Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Multicenter, cluster randomized, controlled, open-label trial to assess if AnapnoGuard System can minimize tracheal microaspiration and the risk of ventilator-associated pneumonia when compared to standard treatment

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Maintaining the endotracheal tube (ETT) cuff appropriately inflated plays a crucial role in the management of intubated patients because overinflation may cause tracheal wall damage, ulcerations and stenosis, and underinflation may results in fluid leakage and ventilator-associated pneumonia (VAP).

During mechanical ventilation, secretions contaminated with oropharyngeal and gastric pathogens pool in the subglottic space (tracheal region between the ETT cuff and the vocal cords) and enter the lower airways via microaspiration.

Subglottic secretion drainage (SSD) reduces the incidence of VAP and can be performed intermittently or continuously, with varying efficacy and often causing secondary tracheal mucosa lesions.

AnapnoGuard (AG) ETT has three dedicated lines (two suction lines and one sensing/venting/rinsing line) and can be connected to the AG 100 System, a new device which provides high-sensitive capnography of subglottic space and consequent adjustment of cuff pressure, to avoid fluid leakage and overinflation. It also evacuates secretions from the subglottic space by simultaneously rinsing/venting this space using the ETT dedicated line.

The hypothesis is that AG System may reduce the incidence of microaspiration, bacterial tracheal colonization and consequently the risk of VAP when compared to standard treatment (ETT with manually performed secretion drainage and cuff pressure control).

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Multicenter cluster randomized controlled and open-label trial. Because intubation is an urgent intervention in critically ill patients patients with acute respiratory failure, individual randomization is considered too complex and we predetermined cluster of 9 consecutive patients, stratified by centers, with each cluster being assigned to one of the study groups.

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

AnapnoGuard group

Patients intubated with AnapnoGuard endotracheal tube (polyvinylchloride tube with ellipsoidal shape, thin wall polyurethane cuff with dual suction lines and an extra venting line) which is connected to AnapnoGuard 100 System

Group Type EXPERIMENTAL

Continuous cuff pressure regulation

Intervention Type DEVICE

Within 24 hours, AnapnoGuard tube will be connected to AnapnoGuard 100 control device. It includes an automatic high-sensitive subglottic capnograph which measures every few minutes the carbon dioxide level in the subglottic space. If the level of carbon dioxide is above the threshold (established by animal studies) the system will increase the cuff pressure by a formula, if the level is below the threshold, the system will decrease the cuff pressure by 1 mmHg. Variations of cuff pressure are allowed only between pressure limits set by the user (minimum and maximum)

Automatic subglottic secretion drainage

Intervention Type DEVICE

Within 24 hours, AnapnoGuard tube will be connected to AnapnoGuard 100 device control which provides continuous subglottic secretion drainage (two different suction lines) and venting/rinsing (a third dedicated line)

Tracheobronchial colonization assessment

Intervention Type DIAGNOSTIC_TEST

Tracheal aspirate will be performed after intubation and after 72 hours for microbiological colture

Microaspiration assessment

Intervention Type DIAGNOSTIC_TEST

Tracheal aspirates will be performed 72 hours after intubation, and collected in a predefined study center to measure pepsin and salivary amylase

VAP assessment

Intervention Type DIAGNOSTIC_TEST

Patients will be follow to detect clinical, radiological or microbiological signs of VAP. If suspected, a tracheal aspirate or a bronchoalveolar lavage is performed to confirm the diagnosis

Control group

Patients intubated with TaperGuard Evac endotracheal tube (polyvinylchloride conic cuff with additional lumen for subglottic secretion suctioning)

Group Type ACTIVE_COMPARATOR

Intermittent cuff pressure regulation

Intervention Type DEVICE

ET cuff pressure will be manually measured three times per day using a portable manometer, and kept constant within 20-30 cmH2O

Manual subglottic secretion drainage

Intervention Type DEVICE

Subglottic secretions will be manually drained with a 10 mL syringe, using the only dedicated lumen

Tracheobronchial colonization assessment

Intervention Type DIAGNOSTIC_TEST

Tracheal aspirate will be performed after intubation and after 72 hours for microbiological colture

Microaspiration assessment

Intervention Type DIAGNOSTIC_TEST

Tracheal aspirates will be performed 72 hours after intubation, and collected in a predefined study center to measure pepsin and salivary amylase

VAP assessment

Intervention Type DIAGNOSTIC_TEST

Patients will be follow to detect clinical, radiological or microbiological signs of VAP. If suspected, a tracheal aspirate or a bronchoalveolar lavage is performed to confirm the diagnosis
