Abstract
Objective: We aimed to evaluate whether endotracheal tube (ETT) intracuff lido¬caine 2% was superior to saline in blunting emergence coughing, postoperative sore throat, and hoarseness in patients undergoing elective minor to moderate risk surgeries.
Methods: In our prospective, double-blind trial; we enrolled 90 patients undergoing surgery under general anesthesia. Patients were randomly allocated to receive either ETT intracuff 2% lidocaine (L group), or ETT intracuff 0.9% saline (S group) versus ETT intracuff air (Control group). The ETT cuff was inflated to achieve a cuff pressure that prevented air leak during positive pressure ventilation. Incidence of emergence coughing, sore throat, and hoarseness were analyzed. The volume of inflation solution, the intracuff pressure, the duration of anes¬thesia, the time elapsed to extubation after discontinuation of anesthesia, and the volume of the inflation solution and the air withdrawn from the ETT cuff were also recorded.
Results: Intracuff 2% lidocaine was superior to saline in blunting emergence coughing (p 0.017). The incidence of sore throat was significantly lower in the L group at the post-anesthesia care unit (PACU) and at 24 hours after extubation (p < 0.001). Incidence of hoarseness was similar in both groups.
Conclusion: The present study demonstrated that the intracuff 2% lidocaine was superior to saline in decreasing the incidence of emergence coughing and sore throat during the postoperative period in patients undergoing elective minor to moderate risk surgeries
