Continuous regulation of tracheal cuff pressure did not prevent ventilator-associated pneumonia (VAP) in severe trauma patients. Routine care was as effective as the pneumatic device in reducing VAP incidence.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Trauma Surgery
Background:
- Ventilator-associated pneumonia (VAP) is a common healthcare-associated infection in critically ill patients.
- Aspiration around the tracheal tube cuff is the primary VAP contamination route.
Purpose of the Study:
- To determine if continuous tracheal cuff pressure regulation prevents VAP in severe trauma patients.
- To compare a pneumatic device to routine manual assessment for VAP prevention.
Main Methods:
- An open-label, randomized controlled superiority trial in 13 French ICUs.
- Adults with severe trauma (ISS > 15) on mechanical ventilation for ≥48 hours were enrolled.
- Patients were randomized to continuous pneumatic regulation or routine manual cuff pressure monitoring.
Main Results:
- 73/216 (33.8%) in the intervention group and 64/218 (29.4%) in the control group developed VAP.
- No significant difference in VAP incidence between the groups (aHR, 0.96; 95% CI, 0.76-1.20; P = .71).
- No serious adverse events related to the pneumatic device were reported.
Conclusions:
- Continuous regulation of tracheal cuff pressure is not superior to routine care in preventing VAP.
- Current methods of tracheal cuff pressure management appear adequate for VAP prevention in this population.
