目的了解煤矿工人血液流变学变化情况,探讨引起血液流变学增高的原因及查找对策。方法将1 623例门诊检查血液流变学的体检者,分成实验组(煤矿工人组)和对照组(非煤矿工人组),分析两组各年龄段血液流变学变化情况,比较两组血液流变学总体增高情况;实验组血液流变学变化与煤矿工人井下作业工作年限、接触煤粉尘量、合并肺部疾病关系,统计学分析采用χ2检验。结果煤矿工人组血液流变学总体增高率为53.33%,明显高于非煤矿工人组的27.91%(P<0.01);血液流变学增高随煤矿工人井下工作年限、接触煤粉尘量的增加而呈上升趋势;血液流变学与伴有肺部疾病密切相关(P<0.05)。结论煤矿工人血液流变学总体水平偏高,血液粘度相应增高,易合并心脑血管疾病,严重影响煤矿工人生活质量,及时改善生产环境、加强个人防护、加强宣传至关重要。
Objective To understand the changes of hemorheology in coal miners and to explore the causes of hemorheology and the countermeasures. Methods A total of 1 623 outpatients with hemorrheological examination were divided into experimental group (coal miners group) and control group (non-coal miners group), the changes of blood rheology of the two groups were analyzed, Rheological changes in the overall situation; experimental group, changes in the degree of rheology and coal miners working hours downtime, exposure to dust coal, lung disease, statistical analysis using χ2 test. Results The overall increase rate of hemorrheology in coal miners was 53.33%, significantly higher than that in non-coal miners (27.91%) (P <0.01). The hemorrheology increased with the working life of coal miners and the contact dust (P <0.05). Hemorheology was closely related to lung diseases (P <0.05). Conclusion The overall level of hemorheology in coal miners is relatively high, the viscosity of blood is correspondingly increased, and it is easy to combine with cardiovascular and cerebrovascular diseases. Coal miners' quality of life is seriously affected, and the production environment is improved promptly. Personal protection is strengthened and publicity is strengthened.
