Vegetable gum based gel lubrication of endotracheal tube cuffs improves efficacy of alkalinized intracuff lignocaine in preventing postoperative sore throat: a randomized controlled study

ABSTRACT

Background and aims: In order to reduce endotracheal tube [ETT] induced emergence phenomenon at extubation which involves postoperative sore throat [POST], cough, hoarseness, dysphagia and hemodynamic changes, we evaluated the efficacy of vegetable gum based [VGB] Lubic gel lubrication alone or in combination with 4% intracuff alkalinized lignocaine [IAL]. The vegetable gums in the gel appear to be of special significance:
