目的研究一起火药爆炸引起砷化物急性中毒治疗过程中尿砷含量变化情况,为防治此类事件引起砷中毒提供依据。方法应用二乙氨基二硫代甲酸银-三乙醇胺分光光度法测定尿砷,并采取切实可行的质量保证措施。结果3名患者尿砷水平均高于我国正常人群尿砷平均值0.13 mg/L,实验室确诊急性砷中毒。结论本地区需要调研制定尿砷正常参考值。凡遇到火药爆炸烧伤者应考虑砷化物急性中毒。
Aim To study the changes of urinary arsenic content in the course of acute arsenic poisoning caused by the explosion of gunpowder, and to provide basis for prevention and control of arsenic poisoning caused by such events. Methods The urinary arsenic was determined by silver diethylamino dithioformate - triethanolamine spectrophotometry and the practical quality assurance measures were taken. Results The urinary arsenic levels of three patients were all higher than the urinary arsenic average of 0.13 mg / L in our normal population. The laboratory diagnosed acute arsenic poisoning. Conclusion In this area, we need to research and formulate urinary arsenic normal reference value. Those who encounter explosive powder burn should consider arsenic acute poisoning.
