婴幼儿不同部位动脉采血的效果观察

Effect of arterial blood collection from different spots in infants

目的观察桡动脉、肱动脉、股动脉、足背动脉4个部位采血在婴幼儿血气分析标本采集中的应用效果。方法根据不同采血部位将352例婴幼儿分为桡动脉采血组92例、肱动脉采血组94例、股动脉采血组73例、足背动脉采血组53例。比较不同部位动脉穿刺的一次性成功率、并发症发生率。结果桡动脉组穿刺点血肿及误入静脉发生率均较其他3组低(P<0.05);桡动脉组一次性穿刺成功率均高于其他3组(P<0.001)。结论桡动脉是婴幼儿动脉穿刺的首选部位。

ObjectiveTo investigate effects of the arterial blood collection from radial artery,brachial artery,femoral artery and orsalis pedis artery for gas analysis of infants.Methods Three hundred and fifty two infants receiving blood collection were divided into four groups radial artery （n=92）,brachial artery （n=94）,femoral artery （n=73） and dorsal artery （n=53）.Comparisons were done between them in terms of one-time success rate of puncturing and rate of complications from puncturing.Result The radial artery group had lowest rates of hematoma and mistaken puncturing into veins （P〈0.05） and higher rate of one-time successful puncturing （P〈0.001）.Conclusion The radial artery is the first choice for infants undergoing arterial puncturing.
