《动脉血气分析临床操作实践标准》采血流程的临床应用研究

The application of standard blood sampling procedure for Clinical Practice Standards for Arterial Blood Gas Analysis

目的:验证《动脉血气分析临床操作实践标准》推荐的采血操作流程在ICU病区应用的实用性和有效性。方法:采用前后历史对照的研究设计,采集某三级甲等医院ICU在《动脉血气分析临床操作实践标准》落实前后护理人员在进行动脉采血过程中的耗时、成功率及成本数据,并进行比较,分析实践标准临床应用的实用性和有效性。结果:落实《动脉血气分析临床操作实践标准》之后,ICU动脉采血一次成功率由90%提高到97%(χ^2=4.031,P=0.045),降低了标本缺陷率(χ^2=5.216,P=0.036),缩短了操作时间(t=3.162,P=0.002),同时也节约了此项操作的成本(t=-2.196,P=0.029)。结论:《动脉血气分析临床操作实践标准》在ICU病区具有一定的实用性和有效性,有利于节约操作成本。

Objective:To explore the practicability and effectiveness of the standard blood sampling procedure that suggested in the Clinical Practice Standards for Arterial Blood Gas Analysis in ICU wards.Methods:A before-and-after historical comparison study design was used,and the cost time,success rate and medical cost of the arterial blood collection before and after the implementation of the standard blood sampling procedure were collected and analyzed.Results:The onetime success rate of puncture for arterial blood collection increased from 90%to 97%(χ^2=4.031,P=0.045),the defect rate of specimens was lowered(χ^2=5.216,P=0.036),the operation time was shortened(t=3.162,P=0.002),and the medical cost for the operation was reduced(t=-2.196,P=0.029)after the implementation of the standard blood sampling procedure in Clinical Practice Standards for Arterial Blood Gas Analysis.Conclusion:The standard blood sampling procedure in Clinical Practice Standards for Arterial Blood Gas Analysis was applicable for arterial blood collection in ICU ward,and it is benefit to save operating costs.
