【摘要】 目的　探讨低血钾症作为三甲基氯化锡 (Trimethyltinchloride ,TMT)中毒早期诊断、早期预防和早期治疗检查指标的价值。方法　对 10起TMT中毒事故调查资料与 56例中毒者的血清钾资料进行综合分析。结果　低血钾症是三甲基氯化锡接触者和中毒者的主要临床表现之一 ,85 7% (48/ 56)的中毒人员有低血钾症表现 ,54 5% (12 0 / 2 2 0 )的TMT接触者血钾降低。多数中毒者的低血钾症可持续 1周以上。结论　血钾可以作为有机锡塑料稳定剂从业人员TMT中毒的早期敏感指标更多还原

【Abstract】 ObjectiveTo study the practical value of h yp okalemia as an early index of diagnosis, therapy and prevention in TMT intoxicat ion. Methods The serum potassium of 56 cases exposed to TMT in 10 poisoning accidents were analyzed. ResultsHypokalemia was found to be the main clinical sign of occupational TMT exposure and intoxicatio n. The serum potassium of 48(85 7%) cases were below 3 5 mmol/L. Hypokalemia w as also found in 120(54 5%) TMT exposers occupationally. Hypokalemia could last more than a week in most of the cases. ConclusionThe availabl e evidence suggested that hypokalemia could be an early sensitive index o f TMT intoxication in workers exposed to organotin plastic stabilizer.更多还原
