What Researchers Did
Researchers reported a rare case of pulmonary decompression illness ('Chokes') in a 60-year-old man who developed severe respiratory failure and shock after diving.
What They Found
They found the patient presented with extreme vascular hyperpermeability and a high serum procalcitonin (PCT) level of 20.24 ng/mL. Despite extensive fluid therapy, severe intravascular dehydration and shock persisted, suggesting endothelial damage and increased inflammatory cytokines.
What This Means for Canadian Patients
This case highlights the severe and rapid progression of pulmonary decompression illness, underscoring the critical need for immediate recognition and aggressive management in affected individuals. Procalcitonin might be a useful stress marker for endothelial damage and severity in such diving-related emergencies.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a single case report, the findings of this study are not generalizable to a broader patient population.
