  • Ultrasonic Pre-locating Internal Jugular Venous Cannulation in Infants: A Prospective Comparison with the Anatomic Landmarks Method

    ObjectiveTo evaluate the ultrasonic pre locating internal jugular venous cannulation in infants, comparison with the external landmark technique.MethodsSixty two infants scheduled for cardiac surgery were randomized prospectively into two groups. In the anatomic landmarks group( n =30), the patient’s internal jugular vein(IJV) were cannulated by using the traditional method of palpation of carotid pulsation and identification of other anatomic landmarks. In the ultrasonic pre locating group ( n =32), an two dimensional ultrasound scanner image made for locating the puncture site of vessels was used with an operative probe of HP SONOS 4500 system. The number of attempts, success rate, and incidence of complications were compared for two groups.ResultsThe success rate was 100% vs 80% in the ultrasonic pre locating group vs anatomic landmarks group, with a 3.1% vs 26 7% incidence of carotid artery punctures and the number of attempts 1.57±1.04 vs 2.55±1.76. All differences were statistically significant ( P lt;0.05,0.05,0.01). Conclusion Ultrasonographic pre-localization of the IJV is superior to the anatomic landmarks technique in terms of overall success , and decreases incidence of carotid artery puncture.

  • 超声引导下颈内静脉阻断法预防经外周静脉置入中心静脉导管异位颈内静脉的效果观察

    目的 观察超声引导下颈内静脉阻断对预防外周静脉置入中心静脉导管(PICC)时发生颈内静脉异位的效果。 方法 2011年6月-12月将326例PICC置管的患者随机分为观察组和对照组各163例,观察组在送管时运用B型超声引导下阻断颈内静脉;对照组在送管时采用传统的偏头压肩法阻断颈内静脉。置管后通过胸部X线片比较两组患者导管异位率。 结果 观察组发生导管异位2例,对照组发生12例,两组导管异位率差异有统计学意义(χ2=7.537,P=0.006)。 结论 超声引导下颈内静脉阻断法对预防PICC置管时发生导管异位于颈内静脉具有较高的临床意义。

  • B超立体定位可提高颈内静脉穿刺置管成功率

    【摘要】 目的 总结B超引导下对深静脉穿刺置管的方法,减少并发症提高一次性穿刺置管成功率。 方法 2009年8月-2010年1月对99例患者,用超声探头探测颈内静脉,测得直径及皮下距离后,沿静脉纵轴从穿刺点向近心端两点或三点定位,并沿定位标记穿刺进针。 结果 B超定位下一定穿刺成功98例,无气、血胸、颈部血肿及神经损伤等并发症发生。 结论 B超定位能有效提高低年资医师颈内静脉一次性置管成功率,并能相对降低颈内静脉置管并发症。

  • Application of B-Mode Ultrasound Locatization in Catheterization of Internal Jugular Vein (Report of 286 Cases)

    目的 讨论B型超声定位下颈内静脉穿刺置管的经验。方法 回顾我中心2008年11月至2009年4月期间采用B型超声定位行颈内静脉置管的286例患者的临床资料。结果 一次性穿刺成功率为99.3%(284/286),置管成功率为100%(286/286); 穿刺时间50 s~12 min,平均106.8 s; 带管时间5~64 d,平均13 d; 未出现血气胸、皮下血肿等并发症。结论 B型超声定位下颈内静脉穿刺操作简单、方便、安全,适用于各级别医院。在颈短肥胖,被动体位情况下,B型超声定位下置管优势大于传统的盲探法及彩色多普勒超声引导下置管法。

  • 两种消毒法在颈内静脉置管中的效果比较

    目的研究对比安尔碘皮肤消毒剂在颈内静脉置管患者中喷雾消毒和涂擦消毒的效果。 方法2013年5月-6月选取颈内静脉置管患者100例,将其随机分为试验组和对照组各50例。试验组采用先喷雾消毒,再打开颈内静脉穿刺包铺手术巾穿刺;对照组采用先打开颈内静脉穿刺包后涂擦消毒,再铺手术巾穿刺。两组分别在消毒前后进行皮肤采样,并就采样结果进行比较。 结果两组患者消毒后细菌数均为0 cfu/cm2,在穿刺后皮损情况的发生率差异无统计学意义(P>0.05);在消毒液用量、消毒时间、操作时间上,试验组明显优于对照组(P<0.05)。 结论对于需颈内深静脉置管的患者,安尔碘皮肤消毒剂喷雾消毒与涂擦消毒后检测结果均合格,两种消毒方式效果无明显差异,且喷雾消毒所用消毒液量明显比常规涂擦消毒少,操作所用时间短。

  • Safety and Effectiveness of Real-time Two-dimensional Ultrasound Guidance for Internal Jugular Vein Cannulation: A Systematic Review

    ObjectiveTo systematically review the effectiveness and safety of anatomic landmarks positioning method (ALM) and real-time two-dimensional ultrasound (RTUS) guidance in the internal jugular vein cannulation. MethodsWe searched PubMed, EMbase, Web of Knowledge, CBM, WanFang Data and CNKI for randomized controlled trials (RCTs) concerning the effectiveness and safety of ALM and RTUS in the internal jugular vein catheterization up to May 1st, 2014. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assess methodological quality of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 RCTs involving 1 973 cases were included in the metaanalysis. The results of meta-analysis showed that, compared with the ALM method, the RTUS method reduced puncture failure rate (OR=0.08, 95%CI 0.05 to 0.15, P<0.000 01). For safety, compared with the ALM method, the RTUS method was significantly lower in arterial injury rate (peto-OR=0.22, 95%CI 0.14 to 0.37, P<0.000 01), and the incidence of pneumothorax (peto-OR=0.13, 95%CI 0.04 to 0.40, P=0.000 3). ConclusionCompared to the ALM method, the RTUS method has characteristics such as causing fewer traumas, and having higher success rate and fewer complications. Due to limited quantity and quality of the included studies, the above conclusion still needs to be verified by conducting more studies.

  • 超声技术联合经外周静脉置入中心静脉导管支撑导丝头端退出法在导管多次异位颈内静脉复位中的应用

    目的探讨经外周静脉置入中心静脉导管(PICC)置管时导管头端多次异位到颈内静脉时的有效复位方法。 方法收集2014年3月-12月在血管超声引导下行PICC置管时,导管头端异位到颈内静脉3次以上的患者17例,对其首先按常规复位法复位3次,仍不能成功复位,则采用支撑导丝头端退出法,以利用血液流向和重力作用,将异位的导管调整至正常位置。 结果17例患者先采用常规复位法复位3次,均不成功。改用支撑导丝头端退出法进行复位,一次复位成功16例,成功率为94.11%;二次复位成功率达100%。 结论PICC置管联合血管超声,能及时发现导管是否异位颈内静脉,采用常规复位方法3次,均不能成功复位时,采用支撑导丝头端退出法,可有效纠正导管头端异位,提高置管成功率,减少反复送管所致静脉并发症。
