Introduction: Post-operative sore throat is one of the most common complications following endotracheal intubation. Though considered minor complication, it may cause significant patient dis-satisfaction. Various non-pharmacological and pharmacological trials have been used with variable results.
Objectives: To compare the efficacy of nebulised dexamethasone with that of nebulised magnesium sulphate in decreasing the incidence and severity of postoperative sore throat (POST).
Materials and Methods: In this prospective double blind study 90 patients undergoing surgery under general anaesthesia with endotracheal intubation lasting <3hr> Results: Compared to group M, significantly lesser number of patients in group D had post-operative sore throat at 0hr (p= 0.0262), 4^th hr (p=0.00022), 8^th hr (p=0.00039) and 12hr (p=0.000657). None of the patients in group D had any hoarseness of voice at 0hr, 4^th hr, 8^th hr of assessment (p= <0> Conclusion: Preoperative dexamethasone nebulisation just before induction of anaesthesia is an effective method of reducing the incidence and severity of POST following endotracheal intubation. Dexamethasone nebulisation reduces the severity of sore throat more effectively than magnesium sulphate nebulisation.
