title: The effects of the perfusion of various solutions on the no-reflow phenomenon in experimental free flaps.
abstract: The effects of solution perfusion in the free epigastric flap of the rabbit, after normothermic ischemic periods of 8 hours or 12 hours, have been examined by operative microscopic and histological methods. A smaller group of animals was also studied in which the perfusion was done before the ischemic insult. An ischemia-related obstruction to the peripheral blood flow occurred in the absence of stagnant ischemic blood in this model. Although the 3 perfusion fluids studied were shown to penetrate to all levels of a flap after such an ischemic period, none of them had a beneficial effect on skin survival. However, the solution containing mannitol did have a protective effect on fat survival. Analogies between these experimental findings and the clinical situation are made, and the importance of the early diagnosis and treatment of ischemia in a flap is emphasized.
