Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A primary goal for all ICUs is to shorten the time of MV, to decrease the incidence of ETT microbial colonization and ultimately VAP incidence. To meet this goal several airways technologies to maintain the ETT free from debris/bacteria have been developed in order to improve the current ventilator-liberation standards in intubated critically ill patients.
Based on preliminary laboratory, animal and clinical data, The investigators now wish to test the hypothesis that a novel commercially available ETT cleaning device can be effective in targeting two specific issues:
* Specific aim 1: To evaluate the mean difference in ETT luminal volume of ETTs cleaned with the novel cleaning device (EndOclear) vs. ETT cleaned in the standard manner.
* Specific aim 2: To determine whether ETTs cleaned with the novel device show a lower degree of microbial colonization for the entire period of mechanical ventilation.
Data about in-vivo respiratory mechanics measurements, microbial diversity and antibiotic resistance analysis, users' feedbacks and safety of the device will also be collected.
The investigators will conduct a clinical trial on 74 intubated patients randomized to receive standard ETT cleaning or cleaning with the EndOclear.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ETT cleaning manuver
Patients randomized to the treatment group will undergo an ETT cleaning maneuver with endOclear three times a day (every 8 hours) for the whole intubation period in addition to the standard of care.
ETT cleaning maneuver
EndOclear device will be used for ETT cleaning maneuver. This is a commercially available device. It consists of an ETT cleaning apparatus with a flexible central tube and a cleaning device at its distal end. The cleaning device has a mechanically expandable mesh structure which can be adapted to selectively move between a radially-collapsed position and a radially-expanded one. 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 ETT. The cleaning apparatus is then pulled out of the ETT removing mucus deposits and secretions.
We will add endOclear to the standard ICU practice, scheduling the systematic use of the device every 8 hours for the whole intubation period.
Standard of care
In the protocol no intervention is planned for the control group, which will therefore be treated with blind suctioning as per caregiver clinical decision.
