BD预设型采血器与传统注射器采血在护理流程管理中应用效果的比较研究

Comparative study of application effect of BD preset syringe and regular syringe in arterial blood collection in standardized nursing process

目的在规范的护理流程中对BD预设型采血器与传统注射器动脉采血的方法进行比较，寻找优化的采血方法，规范动脉采血流程。方法制订BD预设型采血器与传统注射器动脉采血的流程，对参加实验的护士进行培训，将需进行动脉血标本采集的500例外科术后患者随机分为血气针组和注射器组各250例。血气针组采用BD预设型采血器采血，注射器组采用传统注射器采血，比较2组血标本凝集情况；从2组中各选取23例进行分步计时，计算各自的工作效率；并对参与动脉采血的护士进行问卷调查，了解护士对2种方法的评价。结果2组患者出现血标本凝集情况注射器组为15例，血气针组2例，2组比较差异有统计学意义；分段计时中2组样本采集准备时间、样本采集时间、样本采集总时间均有显著差异；参与采血的护士对2种采血方法的评价，血气针组亦明显优于注射器组。结论在护理流程管理中采用BD预设型采血器发生血标本凝集的风险小、工作流程效率高、护士操作简便、安全，临床可广泛推广使用。

Objective To explore the best practice and normalization of arterial blood collection by comparing performance of BD preset syringe with regular syringes in arterial blood collection in standardized nursing process. Methods The nurses were trained to use BD preset syringe and regular syringes to collect arterial blood sample. Five hundred subjects were randomly divided into the preset syringe group and the regular syringes group, 250 subjects in each. Agglutination of blood samples was observed. Time spent in every step of collections was recorded for 23 subjects in each group to calculate workflow efficiency. A questionnaire was used for nurses participated in arterial blood collection for their evaluation of both types of syringes. Results The incidence of micro-clot formation in the preset syringe group was 2 cases, lower than 15 cases in the regular syringes group, the preset syringe group also showed higher workflow efficiency as well as safe and easy-to-use characters. The difference between two groups was statistically significant. Conclusions Using BD preset syringe in nursing process management has lower incidence of micro-clot formation, higher workflow efficiency, safe and easy-to-use character. It should be promoted in clinical practice.
