International Clinical Trials Registry Platform, Chinese BioMedical Literature Database, and China National Knowledge Infrastructure for randomized controlled trials that compared dexamethasone in patients undergoing general anesthesia and reported the outcome of POST. 

Results: Five studies with a total of 582 patients receiving dexamethasone or placebo were included. The pooled results revealed that patients receiving dexamethasone had a lower incidence of POST at 1 hour (relative risk [RR]=0.63, 95% confidence interval [CI] 0.40-0.98, P<0.05) and 24 hours (RR=0.42, 95% CI 0.30-0.60, P<0.001) after surgery. 

Conclusions: Prophylactic dexamethasone is effective in decreasing the incidence of POST after surgery relative to placebo.
