The effect of combining lidocaine with dexamethasone for attenuating postoperative sore throat, cough, and hoarseness

摘要

Background: Despite the established efficacy of dexamethasone and lidocaine for preventing postoperative airway symptoms, no study has investigated the effects of dexamethasone plus lidocaine for attenuating postoperative airway symptoms. The purpose of this study was to explore whether combined dexamethasone and lidocaine are superior to dexamethasone alone in reducing postoperative sore throat, cough, and hoarseness for 24 h after tracheal extubation.
