Blood flow was investigated in 112 skin flaps (84 delayed and 28 undelayed) in 28 pigs. The flow was significantly (P less than 0.001) increased over the control flow with increasing delay intervals, reaching the greatest flow at one week after the delay (paralleling the increase in tissue survival). This increased blood flow persisted after definitive flap raising. The circulatory adjustments within the first week of the delay constitute the delay phenomenon, and they determine the ultimate viability of the skin flap in this model.
对28头猪的112个皮瓣（84个延迟皮瓣和28个未延迟皮瓣）的血流情况进行了研究。随着延迟间隔时间的增加，血流较对照血流显著增加（P<0.001），在延迟后一周达到最大血流（与组织存活率的增加平行）。在皮瓣最终掀起后，这种增加的血流持续存在。延迟第一周内的循环调节构成了延迟现象，并且它们决定了该模型中皮瓣的最终存活能力。
