目的 :探讨长期从事激光工作的人员是否有心血管系统的职业危害 ,为安全防护提供参考。方法 :选择从事激光工作一年以上的职业人员 ,对其心血管系统的健康状况进行检查 ,并与对照组进行比较 ;对作业环境中激光物理参数进行调查。结果 :血压、心电图、外周血细胞、血脂和血液流变学 5个方面数十项指标的检查结果显示激光组与对照组各项检查的异常率相近 ,经χ2 检验 ,两组差异无显著性 (P>0 .0 5 )。结论 :从事激光工作人员的心血管系统无明显的职业危害影响 Objective: To explore whether long-term laser work personnel have occupational hazards of cardiovascular system and provide reference for safety protection. Methods: Professionals who engaged in laser work for more than a year were selected to check their cardiovascular system health and compare with the control group. The laser physical parameters in the working environment were investigated. Results: The blood pressure, electrocardiogram, peripheral blood cells, blood lipids and blood rheology dozens of indicators of the test results showed that the laser group and the control group of abnormalities similar to the various tests by χ2 test, the two groups showed no significant difference ( P> 0 .0 5). Conclusion: There is no significant occupational hazard in the cardiovascular system of laser workers
