目的通过对平煤某煤矿部分接尘职工的职业健康检查,了解接尘作业职工的健康状况和接尘作业职工胸片及肺功能变化。方法登记受检对象的一般状况,包括姓名、性别、出生年月、婚姻状况、烟酒史、既往史、职业史。检查项目为血压、心电图、高仟伏胸片、肝功、血常规、尿常规、肺功能。胸片诊断按照国家尘肺诊断标准(GBZ 70-2009);肺功能异常标准为FVC<80%,FEV1.0%<70%;肝功异常指标为丙氨酸转移酶>40 U/L;尿常规异常为尿中有白细胞,尿蛋白阳性;高血压诊断根据WHO定义标准,收缩压≥140 mm Hg和(或)舒张压≥90 mm Hg。结果共检查9 310名接尘工人胸部X线异常1 282人(13.8%),肺功能异常405人(4.4%),其他项目异常者在0.7%～4.8%之间。结论①随着煤矿职工接尘工龄的增加,高千伏X线胸片显示肺部异常率增高。②随着接尘工龄增加肺部感染率增加。③随着接尘工龄增加肺功能损害率增高,呼吸功能慢性损害呈进行性加重。
OBJECTIVE To understand the health status of dust-collecting workers and the changes of chest radiographs and lung function of dust-collecting workers through the occupational health examination of dust collectors in some coal mines in Pingdingshan. Methods To register the general status of subjects, including name, sex, date of birth, marital status, tobacco and alcohol history, past history, occupation history. Check items for blood pressure, electrocardiogram, high thousands of volts chest X-ray, liver function, blood, urine, lung function. The chest radiograph was diagnosed according to the national diagnostic criteria for pneumoconiosis (GBZ 70-2009); the standard of lung function was FVC <80%, FEV1.0% <70%; the index of abnormal liver function was alanine aminotransferase> 40 U / Routine abnormalities are white blood cells in the urine, urine protein positive; diagnosis of hypertension according to the WHO definition of standard systolic blood pressure ≥ 140 mm Hg and (or) diastolic blood pressure ≥ 90 mm Hg. Results A total of 1 282 (13.8%) thoracic X-ray abnormalities and 405 (4.4%) pulmonary abnormalities were detected among 9 310 workers exposed to dust. Other abnormalities were between 0.7% and 4.8%. Conclusion ① With the increase of the service life of mine workers, the high kV radiograph shows the abnormal rate of lung increased. ② With the increase of service life of the lung infection rate increased. (3) With the increase of service life of lungs, the damage rate of pulmonary function increased, chronic impairment of respiratory function was progressively aggravated.
