AbstractOne hundred and eighty-four patients were studied to elucidate the contribution of intracuff pressure and cuff type to the occurrence of sore throat and hoarseness after operation. The patients were allocated to one of the following groups: A = mask only; B = reusable Rüsch tube with intermittent cuff volume adjustment; C = reusable Rüsch tube without cuff volume adjustment; D = disposable Portex Blue Line tube with intermittent cuff volume adjustment; E = disposable Shiley Low Pressure tube with intermittent cuff volume adjustment. Nitrous oxide was a component of anaesthesia in all patients. Moderate or severe symptoms were recorded in 30-33% of the patients in groups C, D and E, contrasting with group B, in which these sequelae were seen in only 10% of patients (P less than 0.025). All sequelae occurred less frequently in group A than in any of the other groups (P less than 0.025). Women were more likely to develop sore throat after intubation than were men (P less than 0.01). A possible relationship between differences in cuff-trachea contact area is postulated.
