局部振动病是长期使用振动工具而引起的以末梢循环障碍为主的疾病,亦可累及肢体神经及运动功能。其典型表现为发作性手指变白。以往病例报告多数来自苏联、加拿大、日本及我国北方寒冷地区。近年来的流行病学研究发现亚热带地区长期接触振动的工人亦可患本病。我室1985年以来,在凿岩工局部振动病流行病学研究中确诊85例。 诊断主要根据有职业史1年以上;接振后手指遇冷变白,经诱发试验证实;因限于普查条件,未作肌电图检查。其次根据家族史,接振前无类似现象以及其他临床特征排除非职业因素所致的雷诺现象。85例均为 Local vibration disease is the long-term use of vibration tools caused by peripheral circulation disorders of the disease, can also affect the limb nerve and motor function. The typical performance of the fingers of the finger whiten. Most of the past case reports from the Soviet Union, Canada, Japan and China’s northern cold areas. Epidemiological studies in recent years have found that workers exposed to vibrations in subtropical regions may also develop this disease. Since 1985, my room has been diagnosed 85 cases in the epidemiological study of local vibration disease of rock drilling workers. Diagnosis is mainly based on a history of more than 1 year; after the vibration of the fingers cold white, confirmed by induced test; due to limited census conditions, no electromyography. Second, according to family history, no similar phenomenon before the vibration and other clinical features exclude non-occupational factors caused by the phenomenon of Renault. 85 cases were
