What Researchers Did
Researchers conducted a systematic review and meta-analysis of 11 studies involving 729 patients to evaluate hyperbaric oxygen therapy as an adjunctive treatment for diabetic foot ulcers with peripheral arterial occlusive disease.
What They Found
The meta-analysis of four studies found that hyperbaric oxygen therapy significantly reduced major amputations from 26.0% in the control group to 10.7% in the HBOT group (risk difference -15%, P = .002), with a number needed to treat of 7. However, no significant differences were observed for minor amputations, mortality, or amputation-free survival.
What This Means for Canadian Patients
For Canadian patients with diabetic foot ulcers and peripheral arterial occlusive disease, adjunctive hyperbaric oxygen therapy could significantly reduce the risk of major lower extremity amputations. This treatment may offer a valuable option to improve patient outcomes and quality of life.
Canadian Relevance
There is no specific Canadian connection mentioned in this study.
Study Limitations
The review included studies with varying designs and only a subset of studies were suitable for quantitative meta-analysis, potentially limiting the overall strength of evidence.
