Coated Endotracheal Tube and Mucus Shaver to Prevent Hospital-Acquired Infections
|ClinicalTrials.gov Identifier: NCT00341354|

This study, conducted at the San Gerardo Hospital in Milan, Italy, will examine whether a bacteriocidal-coated endotracheal tube (breathing tube) cleaned with a device called a Mucus Shaver is safe and effective in preventing hospital-acquired infections in patients who require prolonged mechanical ventilation in an intensive care unit (ICU).
Pneumonia is the most frequent hospital-acquired infection in the ICU; its development is likely related to the use of a breathing tube. The tube is placed in the patient's trachea (windpipe) to assist breathing during and after an operation. Currently, breathing tubes in intubated patients are cleaned with a suction catheter that draws out secretions that accumulate in the tube. This method does not clean the tube completely, however, and within a few hours after the breathing tube is placed, bacteria may begin to grow inside the tube. Over time, as the patient breathes in and out through the tube, the bacteria may break free and enter the lungs, possibly causing pneumonia. In addition, the growth of bacteria in the tube decreases the size of the airway passage, making it more difficult to keep air moving in and out of the lungs.
Previous studies have shown that breathing tubes coated with silver-sulfadiazine prevented bacterial growth in the patient's airways and that use of the Mucus Shaver prevented accumulation of secretions in the lumen of the breathing tube, keeping the tube open. This study will determine if use of the coated tube and Mucus Shaver in patients requiring prolonged mechanical ventilation is safe and if it can reduce bacterial growth, the length of intubation and mechanical ventilation, the occurrence of pneumonia and the length of time in ICU and hospital.
Patients at San Gerardo Hospital who are 18 and older, who expect to have a breathing tube in place for more than 48 hours, and who are not allergic to silver-sulfadiazine may be eligible for this study.
Participants are randomly assigned to have either a standard breathing tube and standard cleaning or a coated tube cleaned with a Mucus Shaver. At intubation, a sample of secretions is collected from the mouth, the lumen of the breathing tube, and the airways. The lumen of the breathing tube is then cultured every day. When the tube is removed, or on the eighth day of intubation, a sample of secretions is collected from the mouth, the lumen of the breathing tube, and the airways. After the tube is removed, it is examined for biological and microscopic analysis.
