逆向法定位穿刺点在锁骨下静脉置管术中的对比研究

目的：比较右侧锁骨下静脉置管术中关于定位穿刺点和穿刺方向的两种方法：逆向定位法和锁骨中点下定位法的差异。方法：对笔者所在科2010-2013年进行锁骨下静脉穿刺的102例患者，以个体匹配设计方法分为两组，试验组51例按逆向定位法进行穿刺，对照组51例按锁骨中点下定位法进行穿刺，观察两种定位方法的置管成功率、置管平均耗时以及并发症的差异。结果：成功率试验组为100%，对照组为72.5%，置管平均耗时试验组为（407±59）s，对照组为（577±97）s，并发症累计人次试验组为2例次，对照组为11例次，两组比较差异有统计学意义（P〈0.05）。结论：逆向定位法较常规法有优势。

Comparative Study on the Method of Positioning Puncture Site in the Opposite Direction in Subclavian Vein Cannulation

Objective：To compare the success rate and complications of two different positioning puncture site methods traditional method below the clavicle midpoint and opposite-direction positioning puncture site method in subclavian vein cannulation. Method：Researched 102 cases from 2010 to 2013 in our department were divided into two groups by individual matching method. Experimental group（n=51）was punctured by the method of opposite-direction positioning puncture site,while control group（n=51）was punctured by the method of positioning puncture site under the clavicle midpoint. To compared success rate,operative time and complication rate. Result：The experimental group success rate was 100%,while the control group was 72.5%. The operative time of experimental group was（407±59） seconds,while the control group was（577±97）seconds. Total complication were 2 in the experimental group,while it were 11 in the control group,with a significant difference（P〈0.05）. Conclusion：The opposite direction positioning puncture site method is more advantageous than the conventional method.
