What Researchers Did
Researchers conducted a scoping review to identify and compare gas-based therapies and evaluate their effectiveness in treating chronic wounds.
What They Found
The review included 54 clinical studies and 45 preclinical studies. While hyperbaric oxygen therapy and topical gas therapies showed some clinical use, their adoption was limited by costs and variable outcomes, whereas novel preclinical formulations like micro- and nanoparticle systems demonstrated improved chronic injury outcomes in models.
What This Means for Canadian Patients
Canadian patients with chronic wounds may eventually benefit from gas-based therapies, but current clinical applications face challenges regarding cost and consistent effectiveness. Further research into novel delivery methods, currently in preclinical stages, could lead to more accessible and effective treatments in the future.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
As a scoping review, this study identified the range of available evidence but did not critically appraise the quality of individual studies or provide a definitive synthesis of treatment efficacy.
