What Researchers Did
Researchers conducted a systematic review and pooled analysis of randomized controlled trials to evaluate hyperbaric oxygen therapy (HBOT) for chronic wounds.
What They Found
Six studies were included in the review. Pooled data from five trials (118 patients) on diabetic ulcers showed HBOT significantly reduced the risk of major amputation (Relative Risk: 0.31; Number Needed to Treat: 4). However, HBOT did not affect ulcer healing or minor amputation rates, and data for venous, arterial, or pressure ulcers were limited.
What This Means for Canadian Patients
For Canadian patients with diabetic foot ulcers, hyperbaric oxygen therapy may offer a practical benefit by reducing the risk of major amputation. Patients should discuss this treatment option with their healthcare providers to determine its suitability for their specific condition.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.
Study Limitations
A significant limitation is the lack of appropriate trials for arterial and pressure ulcers, and limited data for venous ulcers, restricting the generalizability of HBOT benefits across all chronic wound types.
