| Background and Aims Postoperative sore throat (POST) is common after endotracheal intubation making patients uncomfortable and anxious in postoperative period. The present study was undertaken to compare efficacy of equal dose of dexamethasone in preventing POST via three different routes, i.e., intravenous, topical, and nebulization before surgery. Methods and Results The present prospective double-blind randomized parallel group trial included 190 patients of either sex above 18 years, American Society of Anesthesiologists (ASA) physical status I–II posted for laparoscopic cholecystectomy. The patients were divided into three groups. Patients in group N were nebulized with 8 mg dexamethasone prior to surgery, patients in group I received intravenous dexamethasone (8 mg) before induction of anesthesia, while patients in group C were intubated with endotracheal tube which was pretreated (cuff soaked in dexamethasone 8 mg). The severity of POST and hoarseness of voice was determined by interviewing patients after 24-h of completion of surgery. Incidence of POST decreased in all patients with maximum decrease in group N (18%), while 30.8% in group I and 30.4% in group C. This decrease was not statistically significant when compared to group I ( 0.14) as well as group C ( 0.15). Incidence of hoarseness significantly decreased in group N (15.6%) as compared to group I (40.3%) as well as group C (39.1%). This decrease was statistically significant when compared to group I ( 0.005) as well as group C ( 0.009). Conclusions Topical dexamethasone (group C) is as effective as intravenous dexamethasone in decreasing incidence of POST, while both the techniques are not effective in decreasing hoarseness of voice. Nebulization is most effective method in decreasing POST as well as hoarseness. Trial Registration dated 29 August 2017 prospectively. | ||
