摘　　要：目的总结在重症监护病房(ICU)使用微量注射泵经中心静脉高浓度补钾纠正低钾血症的护理体会.方法85例低钾血症患者使用微量注射泵,以5～15 ml/h(6.65～20 mmol/h)的速度经中心静脉输注浓度为10%氯化钾原液,以纠正低钾血症,对补钾过程严密监测和护理.结果采用微量注射泵经中心静脉高浓度补钾,补钾前后血钾浓度比较有显著差异(P＜0.01),血钾浓度的改变与补钾速度呈线性关系,补钾2～8 h血钾回升到正常为83例(占97.6%),补钾后出现高钾血症2例(占2.4%).结论使用微量注射泵经中心静脉高浓度补钾纠正低钾血症的方法在ICU是有效、安全的,但需要严密的临床监测和护理.Objective To summarize nursing experience of micro--injection pump used in high concentration potassium infusion via central vein to correct kaliopenia in ICU. Methods 85 patients with Kaliopenia used micro--injection pump to infuse 10% Potassium chloride via central vein at 5--15ml/h （6.65- 20mmol/h） speed for correcting kaliopenia. Strict monitoring and nursing during 10% Potassium chloride infusion were done. Results There was significant difference in serum potassium concentration before and after using micro--injection pump to infuse 10% Potassium chloride via central vein （P〈 0.01）. There was linear relationship between infusion speed and serum potassium concentration. 83 patients＇ （97.6%） serum potassium concentration increased to normal level after potassium infusion 2-8 hours. 2 patients （2.4%） suffered hyperkalemia. Conclusions It is effective and safe to use micro-- injection pump in high concentration potassium infusion via central vein to correct kaliopenia in ICU, but rigorous clinical monitoring and nursing must be done.
