经中心静脉高浓度补钾治疗低钾血症疗效观察

目的探讨经中心静脉置管微量泵高浓度补钾治疗低钾血症的临床疗效。方法将我院收治的38例低钾血症患者随机分为治疗组和对照组，分别采用不同浓度补钾方法进行治疗。结果治疗组平均血钾浓度恢复至4．0mmol／L的时间为（14．82±4．56）h，恶性窦性心律失常缓解时间为（1．43±0．52）h，24h补钾液体量为（412．63±58．36）mL，均较对照组少（P〈O．05或〈0．01），而24h时血钾浓度平均（4．69±0．35）mmol／L较对照组高（P〈0．05）。结论采用微量泵经中心静脉注入高浓度钾治疗危重患者低钾血症，纠正低血钾速度快，安全有效，值得临床进一步研究推广。

Treatment efficiency observation of high concentration potassium infusion via central vein for hypokalemias

Objective To investigate the clinical effect of high concentration potassium infusion via central vein for hypokalcmias. Methods 38 cases of hypokalemia patients in the hospital as the research object were divided into treatment group and control groups respectively, and treated with different concentrations of potassium liquid. Results In the treatment group, the average time of serum potassium concentration returned to 4.0retool was （14.82 ± 4.56）h, duration of response of malignant sinus arrhythmia was （ 1.43± 0.52）h, total potassium supplement liquid volume in 24h was （412.63 ± 58.36）rnl, which were less than those in the control group （P〈0.05 or 0.01 ）, and serum potassium concentration at 24li was 4.69 ± 0.35retool/L, which was higher than control group （P〈0.05）.Conclusion Injection high concentration potassium by using micro pump in treatment of critically ill patients with hypokalemia via central vein had the advantages of fast correction of hypokalemia, safe and effective, which was worthy of further clinical study.
