Abstract
We studied ischemia and reperfusion in island groin flaps for nine Charles River rats. When the artery and/or vein are clamped, the oxygen saturation of hemoglobin (StO2) measured by an infra-red spectroscopic device (ViOptix, Inc., Fremont, CA) dropped significantly. The drop in arterial occlusion was usually faster than that in venous occlusion. When the clamp was released after more than 1 hour of vessel occlusion, the StO2 value came back, typically not to the pre-occlusive level but only about half of it.
