What Researchers Did
Researchers statistically re-analyzed data from two previous studies by Fife and Strauss to assess the validity of transcutaneous oxygen measurements (TCOMs) in predicting diabetic foot ulcer (DFU) healing with hyperbaric oxygen (HBO₂) therapy.
What They Found
In the Strauss paper, among 143 subjects, 87.5% of diabetic foot ulcers healed when transcutaneous oxygen measurements (TCOMs) exceeded 200 mmHg with hyperbaric oxygen (HBO₂), even if room air TCOMs were below 30 mmHg (p < 0.001). The Fife paper, analyzing 221 patients, showed healing failure rates decreased from 35.7% to 14.3% as TCOMs with HBO₂ increased from 200 mmHg to 699 mmHg. Overall, both studies indicated that nearly 90% of diabetic foot ulcers healed if TCOMs exceeded 200 mmHg with HBO₂, irrespective of room air readings.
What This Means for Canadian Patients
Canadian patients with diabetic foot ulcers undergoing hyperbaric oxygen therapy may benefit from transcutaneous oxygen measurements (TCOMs) to predict treatment success. This could help clinicians identify patients most likely to heal with adjunctive HBO₂ and tailor treatment plans accordingly.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation noted was the absence of statistical significance for specific TCOM ranges above 200 mmHg due to small subject numbers within those groupings, and the retrospective nature of the original studies.
