低浓度肝素液3种给药方式在动脉置管维护中的效果比较

Low concentration of heparin three dosing way in arterial catheter maintenance effect comparison

目的：探讨低浓度肝素液的不同给药方式在维护动脉置管，保持置管管路通畅的效果。方法：选择150例外周动脉置管的患者为研究对象，用随机数字表法将患者分为A、B、C组。A组为实验组，采用自控电子输注泵输注；B组为对照1组，采用微泵泵入；C组为对照2组，采用间断推注注入。比较3组给药方式在动脉置管维护中管路通畅的情况、凝血功能的变化情况及护理工作量的情况。结果：A组、B组、C组在动脉管路通畅、凝血功能2个方面的差异不明显，而A组、B组护理人员工作量明显减轻，且A组减轻更为明显。结论：3种不同的给药方式对维持动脉管路的通畅效果相近，但A组和B组能明显减轻护理工作量，且A组优于B组。

Objective：To study the different dosage of low concentration of heparin in the maintenance of arterial catheter, keep the place we can smooth effect. Methods：select 150 exception peripheral arterial catheter patients as the research object, using micro pump pumping;C to control 2 group, adopting the continuous push note injection. Compared three groups dosing method of pipe flow in arterial catheter maintenance,changes of blood coagulation function and nursing workload. Results：in group A, and nursing staff in group A, group B significantly reduce workload, and ease of group A is more apparent. Conclusion： three different delivery way to maintaining the smooth effect of arterial line close, and in group A than group B.
