超声波探伤作业对神经行为功能的影响

Influence of Ultrasonic Inspection Performance on Nerve Behavior and Function

目的探讨超声波探伤作业对神经行为功能的影响。方法采用WHO推荐的神经行为核心测试组合(Neu-robehavioural Core Test Batteries,NCTB),对56名超声波探伤作业工人(观察组)和56名无职业病暴露的行政人员(对照组)的情感状态(POMS)、简单视觉运动反应时、数字跨度、手提转捷度、数字译码、Benton视觉保留、目标追踪测试Ⅱ等进行测试。结果在情感状态测试中,观察组精力充沛得分低于对照组(P<0.05),疲劳、困惑得分高于对照组(P<0.05);行为功能测试中,观察组数字跨度、视觉保留项得分均低于对照组(P<0.01或P<0.05)。二组有差异的各项中,男性观察组紧张、忧郁、疲劳项得分高于对照组(P<0.05或P<0.01);女性只有目标追踪Ⅱ中错误打点数观察组高于对照组(P<0.05)。<10年工龄时,观察组情感状态中紧张、疲劳项得分高于对照组(P<0.05或P<0.01),精力充沛项得分低于对照组(P<0.05),行为功能中视觉保留得分低于对照组(P<0.05),手提转捷度顺手项得分高于对照组(P<0.01);≥10年工龄时,观察组数字跨度得分低于对照组(P<0.01)。结论超声波探伤作业对神经行为功能有一定的影响,尤其是对男性作业工人;接触工龄与神经行为功能效应关系不明显。

Objective To determine the influence of ultrasonic inspection performance on nerve behavior and function. Methods Fifty six ultrasonic inspection workers （experiment group） and fifty six control staffs （ control group） were recruited. Using Neurobehavioural Core Test Batteries recommended by WHO, different indexes were compared including affective state, simple visual sense motor reaction time, number span, hand raise and turn prompt degree, number transcode, Benton vision remaining, target tracing Test Ⅱ. Results In emotion state verification, energetic score of experiment group was lower than that of control group （P 〈 0. 05） , weary the puzzled scores were higher than that of control group（ P 〈 0. 05）. In behavior function testing, number span and vision remaining score of experimem group were lower than that of control group （P 〈 0. 01 or P 〈0. 05）. In items with significant differences between the 2 groups, the scores of intense, melancholy, and the weary of male in experiment group were higher than that of control group （ P 〈 0. 05 or P 〈 0. 01 ）. In target tracing Test Ⅱ , to arrange the number, the female in experiment group was higher than that of control group （P 〈0.05）. When 〈 10 years job seniority, the emotion condition intense, and the weary scores in experiment group were higher than that of control group（P 〈0. 05 or P 〈0. 01 ） , but the energetic score was lower than that of control group （ P 〈 0. 05 ）, while in the behavior function, the vision remaining score was lower than that of control group （ P 〈 0. 05 ）, and the hand raise and turn prompt degree convenient score was higher than that of control group（ P 〈 0. 01 ）. When≥ 10 years job seniority, the number span score of experiment group was lower than that of control group （P 〈 0. 01 ）.Conclusion There are significant influences of ultrasonic inspection performance on nerve behavior and function, especially to male workers. The relationship between working time and influence of ultrasonic inspection performance on nerve behavior and function is not significant.
