What Researchers Did
Researchers described two cases of cerebral arterial gas embolism (CAGE) complicated by pneumothorax during recompression therapy and reviewed similar cases from Royal Navy and United States Navy submarine escape tank training accidents.
What They Found
Both described cases of CAGE treated by recompression developed bilateral pneumothoraces; the first case, treated on an air table, required in-chamber thoracentesis, while the second case, treated on an oxygen table, did not. A review of similar accidents suggested that the danger of pneumothorax during recompression for CAGE might be overstated, and modern oxygen-based therapeutic recompression tables may significantly reduce this risk.
What This Means for Canadian Patients
If Canadian patients require recompression therapy for CAGE, particularly following barotrauma, treatment on oxygen-based tables may reduce the need for invasive procedures like thoracentesis. This approach could improve safety and outcomes for those undergoing such specialized medical interventions.
Canadian Relevance
This study has no direct Canadian connection as it focuses on Royal Navy and United States Navy submarine escape training accidents.
Study Limitations
The study's findings are based on a limited number of described cases and a review of similar incidents, which may not be generalizable to all clinical scenarios.
