What Researchers Did
Researchers studied 116 patients with confirmed clostridial myonecrosis, treating them with a combination of hyperbaric oxygen therapy at 3 ATA and repeated surgical removal of dead tissue.
What They Found
The study reported an overall mortality rate of 50.8%, even though 80.1% of patients had severe toxicity when admitted. Survival rates varied significantly by the infection's location: 34.5% for proximal sites like the elbow or knee (55 patients), 88.6% for peripheral limbs (44 patients) where amputation was avoided in 21 cases, and 23.5% for abdominal infections (17 patients).
What This Means for Canadian Patients
For Canadian patients diagnosed with severe clostridial myonecrosis, also known as gas gangrene, this study suggests that a combined treatment of hyperbaric oxygen therapy and surgical debridement could be a beneficial approach. The findings indicate that the location of the infection may influence treatment outcomes, with better survival rates observed for infections in the limbs.
Canadian Relevance
This study covers clostridial myonecrosis (gas gangrene), which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
This study is a retrospective case series from 1995 and lacks a control group, making it challenging to compare the effectiveness of the treatment against other approaches.
