手臂振动对心率变异性及外周循环功能影响的研究

探讨手臂振动对作业工人心率变异性与外周循环功能的影响及二者之间的关系。「方法」对某金矿凿岩工人进行了心率变异性的评价指标ＳＤＡＮＮ、ＬＦ／ＨＦ分析，并测试了冷水试验前后作业工人的皮肤温度以及试验后５ｍｉｎ、１０ｍｉｎ的复温度。结论手臂振动造成的外周循环功能障碍可能与植物神经功能紊乱有一定关系。

The Effects of Hand-arm Vibration on the Heart Rate Variability and Peripheral Circulation in Drilling Workers in Gold Mine

Objective] To explore the effects of hand arm vibration(HAV) on the heart rate variability and peripheral circulation and the relationships between them.Methods] SDANN,LF/HF,skin temperature both before and after cool water test(CWT) and the recovery rate of skin temperature after CWT were measured in drilling workers in gold mine.Results] SDANN,the skin temperature both before and after cool water test(CWT) and the recovery rate of skin temperature after CWT had a decreasing tendency,which decreased mostly in workers with vibration induced white finger(VWF).LF/HF had an increasing tendency in drilling workers compared with that in control group.Conclusion] There is a certain relationship between vibration induced dysfunction of peripheral circulation and disorders of autonomic nerves.
