What Researchers Did
Researchers analyzed 132 patients admitted with a diagnosis of gas gangrene between 1970 and 1980, all of whom underwent immediate surgery followed by hyperbaric oxygen therapy.
What They Found
Of the 132 patients, 54 did not have bacteriological evidence of Clostridium perfringens. Among the 78 patients with proven gas gangrene, the overall mortality rate was 38%, and amputation after limb injuries occurred in 55% of cases, with no clear advantage observed for hyperbaric oxygenation regarding the death rate.
What This Means for Canadian Patients
Canadian patients diagnosed with gas gangrene may face significant risks, including a high mortality rate and the potential for limb amputation, even with immediate surgical intervention and adjunctive therapies. The effectiveness of hyperbaric oxygen therapy in improving survival for these patients remains uncertain based on this study.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
This study is limited by its retrospective design, lack of a control group for hyperbaric oxygen therapy, and its age, reflecting practices from 1970-1980.
