What Researchers Did
Researchers evaluated the impact of glycemic control on wound healing in 22 diabetic patients undergoing hyperbaric oxygen therapy for lower extremity ulcers.
What They Found
Patients were divided into "good glycemic control" (n=12, mean HbA1c 6.5 ± 0.8%) and "poor glycemic control" (n=10, mean HbA1c 8.8 ± 1.4%) groups based on HbA1c levels at the start of hyperbaric oxygen therapy. After 20 sessions over 30 days, there was no significant difference in wound healing, measured by reduction in ulcer surface area, depth, or volume, between the two groups.
What This Means for Canadian Patients
Canadian patients with diabetic lower extremity ulcers may benefit from hyperbaric oxygen therapy regardless of their blood sugar control at the start of treatment. This suggests that treatment should not be delayed while attempting to optimize glycemic levels.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.
Study Limitations
A limitation of this study is its small sample size of 22 patients, which may limit the generalizability of the findings.
