What Researchers Did
Researchers studied 45 divers with spinal decompression sickness to see how MRI scans of their spinal cords related to their symptoms and recovery over time.
What They Found
Spinal cord lesions on MRI were significantly more common in divers with severe decompression sickness. Importantly, no lesions were found in any diver who experienced a favorable outcome, showing 100% specificity. Acute back pain was strongly linked to persistent neurological problems, with an odds ratio of 14.
What This Means for Canadian Patients
For Canadian divers experiencing spinal decompression sickness, an early MRI could help doctors predict their potential recovery. If a diver has acute back pain after surfacing or signs of spinal cord compression, it suggests a higher chance of severe injury and a longer recovery, which can help guide treatment plans.
Canadian Relevance
This study covers decompression sickness, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
This study was retrospective, meaning it looked back at past cases, and included a relatively small group of 45 divers.
