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。
ObjectiveTo systematically evaluate the efficacy and safety of anatomical landmark method (ALM) versus ultrasound (US)-guided internal jugular vein (IJV) catheterization in pediatric patients. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 10, 2016), CNKI, CBM, WanFang Data and CNKI were searched from inception to October 2016 to collect randomized controlled trials (RCTs) of landmark-guided versus ultrasound-guided IJV catheterization in pediatric patients who underwent elective surgery. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then RevMan 5.3 software was used to perform meta-analysis. ResultsA total of 13 RCTs involving 1 026 pediatric patients were included. The results of meta-analysis showed that, the overall success rate (RR=1.21, 95%CI 1.09 to 1.34, P=0.000 5) and arterial puncture rate (RR=0.19, 95%CI 0.07 to 0.50, P=0.000 7) of US-guided IJV catheterization were both significantly superior to the ALM group. Whereas there was no significant difference between two groups as for the incidence of hematoma formation (RR=0.35, 95%CI 0.09 to 1.31, P=0.12). ConclusionCurrent evidence shows that, for IJV catheterization of pediatric patients, both the effectiveness and safety of ultrasound-guided technique are better than the landmark-guided. Since the quantity and quality of included studies are limited, the conclusion of this study needs more high quality studies to verify.
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.
