Abstract:
BACKGROUND: Postintubational sore throat and hoarseness are usually mild symptoms but they are very common complaints among the patients after endotracheal general anesthesia. In addition, some might have severe discomfort and need invasive procedure to relieve these problems. We tried new method of endotracheal tube cuff filling with local anesthetics to reduce postoperative sore throat and hoarseness and evaluated the results. METHODS: Endotracheal cuff filling was done with air 5 ml in healthy 20 patients (ASA I-II, control group). And in another healthy (ASA I-II) 35 patients, the cuffs were filled with 4% lidocaine 3.5 ml and 8.4% sodium bicarbonate 1.5 ml mixture. After 24 hours following general anesthesia, patients were visited and asked whether there were sore throat or hoarseness, if any, how the degree was. RESULTS: In lidocaine-treated group, the incidence of postintubational sore throat was less compared to control group significantly. There was no difference in incidence of hoarseness between two groups. CONCLUSION: Endotracheal cuff filled with lidocaine and sodium bicarbonate mixture is suggested as an effective protective method that reduces the frequency of postintubational sore throat.
