老年患者桡动脉采血方法的改进与效果

Improvements of method for blood collection via arteria radialis among elderly patients

目的探讨老年患者桡动脉穿刺的改进方法。方法188例需要进行桡动脉采血的患者随机分为两组，实验组96例采用改良Allen试验采血，对照组92例采用传统方法采血，评价两组患者穿刺一次成功率和患者疼痛情况。结果实验组患者采血一次成功率高于对照组，疼痛反应低于对照组（P〈0．01）。结论改良Allen试验采血成功率高，患者疼痛程度轻，且操作方法易于掌握，值得临床推广应用。

Objective To explore the improvement method for blood collection via arteria radialis among elderly patientsMethods 188 patients were received radial artery puncture with tradtional way （92 cases） and allen way （96 cases）. First puncture success rate and subjective feeling were compared between two ways. Results First puncture success rate of allen way was higher than that of traditional way （ P 〈 0. 01 ）. Pain of patients in allen way were lower than that of tradional way （ P 〈 0. 01 ）. Conclusions Allen way of radial artery puncture is better in first puncture success rate and subjective feeling of patients, and allen way is easy to master and is worthy generalization in clinical practice.
