真空采血法对血液标本发生溶血的影响

目的探讨不同静脉采血方法对血液标本溶血现象的影响,并总结真空采血法的护理要点及注意事项。方法将222例抢救室内需要静脉采血的患者随机分成对照组和实验组,每组各111例。对照组采用传统的一次性注射器静脉采血方法进行采血,实验组采用静脉真空采血法,即使用一次性采血针、持针器和真空试管进行采血。结果两组血液标本发生溶血情况比较,差异有统计学意义(P<0.05),其中采用真空采血法进行静脉采血时溶血率较一次性注射器静脉采血低(P<0.05)。结论采用传统的注射器静脉采血法发生溶血的机会高于真空采血法。

Objective To explore the impact of different methods in blood drawing on sample hemolysis, and to summarize the nursing points of vacuum blood drawing. Methods A total of 222 patients who needed blood drawing were randomly divided into the experiment group and the control group, with 111 in each. Conventional single-use syringe was used to draw blood in the control group, while vacuum blood drawing was used in the experiment group, in which single-use blood taking needle, needle carrier and vacuum test tube were used to draw blood. Result Significant difference was found in hemolysis between the two groups, with hemolysis was less seen in the experiment group than in the control group （P 〈 0.05）. Conclusion Conventional blood drawing had more chances of hemolysis than vacuum blood drawing.
