摘　　要：目的:探讨不同静脉途径注射不同浓度氯化钾治疗重度低钾血症的安全性与疗效。方法:2018年1月-2020年1月收治重度低钾血症患儿97例,随机分为两组。研究组经中心静脉补充6%氯化钾注射液,经微量泵10~15 mL/h注射;对照组经外周静脉注射0.3%氯化钾,经输液泵75~125 mL/h泵入。比较两组治疗效果。结果:研究组在补钾治疗后第6小时及第12小时血钾水平明显高于对照组,研究组血钾浓度达到正常水平所需要时间显著缩短,研究组补钾所需要液体量明显少于对照组,差异均有统计学意义(P<0.05)。结论:在严密监测下经中心静脉微量泵高浓度补钾治疗重度低钾血症,是安全、有效、快速的治疗方法。Objective:To investigate the safety and efficacy of intravenous injection of different concentrations of potassium chloride(kcl)in the treatment of severe hypokalemia.Methods:From January 2018 to January 2020,97 children with severe hypokalemia were selected,they were randomly divided into the two groups.The study group was supplemented with 6%kcl injection through the central vein and injected through the micropump 10~15 mL/h.The control group was injected with 0.3%kcl,via the peripheral vein and pumped through the infusion pump 75~125 mL/h.The therapeutic effects of the two groups were compared.Results:The level of serum potassium in the study group was significantly higher than that in the control group at 6 and 12 hours after potassium supplementation,the time needed for the serum potassium concentration to reach the normal level in the study group was significantly shortened,and the amount of liquid needed to supplement potassium in the study group was significantly less than that in the control group,the differences were statistically significant(P<0.05).Conclusion:High concentration potassium infusion through central venous micropump under close monitoring is a safe,effective and rapid method for the treatment of severe hypokalemia.
