通过职业性健康监护结局的分析 ,观察有害因素低剂量下慢性职业危害特点 ,为采取相应临护对策提供医学依据。取经常性监测与监护中两个断面的暴露剂量与外周血异常 ,职业病与肿瘤发生资料作观察组的观察指标 ,以周期非有害作业人员作对照 ,用俘获再俘获法直接比较。观察组混苯与X射线的WBC下降的ACPR分别为 35 .9%、17.91% ,RR为 7.6 9、3 .84,对照组ACPR为 4.6 7% ;职业病与肿瘤的ACPR为 5 .75 %、2 .99% ,职业病RR为 1.9。对照组未见发生。外周血异常和职业病与肿瘤的ACPR与RR :混苯 >X射线 >对照组。混苯作业外周血下降及时调换工种 ,利于阻断职业病发生或加重 ,X射线组慢性损伤潜伏期较长 ,应加强有效防护
Through the analysis of occupational health care outcomes, we observed the characteristics of chronic occupational hazards under low doses of harmful factors and provided medical evidence for the corresponding measures of clinical support. Taking the exposure dose and peripheral blood abnormality, occupational disease and tumor occurrence data of two sections in routine monitoring and monitoring as the observational index of the observation group, the non-harmful workers in the cycle were taken as a control, and the capture and capture methods were compared directly. The ACPR of the WBC decreased in the observation group was 35.9% and 17.91% respectively, the RR was 7.69 and 3.84, while the ACPR in the control group was 4.6%. The ACPR of the occupational disease and the tumor was 5.75% 2.99%, occupational disease RR was 1.9. The control group did not happen. Abnormal peripheral blood and occupational diseases and tumor ACPR and RR: mixed benzene> X-ray> control group. Mixture of benzene work in the peripheral blood drop and timely replacement of trades, which will help block occupational diseases or aggravate the X-ray group chronic injury longer latency, should strengthen the effective protection
