What Researchers Did
Researchers designed a prospective, double-blind, randomized controlled trial to compare hyperbaric oxygen therapy plus standard wound care with standard wound care alone for preventing major amputations in diabetic patients with chronic lower limb ulcers.
What They Found
As this is a study protocol, no results are available yet; however, researchers planned to recruit 118 patients (59 per arm) with non-healing diabetic lower limb ulcers.
The primary outcome will be freedom from major amputation (below knee or metatarsal level) up to 12 weeks after randomization.
What This Means for Canadian Patients
If proven effective, adjunctive hyperbaric oxygen therapy could offer Canadian patients with diabetic foot ulcers a new treatment option to reduce the risk of major lower limb amputations.
This could lead to improved quality of life and reduced healthcare burden associated with amputations for this vulnerable population.
Canadian Relevance
This study was designed by Canadian researchers and planned to recruit patients from the Judy Dan Research and Treatment Centre in Canada.
The findings, once available, will directly inform clinical practice and guidelines for diabetic foot ulcer management within the Canadian healthcare system.
Study Limitations
As this is a study protocol, the actual efficacy and generalizability of hyperbaric oxygen therapy for diabetic foot ulcers remain to be determined upon completion and analysis of the trial.
