Comparison between intravenous lidocaine and dexamethasone in reducing postoperative sore throat after endotracheal extubation at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia; a prospective cohort study

Abstract

The incidence of POST was 40%, 32%, and 57.1% in the lidocaine, dexamethasone, and control groups, respectively (P = .0356). Dexamethasone reduced the incidence of POST during the first 24 h (AOR: 0.374, 95% CI: 0.149-0.939). However, no difference was observed in the severity of POST at 3 h (p = 0.130), 6 h (p = 0.096), 12 h (p = 0.313), and 24 h (p = 0.525) of the post-extubation period among the three groups. IV lidocaine did not effectively reduce the incidence and severity of postoperative sore throat at different time intervals. CONCLUSION AND RECOMMENDATION: Intravenous dexamethasone is more effective than intravenous lidocaine in reducing the incidence of postoperative sore throat among the groups. Based on these findings, intravenous dexamethasone is recommended to decrease the incidence of postoperative sore throat.
