摘　　要：目的探讨急危重患者动脉血钾与静脉血钾浓度的区别和差异。方法对我院重症监护室收治的急危重合并血钾异常66例患者,分别经动脉留置针采集抗凝动脉血进行血气分析(动脉血组),同时采集静脉血测定血钾浓度(静脉血组),对所有患者及不同血钾水平患者的动静脉血钾进行比较。结果 66例患者静脉组血钾浓度与动脉组血钾浓度进行比较,差异有统计学意义(P<0.05);低钾血症和高钾血症患者动静脉血钾分别进行比较,差异有统计学意义(P<0.05)。结论经动脉留置针采集动脉血作床旁血气分析监测急危重症患者血钾具有方便、快捷、可靠的优势,可作为急危重症患者钾异常的诊治的依据。Objective To expore the difference on artery potassium and intravenous potassium concentration in acute and severe patients. Methods Sixty-six acute and severe patients with potassium anomaly came from our hospital. An- ticoagulant blood of arterial indwelling needle had blood gas analysis（arterial blood group）,venous blood was collected to determine potassium concentration at the same time,all patients and different potassium levels were compared. Re- suits 66 cases of patients with venous potassium concentration and artery group potassium concentrations were com- pared,the difference was statistically significant （P〈0.05）; Hypokalemia and hyperkalemia in patients with arteriove- nous potassium were compared, the difference was statistically significant （P〈0.05）. Conclusion The critical patients with arterial indwelling needle acquisition arterial blood for blood gas analysis by the bed monitoring has the advantages of convenient, quick and reliable, it can be used as the basis for the diagnosis and treatment of potassium abnormalities in critical patients.
