The purpose of this study is to test the efficacy of a novel cleaning device in keeping silver-coated endotracheal tubes free from bacterial colonization.
Several studies have suggested that biofilm formation inside the ETT plays a pivotal role in VAP development and drug-resistance induction. Silver-coated ETT have proven effective in delaying but not in preventing ETT colonization and biofilm formation, due to a barrier effect of biofilm and accumulated debris. Advanced ETT cleaning devices are able to remove debris and biofilm and reduce the total ETT microbial load to a certain extent. The Investigators hypothesize that the routine use of endOclear in patients intubated with a silver-coated ETT will reduce ETT microbial colonization. The Investigators therefore want to assess the reduction of ETT microbial colonization in patients intubated with a silver-coated ETT and cleaned with endOclear compared to the current standard of care of silver-coated ETT (blind suctioning). They plan to achieve this result by analyzing the tubes of each enrolled patient after it has been removed, either because the patient does not need it anymore due to his/her better clinical conditions, or because there is a need of tracheostomy or because he/she dies. Specifically they will analyze how the endOclear cleaning maneuver affects microbial colonization in the inner layer of the ETT and how this can determine distal airway inoculation and, ultimately, VAP development.
Specific AIM #1: Investigators will test the hypothesis that routine use of endOclear in patients intubated with a silver-coated ETT will reduce ETT microbial colonization.
Specific AIM #2: Investigators will test the hypothesis that keeping ETTs free from microbial colonization will prevent septic inoculation of distal airways
Specific AIM #3: Investigators will test the hypothesis that prevention of ETT biofilm development will reduce drug resistance rates found in ETT and distal airways isolates
The investigators will conduct a randomized clinical trial on 40 patients intubated with silver-coated ETT and randomized to receive standard ETT cleaning vs cleaning with the endOclear device.

| ETT cleaning maneuver | Device | EndOclear is a commercially available device. It consists of an endotracheal tube cleaning apparatus with a flexible central tube and a cleaning device at its distal end. In operation, the collapsed cleaning apparatus is inserted into the ETT through a Y-shaped connector. The device is then expanded by a safety toggle protected trigger mechanism that, when fired, presses the device's smooth silicone disc against the inside surface of the endotracheal tube. The cleaning apparatus is then pulled out of the endotracheal tube removing mucus deposits and secretions. We plan to add the use of endOclear to the standard ICU practice, scheduling the systematic use of the device every 8 hours for the whole intubation period. |
| Measure | Description | Time Frame |
|---|---|---|
| Endotracheal Tube Colonization | Discarded ETTs will be collected after extubation and sent for quantitative and qualitative microbiological analysis after silver ion inactivation. Qualitative analysis was based on confocal microscopy, we described visually the distribution of microbial colonization. However, we did not report numerical value because the confounding factors (i.e., number and length of devices). | At extubation (an expected average of 7 days) |
| Measure | Description | Time Frame |
|---|---|---|
| Microbiological Colonization of Distal Airways | Investigators will collect data about distal airways samples performed for clinical reasons during the study period and, in addition, investigators will collect a specimen from the distal airways immediately before extubation. | At extubation (An expected average of 7 days) |
