The study design was a prospective, randomized, double blind. Ninety patients of either sex, ASA I and II were randomly divided into three groups according to the medium used for inflation of endotracheal tube cuff. The study was conducted to correlate the changes in intra­cuff pressure and post­operative incidence of tracheal morbidity in form of hoarseness, sore throat and dysphagia. We observed close relationship between rise in intracuff pressure and incidence of tracheal morbidity. The present study concluded that incidence of postoperative sore throat, hoarseness & dysphagia was significantly less (p 0.05) when Normal Saline & Lignocaine were used as medium for an endotracheal tube cuff inflation as compared to air.
