Endotracheal Tubes for Prevention of Ventilator-associated Pneumonia (PreVent)
Researchers are looking at three different types of breathing tubes to see if any of them are better at preventing pneumonia than the others. Two of the tubes have design features to prevent leakage of fluids from the mouth and throat into the lungs. This is importance, since leakage of small amounts of fluid into the lungs may lead to pneumonia. The third tube is the standard tube used at most hospitals.
The hypothesis is that the use of a breathing tube that reduces fluid leakage into the lungs will reduce the risk of developing pneumonia, compared to the standard tube. The study will also look at the safety of the modified breathing tubes, compared to the standard tube.
This study is a small, "pilot" study that will determine if it is possible to perform a larger study that will provide more certain results.
