Research Article: Effect of Esketamine Gargle on Postoperative Sore Throat in Patients Undergoing Double-Lumen Endobronchial Intubation: A Randomised Controlled Trial

Date Published: 2023-10-19

Abstract:
Postoperative sore throat commonly occurs after tracheal intubation and ranks sixth among adverse outcomes associated with general anaesthesia., Evidence indicates that a large-sized tracheal tube is a potential risk factor for postoperative sore throat., Because of their larger external diameters, double-lumen endobronchial tubes, which are widely used in surgeries that require bronchial blockage and one-lung ventilation, may induce postoperative sore throat more often than single-lumen tracheal tubes. Postoperative sore throat usually worsens during swallowing and is difficult to treat, even if wound pain is well managed with narcotics. Thus, efforts are needed to prevent this complication in patients undergoing double-lumen tube intubation.
