Clinical application of prelocalization with ultrasound during internal jugular vein cannulation

Objective To evaluate the clinical value and safety of prelocalization with ultrasound during internal jugular vein cannulation. Methods One hundred patients scheduled for internal jugular vein cannulation from February 2009 to April 2010 were divided into two groups by random digits table with 50 cases in each group. Group U patients were performed by ultrasound-prelocalization method and group T patients were performed by traditional technique. The first successful punctures and the first successful catheterization,puncture times,operation time and complications were recorded. Results Compared with group T, puncture times,operation time and complications were lower in group U [(1.0±0.5) times vs.(2.1±1.4) times;(4.5±1.2) min vs.(6.8±1.6) min;0 vs. 12.0%(6/50)](P＜ 0.01 ). The first successful punctures and the first successful catheterization [96.0% (48/50) and 95.8% (46/48)] in group U were obviously higher than those in group T [ 72.0%(36/50) and 77.8% (28/36)] (P ＜ 0.01 ). Two cases were failed in group T. Conclusion Ultrasound-prelocalization technique is simply and practically method for internal jugular vein cannulation under the stable body position. Key words: Ultrasonography; Postoperative complications; Catheterization; Successful rate
