非肝素化注射器采集动脉血气分析的研究

Study on non-heparinized arterial blood gas analysis syringe acquisition

目的:探讨非肝素化注射器采血对动脉血气分析和电解质测定值的影响。方法:选取20例ICU患者作为研究对象,对同一患者采用两种方法进行动脉血检验,用非肝素化注射器采血的为观察组,用肝素化注射器采血的为对照组,比较两组血气分析和电解质的测定值、护士采血前的准备时间。结果:两组测定的PCO2、Ca2+值差异显著(P<0.05);护士采血前的准备时间差异非常显著(P<0.01)。其余各项测定值,两组之间无显著性差异。结论:选择非肝素化注射器采血避免了肝素钠抗凝剂对血气分析和电解质的影响,且节省了时间、节约了成本、减轻了护士工作量、简化了工作程序,为抢救患者赢得了宝贵的时间。

Objective：To discuss the effect of non -heparinized arterial blood on the arterial blood gas analysis and electrolyte. Methods：To analyse arterial blood of 20 ICU eases on arterial blood gas analysis, electrolyte and the nurse preparation time by heparinized and non - heparinized. Results ： Value of PCO2 ,Ca^2＋ and the nurse preparation time showed siguificanfly difference between two methods（P 〈0.01 ）, and there was no difference about other values. Conclusion：Non- heparinized could avoid the effect of anticoagulants on blood gas analysis and electrolyte, it can also save time, cost, reduce the nurse workload, simplify working procedures and save time for patient salvage.
