What Researchers Did
Researchers conducted a meta-analysis of 29 randomized controlled trials involving 1764 patients to evaluate the efficacy of hyperbaric oxygen therapy (HBOT) for diabetic foot ulcers (DFU).
What They Found
They found that HBOT significantly increased the complete healing rate of DFUs (46.76% vs. 24.46%) and decreased the amputation rate (26.03% vs. 45.00%) compared to conventional treatment. However, HBOT also significantly increased the incidence of adverse events (17.37% vs. 8.27%), with no significant difference in mortality.
What This Means for Canadian Patients
Canadian patients with diabetic foot ulcers may experience improved healing and reduced need for amputation with hyperbaric oxygen therapy. However, they should be aware of a higher risk of adverse events associated with this treatment.
Canadian Relevance
This study did not include any Canadian participants or research sites, so its direct Canadian relevance is not established.
Study Limitations
A limitation of this meta-analysis is the potential for heterogeneity among the included studies and varying quality of the original RCTs.
