Incidence of postoperative sore throat and cough: comparison of a polyvinylchloride tube and an armoured tube
© BioMed Central Ltd 2008
Published: 13 March 2008
One of the common postoperative complications is sore throat and cough. A number of factors may be responsible, namely direct trauma by the airway, the endotracheal tube, and mucosal damage caused by pressure by the cuff hyperinflated by N2O. This complication is minor but distressing to an otherwise healthy patient; different strategies have been proposed to prevent it. They include changes in the technique of intubation, in the endotracheal tube material, and lower cuff pressure.

Frequency of cough and sore throat
The frequency of postoperative sore throat and cough was greater with the use of the polyvinylchloride endotracheal tube.
The study demonstrates that the use of a polyvinylchloride endotracheal tube was associated with a significantly higher incidence of postoperative sore throat and cough.
