What Researchers Did
Researchers conducted a retrospective study in an intensive care unit to investigate if hyperbaric oxygen therapy was linked to ventilator-acquired pneumonia in patients on mechanical ventilation.
What They Found
Out of 182 patients on mechanical ventilation for over 48 hours, 42 (23%) developed at least one episode of ventilator-acquired pneumonia (VAP). While 124 (68%) of these patients received hyperbaric oxygen therapy (HBOT), the study found no association between HBOT and the occurrence of VAP. Independent risk factors for VAP included reintubation (OR: 8.3), intra-hospital transport (OR: 3.5), and the use of paralytic agents (OR: 3.3).
What This Means for Canadian Patients
For Canadian patients requiring mechanical ventilation, this study suggests that receiving hyperbaric oxygen therapy may not increase their risk of developing ventilator-acquired pneumonia. This finding could offer reassurance regarding the safety of HBOT in critically ill patients who might benefit from it for other conditions.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This was a retrospective observational study conducted in a single intensive care unit, which may limit how broadly its findings apply to other settings.
