Alkalinization of Intracuff Lidocaine Improves Endotracheal Tube-Induced Emergence Phenomena

Abstract

Use of 40 mg of alkalinized lidocaine, rather than lidocaine or air, to fill the endotracheal tube cuff reduces the incidence of sore throat in the postoperative period. This approach also decreases hemodynamic effects, restlessness, dysphonia, and hoarseness.
