新生儿两种采血方法的观察

Comparative study of effects of two puncture ways to get blood sampling in neonates

目的:探讨适合新生儿血液标本采集的最佳途径。方法:224例新生儿随机分为对照组和观察组各112例,对照组采用股静脉取血法,观察组采用手背静脉滴血法,对两组静脉穿刺成功率、不良事件发生率进行比较。结果:两组静脉一次穿刺成功率、不良事件发生率比较,差异均有统计学意义(P<0.01,P<0.05)。结论:采用手背静脉滴血法采集血标本,静脉穿刺成功率高、不良事件发生几率小,在采集小剂量血标本时优于股静脉取血法。

Objective： To explore the appropriate method of blood sampling in neonates. Methods： 224 newborns were randomly divided into control group and observation group, with each group having 112 neonates. In control group, blood samples were drawn via femoral vein, while in observation group, blood samples were obtained by collecting blood drops from a needle via hand dorsum vein. The successful rate of vein puncture and the incidence of adverse event of two groups were compared. Results： There was significant difference in successful rate of vein puncture and incidence of adverse event （ P 〈 0.01, P 〈 0.05 ）. Conclusion： Blood sampling by collecting blood drops via hand dorsum vein has signifieantly higher successful rote of vein puncture and apparently lower incidence of adverse event, It provides a better way of collecting blood sample when limited amount of blood sample is needed.
