目的研究10℃的冷水复温试验(CWLT)在手传振动职业危害中的临床应用。方法以从事手传振动作业且诊断为职业性手臂振动病的42例患者为发病组,以从事手传振动作业但未能诊断为职业性手臂振动病的17名工人为接振组,以从事非手传振动作业的24名健康办公室人员为对照组。对3组人员进行10℃的CWLT,用数字皮温计测量CWLT前后手部皮温,并对结果进行统计分析。结果 3组工人手麻、手痛、手胀、手臂无力和关节疼痛的发生率分别比较,差异均有统计学意义(P<0.01)。3组手部主要症状的发生率从小到大依次为对照组<接振组<发病组。3组组间手部皮温差异有统计学意义(P<0.01);左手和右手皮温差异无统计学意义(P>0.05);CWLT前和CWLT后0、5、10、15、20、25、30 min 8个时间点间手部皮温差异有统计学意义(P<0.01);时间和组别之间存在交互效应(P<0.05);时间和手别之间、组别和手别之间均不存在交互效应(P>0.05);时间、组别和手别三者之间无交互效应(P>0.05)。交互效应进一步分析结果显示:无论左手还是右手,CWLT前3组皮温差异均无统计学意义(P>0.05);CWLT后0~30 min...
【英文摘要】
Objective To study the clinical application of 10 ℃ cool water loading test(CWLT) in evaluating occupational hazard of the hand-transmitted vibration. Methods Forty-two workers exposed to hand-transmitted vibration and diagnosed as occupational hand-arm vibration disease were studied as the onset group. Seventeen workers exposed to hand-transmitted vibration but not diagnosed as occupational hand-arm vibration disease were studied as the vibration exposure group. Twentyfour healthy workers unexposed to hand...
