目的 探讨婴幼儿血标本采集部位及方法。方法 对 10 1例婴儿和 16 8例幼儿 ,分别从手足背静脉、耳后静脉、股静脉、肘正中静脉、颈外静脉进行采血方法比较。结果 婴儿耳后静脉采血成功率 83.7% ,手足背静脉成功率是 48.3% ;幼儿股静脉采血成功率86 .4% ,肘正中静脉成功率 5 7.4%。差异均有显著性 (P <0 .0 0 5 )。

Objective To investigate the sites and techniques of venous blood sampling in infants and young children. Methods Different sites and techniques of venous blood sampling by puncturing dorsal vein of hand and foot, posterior auricular vein, femoral vein, media cubital vein and external jugular vein were compared in 101 infants and 168 young children.Results Successful rate of venous blood sampling was 83.7% for posterior auricular vein and 48.3% for dorsal vein of hand and foot in infants; 86.4% for femoral vein and 57.4% for media cubital vein in young children, showing significant difference between different sites and techniques (P<0.005). Conclusion Sites and techniques contribute significantly to the successful rate of venous blood sampling in infants and young children.
