Effect of local application of transcutaneous carbon dioxide on survival of random pattern skin flaps

Skin flap procedures are widely used to reconstruct skin and soft tissue defects. Skin flap necrosis is a serious postoperative complication. Many researchers have introduced pharmacological agents to improve flap ischemia in experimental studies. However, these outcomes remain controversial. We previously demonstrated that transcutaneous CO2 application improves hypoxia in fracture repair. In this study, we hypothesized that improving hypoxia by transcutaneous CO2 application can improve the blood flow of skin flaps and increase angiogenesis.
