Abstract：Objective To explore the method to raise success rate of indwelling needle puncture on great saphenous vein in children.Methods Totally 200 hospitalized children were randomly divided into observation group and control group. All of the children were given indwelling needle puncture on great saphenous vein.In the observation group,the most prominent site of great saphenous vein in the superior medial malleolus or the most protruding site that could be touched was selected as the puncture point,and the puncture angle was not less than 45°.While in the control group,visible site of great saphenous vein in the inferior medial malleolus or the most pitting site that could be touched was selected as the puncture point,and the puncture angle was 1 5 to 30°.The first time,the second and third time to see the blood returning and puncture success rate of 2 groups were compared.Results The first time to see the blood returning in 2 groups had no statistical difference(χ2=0.479,P>0.05),but the cases of the second and third time to see the blood returning and the puncture success in the observation group was significantly more than that in the control group(χ2 =24.381,χ2 =30.645,P<0.01).Conclusion Success rate of indwelling needle puncture of great saphenous vein in children is higher with the most prominent site or the most protruding site that can be touched as the puncture point and the puncture angle was not less than 4 5°.
