A study was undertaken to compare two new methods of capillary blood flow measurement, namely fluorescein flowmetry (FF) and laser Doppler flowmetry (LDF). The blood flow was measured in a pelvic pouch during its construction and in the completed ileoanal anastomosis in 12 patients. There was a high correlation between the two methods (correlation coefficient, 0.78) (p less than 0.01) when the blood flow was measured in the pelvic pouch. The correlation coefficient between the two methods for the difference between the blood flow in the pelvic pouch at the site of the planned anastomosis when the pouch resided in the abdomen and that in the completed ileoanal anastomosis was r = 0.99 (n = 12, p less than 0.001); the reduction amounted to 25% as measured by FF and 27% as measured by LDF (n = 12, p less than 0.01). All ileoanal anastomoses healed perfectly, the lowest FF and LDF values being 0.004 density units/sec and 0.3 V, respectively. The results indicate that either method can be considered for measuring capillary blood flow.
开展了一项研究以比较两种测量毛细血管血流的新方法,即荧光素血流测定法(FF)和激光多普勒血流测定法(LDF)。对12例患者在盆腔袋构建过程中及其完成回肠肛管吻合术后的盆腔袋内血流进行了测量。在盆腔袋内测量血流时,两种方法之间存在高度相关性(相关系数为0.78)(p<0.01)。当盆腔袋位于腹腔内时,在计划吻合部位的盆腔袋内血流与完成回肠肛管吻合术后的血流之间,两种方法的相关系数为r = 0.99(n = 12,p<0.001);用FF测量减少量为25%,用LDF测量减少量为27%(n = 12,p<0.01)。所有回肠肛管吻合口均完美愈合,FF和LDF的最低值分别为0.004密度单位/秒和0.3 V。结果表明,两种方法均可用于测量毛细血管血流。
