Pulmonary fibrosis states and prevention measures caused by dust exposure of ShenZhen City / 国际检验医学杂志

ABSTRACT

Objective To observe and analyze the occurrence and related factors of pulmonary fibrosis caused by dust exposure in Shenzhen city in 2014 ,and to explore the preventive measures .Methods 64 cases of patients with pneumoconiosis from January 1st ,2014 to December 31st were selected as the study objects ,the factors affecting the development of pneumoconiosis and the re‐lated factors of complications were compared and analyzed ,the preventing measures were discussed .Results the proportion of pneumoconiosis stage Ⅱ and stage Ⅲ and the incidence of complications were increased with the working age of dust‐exposed work ,the differences were statistically significant(P<0 .05) .Compared with patients who used anti‐dust respirator and were trea‐ted in time ,the patients used common respirator and not treated in time had higher proportion of pneumoconiosis stage Ⅱ and stageⅢ and the incidence of complications ,the differences were statistically significant(P<0 .05) .The incidence of complications associ‐ated with pneumoconiosis such as tuberculosis ,pulmonary emphysema ,pulmonary heart disease were higher in patients with more than 20 working years than those with 10- <16 and 16-20 years ,the differences were statistically significant(P<0 .05) .Conclu‐sion Working years of dust‐exposed work ,personal protective measures ,timely treatment are major influence factors for the occur‐rence and development of pneumoconiosis and related complications .Strengthening the engineering and technical measures for re‐ducing dust in dust‐exposed work ,personal protection and health education ,regular physical examination are important means to prevent the occurrence and development of pulmonary fibrosis caused by dust‐exposed work .
