【摘要】 目的 比较头皮动脉穿刺和股动脉穿刺两种方法采血进行血气分析检查的穿刺成功率。 方法 新生儿110例。其中50例采用常规方法进行股动脉穿刺，60例采用头皮动脉穿刺采血。 结果 股动脉穿刺组一次穿刺成功率为80%(40/50)，头皮动脉穿刺组一次穿刺成功率96.67%(58/60)，差异有非常显著性(P<0.01)。 结论 小儿头皮动脉穿刺采血穿刺成功率高，是一项符合临床需要的方法。

    【Abstract】 Objective To compare the successful rate of two methods of arterial puncture of cephalic arteria and arteria femoralis for blood gas analysis.Methods One hundred and ten newborns were studied.Fifty newborns had a routine puncture of arteria femoralis，and the other sixty newborns were punctured of cephalic arteria.Results The successful rate for the first time of arterial femoralis puncture is80%.The rate of cephalic arterial puncture is96.67%.The statistical difference is prominent(P<0.01).Conclusion The method of cephalic arterial puncture ......
