Randomized Controlled Trial Clinical Trial[Efficacy of topical administration of lidocaine through a Malinckrodt Hi-Lo Jet tube in lessening cough during recovery from general anesthesia].
To achieve tracheal anesthesia during intubation, an endotracheal tube was purposely designed. The tube had multiple laser-induced perforations in its lower portion produced that allowed administration of the local anesthetic in a pulverized form. We evaluated the efficacy of lidocaine 2% in preventing cough during recovery from general anesthesia. ⋯ At the end of the anesthesia period, the presence of cough was treated with the test solution. In 90% of cases treated with lidocaine, cough disappeared in about 30 seconds and patients tolerated the endotracheal tube until extubation was performed. All patients who received saline solution presented cough until extubation.
