局部振动可引起末梢血管机能和形态的改变,尤其是振动性自指的出现,已被公认为局部振动危害的典型表现。因此,末梢循环机能的检查对于评价局部振动危害,特别是对局部振动病的早期诊断具有重要意义。国内外对于局部振动危害引起的外周循环障碍进行了许多研究,检查方法也不断改进。近年,我们应用超声多普勒检查结合冷水负荷试验评价局部振动危害,获得初步结果,现报道如下。研究对象和方法研究对象为砂轮磨光接触局部振动的工人共
Local vibration can cause changes in peripheral vascular function and morphology, especially the emergence of vibration self-reliance, has been recognized as a typical manifestation of local vibration hazards. Therefore, the examination of peripheral circulatory function is of great significance for the assessment of local vibration hazards, especially for the early diagnosis of local vibration disease. At home and abroad, many studies have been conducted on peripheral circulation disorders caused by local vibration hazards, and inspection methods have been continuously improved. In recent years, we applied ultrasound Doppler examination combined with cold water load test evaluation of local vibration hazards, to obtain preliminary results are reported below. The research objects and methods are studied by a total of workers who grind the grinding wheel in contact with local vibration
