激光从业人员心血管系统的职业影响

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,为其安全防护提供参考.方法对154名专职从事激光人员(激光组)和92名非激光对照人员(对照组)进行心血管系统健康状况的检查和比较;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、血脂激光组总胆固醇上升23名(14.9%),下降5名(3.2%);三酰甘油上升25名(16.2%);高密度脂蛋白胆固醇上升17名(11.0%),下降15名(9.7%);低密度脂蛋白胆固醇上升27名(17.5%),下降14名(9.1%)]和血液流变学5个方面数十项指标的检查的结果显示,激光组与对照组各项检查的异常率相近,两组比较,差异均无显著性意义(P＞0.05).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.

Occupational hazard on cardiovascular system in laser workers

AIM: To explore the possibilitles of occupational hazards on cardiovascular system to people who work with laser for long term and provide advices about safety to them.METHODS: Health examination on cardiovascular system to 154 professional laser workers (laser group) and 92 non laser workers(control group)was caltied out to compare their health conditions; and the physical parameters of laser in the working environment were investigated.RESULTS: Scores of indexes of 5 aspects on blood pressure, electrocardiogram (ECG), peripheral blood cells, blood lipid and blood rheology had been testcd. In laser group, there were 23 cases who got increased values of total cholesterol (14.9% ) and 5 cases with decreased values (3.2%); 25 cases got higher values of triacylglycerol(16.2% ); 17 cases with higher value of high density lipoprotein(11.0% ) and 15 cases with lower (9.7%);there were also 27 cases got higher value of low density lipproteincholesterol(17.5% ) and 14 cases with lower value(9.1% ). Tile outcomes showed that there was no significant difference between laser group and control group on the abnormal rates of these indexes( P ＞0.05).CONCLUSION: There is no clear occupational hazard on cardiovascular system to people working witb laser.
