目的 探讨经外周静脉微泵泵入高浓度钾治疗重度低钾血症的临床应用。方法　对62例低钾血症患者随机分成两 组，其中，实验组31例，予以肘正中静脉或贵要静脉、头静脉置管后，在床边心电监护、血钾监测指导下利用微泵 泵入含钾液补钾；同样予以对照组31例，经常规外周静脉补钾。结果 不同时段相同时间实验组患者血钾、肌力、 心电图好转时间明显短于对照组，差异均有统计学意义(P<0.05)。结论 在床边心电监护及血钾监测指导下，通过 肘正中静脉或贵要静脉、头静脉置管后微泵补钾是安全有效的。

Objective To study the clinical effects of perpheral vein by microinfusion pump on severe hypokalemia. Methods The hypokalemia patients were randomly divided into groups.The study group were used microinfusion pump to supplement potassium through median cubital vein and cephalic vein.The contrl group were used intavenous drip to supplement potassium through conventional perpheral vein. Results The serum potassium of the patients in the two groups were significant difference(P<0.05). Conclusion Treatment of severe hypokalemia used vein microinfusion pump through the median cubital vein and cephalic vein may be better than the effects of potassium through peripheral venous.
