目的探讨驱铅试验和神经肌电图等指标在铅中毒诊断中的意义,为职业性慢性铅中毒早期诊断提供科学依据。方法对223例疑似职业性铅中毒病人,按照《职业性慢性铅中毒诊断标准》GBZ37-2002[1]进行诊断分级。结果 223例疑似职业性铅中毒病人经确诊有138例轻度铅中毒,85例中度铅中毒,驱铅试验+神经肌电图,诊断阳性率达100%,单纯血铅诊断阳性率80.3%(179/223)。结论血铅诊断职业性慢性铅中毒的诊断率明显低于诊断性驱铅试验+神经肌电图,为保护职业人群身体健康,建议尽快修订《标准》[1]。
Objective To investigate the significance of indexes such as lead expellation test and neuromuscular electrogram in the diagnosis of lead poisoning and provide a scientific basis for the early diagnosis of occupational chronic lead poisoning. Methods A total of 223 suspected cases of occupational lead poisoning were diagnosed and graded according to GBZ37-2002, a diagnostic criteria for occupational chronic lead poisoning. Results A total of 223 cases of suspected lead poisoning were diagnosed as having mild lead poisoning, 85 cases of moderate lead poisoning, lead expelling test and electromyography. The positive rate of diagnosis was 100%, the positive rate of blood lead was 80.3% (179/223). Conclusion The diagnosis of occupational chronic lead poisoning in blood lead is significantly lower than that of the diagnostic lead drive test + electromyography. To protect the occupational health, it is suggested that the standard be amended as soon as possible [1].
