超声引导下桡动脉穿刺置管在重症患者中的应用

摘要

Objective:To explore the clinicaleffect of radial arterial puncture cannulationunder ultrasonic guidance in patients with critical diseases.Methods:From December 2016 to May 2017,120 patients under critical conditions in Department of Intensive Care Unit,Xiangya Hospital,Central South University,who received arterial cannulation,were randomly divided into 2 groups:a control group (traditional blind puncture method) and an observation group (ultrasound-guided radial arterial cannulation) (60 cases in each group).The success ratio of radial arterial puncture cannulation by one time,total success ratio of radial arterial puncture cannulation,numbers of puncture,the rate of complications and the time of consumption were compared between the 2 groups.Results:There was no statistically significant difference in the total success ratio of radial arterial puncture cannulationin the 2 groups (P＞0.05).The success ratio radial arterial puncture cannulation by one time was significantly greater in the observation group than that in the control group (P＜0.05);the numbers of puncture,the rate of complications and the time of consumption in the observation group were lower than those in the control group,with statistically significant (all P＜0.05).Conclusion:The application of ultrasound-guided radial arterial puncturecannulation can improve the success ratio of radial arterial puncturecannulation by one time,decrease the numbers of puncture,reduce the incidence of complications and save operation time.%目的:探讨超声引导下桡动脉置管在重症患者中的临床效果.方法:以2016年12月至2017年5月人住中南大学湘雅医院重症医学科的120例需要动脉置管的危重患者作为研究对象,并将其随机分为对照组(传统盲穿法桡动脉置管)和观察组(超声引导下桡动脉穿刺置管),各60例.比较两组患者初次置管成功率、总置管成功率、穿刺次数、并发症发生率、操作耗费时间等指标.结果:两组患者总置管成功率比较,差异无统计学意义(P＞0.05);观察组初次置管成功率显著高于对照组(P＜0.05),且穿刺次数、并发症发生率和操作耗费时问均小于对照组,差异均有统计学意义(均P＜0.05).结论:超声引导技术可以提高重症患者桡动脉置管初次置管成功率,减少穿刺次数,降低并发症的发生率,并可节省操作时间.
