What Researchers Did
Researchers investigated the outcomes of 32 patients with gas gangrene and 11 patients with perineal necrotizing fasciitis who received hyperbaric oxygen therapy in addition to standard treatments like surgery and antibiotics.
What They Found
Among 32 patients with clostridial gas gangrene, the overall mortality rate was 28%, with 6 of 17 patients with myonecrosis and 3 of 15 patients with cellulitis dying. For the 11 patients with perineal necrotizing fasciitis (Fournier's gangrene), one patient died, and six required a colostomy.
What This Means for Canadian Patients
For Canadian patients facing severe infections like gas gangrene or Fournier's gangrene, this study suggests that hyperbaric oxygen therapy, when combined with surgery and antibiotics, may contribute to improved survival rates. This highlights the potential for HBO as a valuable adjunctive treatment to mitigate the high mortality associated with these rapidly progressing and often fatal conditions.
Canadian Relevance
This study covers clostridial gas gangrene and necrotizing soft tissue infections, both of which are Health Canada-recognized indications for hyperbaric oxygen therapy.
Study Limitations
The clinical study was retrospective and observational, lacking a control group to directly assess the independent contribution of hyperbaric oxygen therapy.
