What Researchers Did
Researchers in Poland looked back at five years of data (2003-2007) on 51 recreational divers who received recompression treatment for diving injuries.
What They Found
Over five years, 51 recreational divers in Poland received recompression treatment for diving injuries. Symptoms appeared much faster for those with neurological decompression sickness or arterial gas embolism (median 0.2 hours) compared to other types of decompression sickness (median 2.0 hours). Initial treatment resolved symptoms completely for 24 divers, increasing to 37 divers after 1 to 20 additional hyperbaric oxygen sessions, with 12 cases still having some residual symptoms.
What This Means for Canadian Patients
This study reinforces that recompression treatment, including hyperbaric oxygen therapy, is effective for divers experiencing decompression illness or arterial gas embolism. Canadian divers who experience symptoms of decompression sickness, whether from local dives or after returning from tropical locations, should seek immediate medical attention for potential recompression treatment. Early treatment can lead to better outcomes, especially for serious neurological symptoms.
Canadian Relevance
Although this was a Polish study, it covers decompression sickness and arterial gas embolism, which are Health Canada-recognised indications for hyperbaric oxygen therapy.
Study Limitations
As a retrospective study, it relied on past records and did not use standardized treatment protocols, which could affect the generalizability of the findings.
