Skin-flap metabolism in rats: oxygen consumption and lactate production.
Overall glucose metabolism was evaluated by measuring the rate of oxygen consumption (QO2) and lactate production in the pedicle skin flaps of rats. Skin flaps exhibited increases in QO2 and lactate production in vitro. The distal portion of the flap is characterized by a greater deposition of glucose to lactate during the initial 3 days following flap elevation. The contribution of glycolysis and of the oxidative pathways to glucose metabolism in skin flaps approximates that in normal skin on day 7 postoperatively.
