| Abstract: |
OBJECTIVE: The present study aimed to compare the effect of topical laryngeal lidocaine with intravenous lidocaine before endotracheal intubation on the incidence and severity of postoperative sore throat, hoarseness, and cough. PATIENTS AND METHODS: This prospective randomized controlled study enrolled 144 patients undergoing laparoscopic cholecystectomy with endotracheal intubation. The patients were randomized to three groups and received 2% lidocaine by topical laryngeal spray (group T), intravenous 2% lidocaine (group I), and the equivalent volume of intravenous saline (group C) before intubation. The incidence and severity of sore throat, hoarseness, and cough reaction at 0.5, 1, 6, and 24 h after extubation were collected. RESULTS: The incidence of sore throat was significantly lower in group T than in groups I and C (6.4% vs. 37.2% and 86.7%, p < 0.001), respectively at 0.5 h after extubation, and it was significantly lower in group I than that in group C (37.2% vs. 86.7%, p < 0.001). Both the incidence of hoarseness and cough were significantly lower in group T than in group I and in group C (14.9% vs. 97.7% and 97.8%, p < 0.001, and 19.1% vs. 72.0% and 93.3%, p < 0.001), respectively. The severity of sore throat, hoarseness and cough in group T was significantly lower than that in group I and that in group C (p < 0.05), and it was significantly lower in group I than in group C (p < 0.05). CONCLUSIONS: Both topical laryngeal lidocaine and intravenous lidocaine before intubation have positive effects on preventing sore throat. Topical laryngeal route was superior to intravenous route.
