超声引导与触脉结合在桡动脉穿刺置管中的应用

目的 评估超声引导结合传统触脉定位行桡动脉穿刺置管的临床效果.方法 选取解放军第四一一医院准备择期手术患者60例,ASA Ⅰ或Ⅱ级,年龄32 ～ 87岁,采用数字表法随机分为U、C2组,每组30人.U组:采用传统触脉定位结合超声引导下穿刺置管;C组:采用传统触脉盲探法穿刺置管.记录2组患者定位及准备时间、置管成功时间、一次成功率、总成功率、穿刺次数、失败率及血肿并发症发生率.结果 与传统触脉定位法相比,传统触脉定位结合超声引导法置管成功时间显著缩短(P＜0.01),一次成功率显著提高(P＜0.01),穿刺次数显著减少(P＜0.01).结论 超声引导与触脉结合下行桡动脉穿刺置管,穿刺时间短,一次成功率高,并发症发生率低,安全可靠.

Application of ultrasonography-guided technique combined with pulse-touching in radial artery puncture cannulation

Objective To evaluate the clinical effects of ultrasonography-guided technique combined with pulse-touching in radial artery puncture cannulation.Methods Sixty elective surgical patients with an age from 32 to 87 years old with ASA Ⅰ or Ⅱ grade were equally divided into groups U and C,each consisting of 30 patients.For the patients of group U,radial artery puncture cannulation was performed by using uhrasonography-guided technique combined with conventional pulse-touching positioning,and for the patients of group C,pulse-touching positioning was applied in radial artery puncture cannulation.Various data,such as uLTrasonography positioning and preparation time,cannulation time,first-try success rate,total success rate,the number of punctures,failure rate and rate of hematoma were recorded in the whole process.Results Cannulation time of group U was significantly shortened as compared with that of group C (P ＜ 0.01),and first-try success rate of group U was also significantly increased (P ＜ 0.01),while the number of punctures was significantly reduced(P ＜ 0.01).Conclusion In radial artery puncture cannulation,ultrasonography-guided technique combined with pulse-touching had the features of short puncture time,higher first-try success rate,lower rate of complications,good safety and reliability.
