不同类型外周血标本电解质检测结果比较

Comparison of electrolyte levels between different peripheral blood samples

目的探讨动脉全血与动脉血浆、静脉血浆钾、钠、氯离子检测结果的差异。方法选择住院患者100例,采集肝素锂抗凝动脉全血标本及静脉血浆标本,采用罗氏公司AVL 9180型电解质分析仪检测动脉全血、动脉血浆、静脉血浆标本钾、钠、氯离子水平。结果动脉全血与动脉血浆钠、氯离子水平比较差异有统计学意义(P<0.05),钾离子水平比较差异无统计学意义(P>0.05)。动脉全血与静脉血浆钠、氯离子水平比较差异有统计学意义(P<0.05),动脉全血与静脉血浆钾离子水平比较差异无统计学意义(P>0.05)。结论动脉全血与动脉血浆、静脉血浆钠、氯离子浓度存在差异,而动脉全血与动脉血浆、静脉血浆钾离子浓度可互为参照。

Objective To study the difference of electrolyte levels between different peripheral blood samples .Methods A total of 100 patients were enrolled and collected for artery whole blood samples and vein plasma samples .Potassium ,sodium and chloride levels of artery whole blood ,artery plasma and vein plasma were tested by using ROCHE AVL 9180 analyzer .Results Sodium and chloride levels in artery whole blood and artery plasma were statistically different （P〈0 .05） ,but the difference of potassium levels were not significant （P〉0 .05） .Sodium and chloride levels in artery whole blood and vein plasma were statistically different （P〈0 .05） ,but the difference of potassium levels were not significant （P〉0 .05） .Conclusion Sodium and chloride concentration of ar‐terial whole blood and arterial plasma ,vein plasma could be different ,but the concentration of potassium could be reference for each other .
