OBJECTIVE
To determine if heel warming prior to heelstick increases the volume of blood collected compared to no warming.
STUDY DESIGN
Randomized controlled trial involving 100 preterm and term infants requiring capillary blood sampling (CBS), randomized to receive warming (Control) (n=50) or nonwarming (Experimental) (n=50).
RESULTS
This sample of infants showed no benefit of warming the heel prior to CBS. Volume of blood, collection time, crying time, and repeat procedures were not different between groups. More infants in the Control group received squeezing during the procedure compared to the Experimental group.
CONCLUSION
Heel warming prior to CBS may be an unnecessary technique in preterm and term infants that expends nursing time and hospital financial cost.
目的
确定与不进行足跟加热相比，足跟采血前进行足跟加热是否能增加采血量。
研究设计
一项随机对照试验，涉及100名需要进行毛细血管采血（CBS）的早产和足月婴儿，随机分为接受加热组（对照组）（n = 50）和不加热组（试验组）（n = 50）。
结果
该组婴儿显示，CBS前加热足跟并无益处。两组之间的采血量、采血时间、哭闹时间和重复操作次数并无差异。与试验组相比，对照组中有更多婴儿在操作过程中接受了挤压。
结论
对于早产和足月婴儿，CBS前进行足跟加热可能是一项不必要的技术，会耗费护理时间和医院财务成本。
