The present investigation was designed to clarify what induces circulatory enhancement in the delay procedure. Two different sizes of a bipedicle flap were prepared in rats and the blood flow was measured at the centre of the flaps. The delay effect, that is, elongation of the survival length, was significantly less in the wide flap than in the narrow flap, though the two flap groups had almost identical levels of central ischaemia when averaged for each group. On the basis of ischaemic level, the flaps, regardless of size, were classified into two groups: more and less ischaemic than the mean. The delay effects noted in the more ischaemic flaps were not significantly different from those in the less ischaemic flaps. These results indicate that flap width has more influence on the delay effect than the degree of ischaemia.
本研究旨在阐明在延迟手术过程中是什么导致了循环增强。在大鼠身上制备了两种不同大小的双蒂皮瓣,并在皮瓣中心测量血流量。延迟效应,即存活长度的延长,在宽皮瓣中明显小于窄皮瓣,尽管两组皮瓣平均每组的中心缺血水平几乎相同。根据缺血水平,皮瓣无论大小都被分为两组:缺血程度高于和低于平均值的。缺血程度较高的皮瓣的延迟效应与缺血程度较低的皮瓣的延迟效应没有显著差异。这些结果表明,皮瓣宽度对延迟效应的影响比缺血程度更大。
