1976年l～9月,我院收治广州某厂电镀作业工人4例,男、女各2例;年龄41～47岁;工龄均在16～30年。4例接触铬酸电镀工人中,除有一般神经衰弱症候群、粘膜刺激征及鼻中膈穿孔外,经X线照片发现,4例肺部均出现肺纹理增粗。其中一例出现全副鼻窦炎。血白细胞在正常范围。追问病史,除一例在入院前曾有咳嗽外,余无明显咳嗽史,可排除老年性支气管炎。鉴于患者长期接触史和出现的体征,我们认为,电镀工人对于长期接触有刺激性气体而对肺及副鼻窦是否产生影响很值得进一步注意。对于该4例患者的肺部改变,我们设想是:由于工人在电镀中,大量接触铬酸雾,此种气体具刺激性及穿透性,因而产生对粘膜(咽、鼻)及皮肤明显的刺激征,发生溃疡,坏死,逐步深入,鼻中膈不断受破坏,软骨受破坏形成穿孔。随着气体吸入,铬
In 1976 l ~ 9 months, our hospital admitted to a factory in Guangzhou electroplating workers in 4 cases, male and female in 2 cases; aged 41 to 47 years; length of service in 16 to 30 years. Among the 4 exposed chromic acid plating workers, in addition to the general neurasthenic syndrome, mucosal irritation and nasal septum perforation, the X-ray photographs showed that four cases of pulmonary lung tissue thickening. One case appeared full sinusitis. Blood leukocytes in the normal range. Asked history, in addition to a case of cough before admission, I had no history of cough, can rule out senile bronchitis. Given the long history of exposure and signs, we believe electroplating workers deserve more attention on the long-term exposure of irritating gases to the lungs and paranasal sinuses. For the 4 patients with lung changes, we envisaged that due to the workers' exposure to chromate mist in electroplating, this gas is irritating and penetrating, resulting in significant irritation to mucous membranes (pharynx, nose) and skin Irritation sign, ulcer, necrosis, and gradually deepened, the nasal diaphragm continued to be damaged, perforation of the cartilage destroyed. As the gas is inhaled, chromium
