局部振动病是由于接触振动而引发的职业病,手的微循环障碍及手指发白是该病的主要特征,故也称为振动性白指,它是我国常见的一种职业病。冷水激发试验是诊断的重要依据,以往由于缺乏快速、动态、定量的微循环检测方法,因此只能以皮肤温度的变化作为反映微循环变化的间接指标。本文为国内首次利用激光多普勒方法对接触振动人群冷水激发试验的甲襞微循环进行动态、定量的观测,并就此进行了分析探讨。1 对象和方法1.1 对象 某厂铸工共48人,接触振动时间9～30年,年龄为
Local vibration disease is due to contact with occupational diseases caused by vibration, hand microcirculation and finger whitening is the main feature of the disease, it is also known as vibrating white fingers, it is a common occupational disease in our country. Cold water stimulation test is an important basis for diagnosis. In the past, due to the lack of rapid, dynamic and quantitative detection of microcirculation, changes in skin temperature can only be used as indirect indicators of changes in microcirculation. This paper is the first time that the laser Doppler method is used in China to conduct dynamic and quantitative observation of the microcirculation of formazan microcirculation in cold water challenge test of contact vibrational population. 1 objects and methods 1.1 Object A cast a factory a total of 48 people, vibration contact time 9 to 30 years, the age
