  • Ventilator-associated events (number of events)

    28 days

  • +15 more other outcomes

Study Arms (2)

AnapnoGuard group

EXPERIMENTAL

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

Device: Continuous cuff pressure regulationDevice: Automatic subglottic secretion drainageDiagnostic Test: Tracheobronchial colonization assessmentDiagnostic Test: Microaspiration assessmentDiagnostic Test: VAP assessment

Control group

ACTIVE COMPARATOR

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

Device: Intermittent cuff pressure regulationDevice: Manual subglottic secretion drainageDiagnostic Test: Tracheobronchial colonization assessmentDiagnostic Test: Microaspiration assessmentDiagnostic Test: VAP assessment

Interventions

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)

AnapnoGuard group

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

Control group

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)

AnapnoGuard group

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

Control group

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

AnapnoGuard groupControl group

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

AnapnoGuard groupControl group
VAP assessmentDIAGNOSTIC_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

Model Details: 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.
