Randomized Controlled Trial Comparative StudyPolyurethane does not protect better than polyvinyl cuffed tracheal tubes from microaspirations.
Mechanically ventilated patients are prone to develop ventilator associated pneumonia due to microaspirations of subglottic secretions around the endotracheal tube cuff (usually constructed of polyvinyl material). A novel polyurethane cuff has been designed to minimize these leakages. The aim of the study was to compare the tracheal sealing capacities between the two tubes. ⋯ These preliminary results suggest that both tubes are poorly effective in preventing microaspirations.
