手臂两种不同摆放体位行桡动脉穿刺的效果评价

Effects of two different arm postures on radial artery puncture

目的探讨手臂两种不同摆放体位行桡动脉穿刺的效果。方法按照手术顺序编号,随机将100例患者分为对照组与实验组,每组各50例。对照组患者采用传统方法穿刺置入桡动脉鞘,实验组患者采用改良方法穿刺置入桡动脉鞘。比较两组患者穿刺置入桡动脉鞘所需时间及穿刺成功率情况。结果两组患者桡动脉穿刺成功率比较,P<0.05,差异具有统计学意义,实验组桡动脉穿刺成功率明显优于对照组;两组患者穿刺置入桡动脉鞘所需时间比较,P<0.05,差异具有统计学意义,实验组患者所需时间明显短于对照组。结论采用改良方法实施桡动脉穿刺,其能最大限度暴露桡动脉穿刺点,且保证穿刺部位稳固,从而提高桡动脉穿刺成功率及缩短穿刺时间,值得临床推广应用。

Objective To investigate the effects of two different arm postures on radial artery puncture. Methods We randomly divided 100 patients into control group and experiment group according to the operation sequence, 50 patients in each group. In the control group, the traditional method was used for radial artery puncture and sheath placement, while in the experiment group the modified method was used. Result Compared with the control group, the success rate of radial artery puncture in the experiment group was significantly higher（P〈0.05）, and the time needed was significantly shorter（P〈0.05）. Conclusions The modified arm posture for radial artery puncture and sheath placement is more effective for exposure of the radial artery puncture point and ensure the stability of the puncture site. With this method, we can improve the success rate of radial artery puncture and shorten the puncture time.It is worthy of clinical application.
