对有雷诺现象(白指现象)6名链锯工分别于一九六六年一月和一九六八年四月进行了职业病调查。因为六六年前6名工人均乘自行车上下班,在六七年改为专车。所以在六八年调查时发现该6人的雷诺现象明显地减轻和消失。同时看到末梢循环和神经机能继续恶化。作者认为:雷诺现象是末梢循环机能紊乱的一种表面现象。在振动影响末梢循环机能一定程度时,一旦有某种诱因存在,如寒冷时,往往可诱发出雷诺现象。至于诱因还有那些,尚需进一步探讨。反映末梢循环机能的客观指标:如寒冷血管扩张反应、冷却后的平均皮肤温和冷却
Six chainsaw workers with Renault (white-finger phenomenon) conducted occupational disease surveys in January 1966 and April 1968 respectively. Because six workers were commuters by bicycle six or six years ago, they switched to special vehicles in six or seven years. Therefore, in the investigation of 1986, it was found that the Renault phenomenon of the six people obviously reduced and disappeared. At the same time see the peripheral circulation and neurological function continues to deteriorate. The author thinks: Renault phenomenon is a surface phenomenon of peripheral circulatory dysfunction. In the vibration of the peripheral circulation function to a certain extent, once there is some incentive, such as the cold, can often induce a Renault phenomenon. As for the incentives there are those that need further study. Reflect the peripheral circulation function of objective indicators: such as cold vasodilator response, the average cooling skin gentle cooling
