作者用无损伤性经皮连续测定动脉血氧分压的装置放在左前腕,观察白指发作的振动工具使用者7例(男性,接振4～34年)在冷水浸渍(5℃、10分钟)时的手指及前腕的皮温及前腕tcpo_2的变化,并与7名无振动工具使用史的健康男子对照,得以下结果: (1)有白指的振动工具使用者,冷水试验5分钟后手指皮温不上升,缺乏健康对照者所产生的寒
The authors used noninvasive percutaneous continuous arterial oxygen pressure device on the left anterior wrist and observed the use of vibration tools in white fingers. Seven patients (male, 4 to 34 years old) were exposed to cold water immersion (5 ℃, 10 Minutes), the change of skin temperature and anterior wrc tcpo_2 of the fingers and anterior wrists was compared with that of 7 healthy men without history of vibrational tools, and the following results were obtained: (1) user of the vibration tool with white fingers, cold water test for 5 minutes After the finger skin temperature does not rise, the lack of healthy controls produced by the cold
