What Researchers Did
Researchers investigated the effects of hyperbaric oxygen therapy (HBOT) on wound healing in a diabetes-impaired pressure ulcer rat model.
What They Found
Capillary venous oxygen saturation significantly increased in the HBOT group on day 24, while haemoglobin in micro-blood vessels significantly decreased on days 21 and 42. Blood flow in microcirculation showed variable changes, increasing on days 17, 21, and 31 but decreasing on days 24 and 28. Inflammation, measured by CD68 counts, significantly decreased in the HBOT group on day 42, and wound breaking strength showed a trend for increase.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor did it involve Canadian researchers or patients.
Study Limitations
A key limitation is that this study was conducted in a rat model, meaning the findings may not directly translate to human patients.
