Background: Postoperative sore throat is a common and disturbing complication after endotracheal intubation, leading to patient discomfort and dissatisfaction.
Objective: To find out the efficacy of ketamine gargles in reducing the incidence and severity of postoperative sore throat after endotracheal intubation.
Material and method: We studied the role of pre-operative ketamine gargles for reducing postoperative sore throat. Patients undergoing elective abdominal and pelvic surgery under general anaesthesia with endotracheal tube were included in the study. They were randomly allocated in two groups, each group comprising of 30 patients. Group 1(K) received preservative free ketamine 50mg in 29 ml distilled water. Group 2(C) gargled with 30 ml distilled water. Patients were asked to gargle for 30 seconds, 5minutes before induction of anaesthesia. Postoperatively sore throat was assessed at 0, 4, 8 and 24 hours after extubation. The severity of sore throat was assessed from mild to severe.
Results: Immediately after extubation, 90% patients in group C had sore throat compared to 66.7% in group K. 24 hours after extubation, the incidence decreased to 50% in group C and 13.3% in group K. Similar decrease incidence was noted at 4 and 8 hours post extubation in group K. No patient in group K complained of change in voice or hoarseness of voice.
Conclusion: We found that preoperative gargling with ketamine is a simple and cost effective way to reduce the incidence and severity of postoperative sore throat.
