矽肺是常见职业病之一,本文整理分析哈尔滨水泥厂2800人次矽肺普查资料和胸部X线平片,提高对本病的认识。 资料和方法 哈尔滨水泥厂建厂四十五年,受检人数2800人次,现场作业工人接触水泥原料为矿石、石膏、煤、铁粉等,这些物质中主要含游离二氧化硅(SiO_2),和结合状态的二氧化硅,受检人群中工龄在十年以上一线工人1800人次,工龄在十年以下一线工人500人次,二线工人500人次,二线工人指水泥机械维修工作,房产科工作、水泥化验工作。检查方法为拍胸部前后位X线片,原因肺部背侧活动幅度小,粉尘易滞留,属结节好发处,故背侧靠片易清楚显示病灶,短时间曝光。再结合体格检查,肺功能测定,X线平片需连续三年以上片动态观察。
Silicosis is one of the common occupational diseases. This paper analyzes 2800 people in Harbin Cement Plant silicosis survey data and chest X-ray, improve understanding of the disease. MATERIALS AND METHODS The 45-year-old construction of Harbin Cement Plant and the number of seized persons was 2800. Workers in the field were exposed to cement, ore, gypsum, coal and iron powder. These materials mainly contained free silica (SiO 2) and Combined with the state of silica, the population of the inspected population of more than 10 years in the front-line workers 1,800 people, the length of service less than 10 years 500 front-line workers, second-line workers 500 people, second-line workers refers to the cement machinery maintenance, real estate work, cement test jobs. Check the way to shoot the chest anteroposterior X-ray film, the reasons for the activity of the lungs dorsal amplitude is small, easy to stranded dust, is a nodular good hair, so easy to clearly show the back of the back of the film lesions, short-term exposure. Combined with physical examination, pulmonary function tests, X-ray film for more than three consecutive years of dynamic observation.
