两种不同采血器在新生儿足底采血中的应用比较

目的 通过比较SteriHeel婴幼儿末梢采血器和传统一次性采血针应用于新生儿足底采血的效果,探讨一种较佳的新生儿足底采血器材方法.方法 出生满72h足月正常新生儿200例,随机分为婴幼儿末梢采血器组（A组）和传统一次性采血针（B组）,每组各100例,分别采用不同的采血器进行足底采血.观察并比较2组采血器采血效果及安全性能：一次成功率,总采血时间,采血前、采血期间、采血后1,2,3min时的心率（HR）、平均动脉压（MAP）及脉搏氧饱和度（SpO2）,采血后采血部位伤口深度可控性及足跟红肿发生率等的变化.结果 婴幼儿末梢采血器的一次成功率显著高于传统一次性采血针,前者的采血时间明显短于后者,前者采血前后HR、MAP及SpO2波动时间明显短于后者.前者采血后采血部位伤口深度可控性及足跟红肿发生率与后者差异无统计学意义.结论 婴幼儿末梢采血器应用于新生儿足底采血优于传统一次性采血针.

Objective To compare the peripheral blood collection and disposable lancet to explore a better method of blood collection in neonatal heels. Methods 200 normal neonates at our hospital over 72h were randomly divided into groups of peripheral blood collection （group A） and disposable lancet （group B） of each 100 cases. 2 groups were observed and efficacy and safety were compared the：first success rate,the total blood collection time, changes before, during and after the blood collection 1,2, 3 min when the heart rate, mean arterial pressure and pulse oxygen saturation. After blood collection wound depth controllability and sufficient with red frequency were also observed. Results Rate of first successful peripheral blood collection was significantly higher than disposable lancet. The former blood collection time was significantly shorter than the latter. The former fluctuations of the HR, MAP and SpO2 were significantly shorter than the latter. There was no statistically significant in two groups of wound depth controllability and sufficient with red frequency after blood collection. Conclusion Peripheral blood collection is superior to disposable lancet.
