Sore throat and hoarseness are common complications after endotracheal intubation, with the incidence ranging from 6.6 to 90%. They may be distressing and leave the patient with an unpleasant memory of the operation. Incidence depends on various factors like age, sex, the size of the endotracheal tube, the cuff pressure, the duration for which the tube is in place, the time and manipulations needed to insert the tube, number of suctioning attempts and others.
ninthy patients were randomly allocated into3 groups. The ETT cuffs in each group were sprayed with beclomethasone, 10% lidocaine hydrochloride, or normal saline before endotracheal intubation. After insertion, the cuffs were inflated to an airway leak pressure of 25 cm H2O. The patients were examined for sore throat (none, mild, moderate, or severe) each 6 h to 24 hours after extubation. Occurance of cough, laryngospasm were continously monitored and recorded during the observational period.
