1、超声引导下动静脉穿刺置管超声引导置管(Ultrasound-guided cannulation)被定义为在针穿刺皮肤之前用超声扫描来确定针的存在及其位置,然后进行即时的超声引导的血管穿刺过程。超声协助置管(Ultrasound-assisted cannulation)是指在没有超声即时引导的情况下,用针穿刺之前,用超声扫描来确定目标血管的存在及其位置。超声血管内定位(Ultrasound verification of intravascular placement)是用超声成像描述来确定导引钢丝和导管在目标血管内的正确位置。静脉靠解剖静脉靠解剖动脉靠手摸动脉靠手摸平面内&平面外技术在国内
2、外的应用和准入情况 超声引导下血管穿刺,在临床上已经有十多年的使用经验,根据发表的文章及指南,与基于体表标记的方法相比较,在中心静脉穿刺期间使用超声引导,产生的并发症更少,成功插入套管的尝试次数更少,过程持续时间更短且操作的失败次数更少。因此,美国医疗保健研究与质量局()和英国临床优化研究所()已发布了声明,提倡超声引导下进行静脉插管操作。20022002年年9 9月英国临床技术研究院将超声引导月英国临床技术研究院将超声引导 中心静脉置管作为标准方法在全国推广中心静脉置管作为标准方法在全国推广Alan S.Graham,M.D.et.al.N Engl J Med 2007;356:e21.超

4、ment of Anesthesiology,West China Hospital,Sichuan University,Chengdu,Sichuan 610041,ChinaBackgroudArterial cannulation may be very difficult and time-consuming in severe trauma patients with palpation method due to weak pulse.Complications were relate to multiple attempts to cannulate the artery.Th
5、e purpose of this study was to establish a new artery cannulate method with ultrasound guided,avoiding traditional going through and draw pare ultrasound guided versus traditional palpation placement of arterial lines for time to placement,number of attempts,sites used.MethodsThis was a prospective,
6、randomized study at a tertiary university hospital.Inclusion criteria were severe trauma adult patients requiring arterial catheter insertion for intraoperative monitoring.Patients were randomized to 2 groups,group1 used ultrasound imaging to guiding arterial cannulation,group 2 used traditional pal
7、pation method.U-test,Wilcoxon signed rank sum test were used for statistical analysis.ConclusionsIn this study,a new ultrasound guidence method for artery cannulate was established,ultrasound image of radial artery and artery line was improved by a saline-filled balloon(figure 1,2).Compared with the
8、 palpation method,the success rate of ultrasound guidance for arterial cannulation was higher.Arterial line insertion took less time in ultrasound guidence group.Sever trauma patient could share benifit from ulrasound guidence artery cannulate.ResultsIn our study,we establish a new ultrasound guiden
9、ce method for artery cannulate by using a saline-filled balloon.The image quality of the radial artery and artery line was improved.26 adult patients were enrolled in our study,ultrasound-guided cannulate was success in all patients of Group 1 compared to only 10of 13(76.9%)patients in Group 2;all t
