以电脑断层扫描照相术探测背部各经穴安全深度

Detecting the Safety Depth on Human Back Loci by Computer Tomographic Scanning

本研究以电脑断层扫描照相术探测背部(包括督脉、手太阳小肠经、足太阳膀胱经)各经穴的安全深度,依针炙学背部各穴位照片解剖学上的相关位置加以定位,量取此一定位之背部体表至胸腔肋膜层的距离作为安全深度指标,以成年人120例,依不同的身高、体重,将男、女性别分为过重、适中、过轻体型交叉六组进行研究。结果显示,背部各穴位,男性与女性在安全深度上均无显著的差异,但不同体型者,在各个相同穴位上,其安全深度有显著差异(P<0.01),因此我们以此研究确定了人体背部各穴位的安全深度,以供临床针灸医师参考应用,进而建立国人不同体型之背部各穴安全深度指标。

The study was carried out at Tri-Service General Hospital and Mackay General Hospital.The sample population of patient was totally 120.According to their body weight and height,they were divided into six groups with various sizes,i.e.normal,over and under-weighted adults,followed by sex differences.After computer tomographic scanning results from patients'body back,the relative acupuncture loci should be measured through their anatomical position,then the distance between surface of body back and thoracic pleura could be defined as its safety depth.For each locus of the groups,the mean and its confident interval could be found.The analysis of variance(ANOVA),t-test, and multiple regression were also calculated by means of computer. The results showed that there were no significant differences on body back loci within sex differences,but for different body sizes,there appeared statistically significant differences for each locus,(P<0.01),so the safety depth for each back locus have actually been proved.Not only these data provided more useful information for clinical practices,but also our standard safety depth for each loci on back can then be established.
