食指固定定位法在桡动脉采血中的应用

Application of the index finger positioning method in radial artery blood

目的探讨食指固定定位法在桡动脉采血中的应用效果。方法将250例患者随机分为观察组130例和对照组120例,对照组使用传统的食指和中指固定定位法采集桡动脉血,观察组使用食指固定定位法采集桡动脉血,比较两组采血一次穿刺成功率。结果两组桡动脉采血一次穿刺成功率比较,差异有统计学意义(P<0.05)。结论采用食指固定定位法采集桡动脉血可以提高一次穿刺成功率。

Objective Discussed the effection of forefinger fixed location in radial artery blood collection. Meth- ods The 250 patients were randomly divided into observation group of 130 patients and a control group of 120 pa- tients. The control group using traditional location with forefinger and middle finger collected radial artery blood, and the abservation group using forefinger fixed location. Then compared the first puncture succse rate between the observation group and the control group. Results It is statisically singnificant compared between the first punc- ture success rate of blood collected in radial artery in obsevation group and control group. Conclusion It may improve the first puncture success rate that using forefinger fixed location in radial artery blood collection.
