作者对158例振动病患者脫离振动作业后的5年过程,进行了4次动态观察。患者主要接触局部振动(铆工、掘进工、采煤工、伐木工);使用各种型号的振动工具,接触振动的频率为29～100赫兹,振幅0.15～2.2毫米;多为30～49岁的男工,其振动作业工龄均在11年以上。病人的主诉多为手痛、手麻、手冷和头痛,少数有下肢麻木、疼痛和发冷。检查多见手部紫绀、大理石花纹、多汗、并有手套型的痛觉和触觉减退,都有不同程度的毛细血管痉挛、冷水试验时值延长和振动觉减低。脫离振动作业后5年的动态观察表明:虽经积极综合治疗,但未见完全恢复的病人;部分恢复者占20％,这部分病人无其他并发病,并且在脫离振
The author of 158 patients with vibration sickness out of vibration after 5 years of the process, carried out 4 dynamic observations. The main contact with the local vibration of patients (riveting workers, diggers, coal miners, lumberjacks); use various types of vibration tools, contact vibration frequency of 29 to 100 hertz, amplitude 0.15 to 2.2 mm; mostly 30 to 49 years old Of male workers, the vibration length of service in more than 11 years. Patients complained of hand pain, numbness, hand cold and headache, a handful of lower limb numbness, pain and chills. Check more common hand cyanosis, marble pattern, sweating, and a glove type of pain and tactile decline, have varying degrees of capillary spasm, Lengthening test value and reduce vibration. The dynamic observation of 5 years after out-of-vibration operation showed that although the active treatment did not achieve complete recovery, 20% of those who recovered partially did not have any other complications,
