目的了解职业性慢性二硫化碳(CS2)中毒的临床特征和诊断分级。方法收集53例确诊职业性慢性CS2中毒的资料,采用职业卫生学调查、工作场所职业病危害因素现场检测和职业健康检查进行综合评价。结果53例职业性慢性CS2轻度中毒病例的工作场所2001-2005年二硫化碳(CS2)超过《工作场所有害因素职业接触限值》GBZ2-2002的要求[1];其临床表现以周围神经损伤为主,同时并存中枢神经、视觉系统、心电图等损害或异常表现。结论神经-肌电图改变是诊断职业性慢性CS中毒的重要依据,心电图异常可作为辅助参考。
Objective To understand the clinical features and diagnostic classification of occupational chronic carbon disulfide (CS2) poisoning. Methods Fifty-three cases of chronic occupational chronic CS2 poisoning were collected and evaluated by occupational hygiene survey, field test of workplace occupational hazards and occupational health examination. Results 53 cases of occupational chronic CS2 mild poisoning cases workplace 2001-2005 carbon disulfide (CS2) exceeded the “workplace occupational exposure limits” GBZ2-2002 requirements [1]; its clinical manifestations of peripheral nerve injury as Lord, while coexisting central nervous system, visual system, ECG damage or abnormal performance. Conclusions Nerve-EMG changes are the important basis for diagnosing occupational chronic CS poisoning. Electrocardiogram abnormalities can be used as auxiliary reference.
