作者对330名接振工人和94名条件均衡的对照者柞了指端血管脉波描记检查。结果表明:接振工人手指异常波形,重搏波消失、流入时间R(+)组,R(-)组百分率分别与对照组比较均有显著性差异;手指血流图流出时间、波幅高、波幅差接振组R(+)组、R(-)组百分率两组比均有非常显著性差异。提示局部振动工具对工人手指血管有损害作用。
The authors examined finger vein angiography on 330 surge workers and 94 well-matched controls. The results showed that: the abnormal waveform of finger, the disappearance of Doppler wave, the inflow time of R (+) group and the percentage of R (-) group were significantly different from those of the control group. The finger outflow time and amplitude were high, There was a significant difference between the two groups in R (-) group and R (-) group in amplitude difference vibration group. Prompt local vibration tools on the fingers of workers have a damaging effect on blood vessels.
