晚发性尘肺,是指有一段时间接触粉尘的工人,在脱尘若干年之后,经胸部X线照片而新发现的尘肺。目前,有些企业忽视了对脱离粉尘作业工人的定期健康监护,致使他们患了尘肺得不到及时诊断,而首次确诊往往即为二、三期尘肺。这样,既延误了治疗的良机,又增加了患者的痛苦。因此,厂矿企业不容忽视晚发性尘肺的防治工作。 Delayed pneumoconiosis is defined as the pneumoconiosis newly discovered by chest radiographs of workers who have been exposed to dust for some time after they have been dehumidified for some years. At present, some enterprises ignore the regular health guardianship of workers who are separated from dust and cause them to get pneumoconiosis without timely diagnosis. However, the first diagnosis is usually the second or third pneumoconiosis. In this way, not only delayed the opportunity for treatment, but also increased the patient’s pain. Therefore, factories and mines can not ignore the prevention and treatment of late-onset pneumoconiosis.
