我们应用激光多普勒血流仪对家兔带蒂皮瓣形成术前、后及断蒂后４８ｈ微循环血流进行测量。结果表明：①于皮瓣形成术后测量皮瓣中点血流量，实验组均高于对照组，提示山莨菪碱可以增加皮瓣的血流量。②皮瓣蒂部阻断后，中点ＬＤＦ值达到阻断前的５０％水平时断蒂，皮瓣不一定最终存活，应结合其他指征综合分析。 We used laser Doppler flowmeter to measure the microcirculation blood flow in 48 hours after the pedicle flap formation in rabbits before and after the operation. The results showed that: ①After skin flap formation, the midpoint blood flow in the flap was measured. The experimental group was higher than the control group, which suggested that anisodamine could increase the blood flow of the flap. ② pedicle pedicle block, the midpoint LDF value reached 50% of the level before the block off, the flap may not eventually survive, should be combined with other indications comprehensive analysis.
