What Researchers Did
Researchers investigated how hyperbaric oxygen therapy (HBOT) affected the survival of skin flaps in rats that had been exposed to tobacco smoke for two months.
What They Found
The HBOT group, which received seven daily sessions of HBOT at 2 ATA for 90 minutes, showed a significantly increased viable flap area (84%) compared to the control group (47%). HBOT also led to an increase in appendage units and angiogenesis density, and a decrease in iNOS levels, though it did not alter VEGF-a levels.
What This Means for Canadian Patients
For Canadian patients who smoke and are undergoing surgeries involving skin flaps, these findings suggest that HBOT could potentially improve the survival rate of these flaps. This could lead to fewer complications and better healing outcomes for individuals requiring reconstructive procedures.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A limitation of this study is that it was conducted on rats, meaning the findings may not directly apply to human patients.
