静脉留置针置管改进技术对穿刺成功率的影响

Impact of modified puncture method of IV catheter system with "Y" adapter on the success rate

目的探讨静脉留置针的不同穿刺方法对静脉留置针穿刺成功率的影响。方法将行静脉留置针穿刺的160例肺癌患者随机分为观察组80例和对照组80例。对照组按传统的静脉留置针的方法穿刺并固定,观察组采用改良的静脉留置针的方法穿刺并用贴膜固定,比较两组穿刺的成功率。结果观察组的静脉留置针的一次性穿刺成功率为97.5%,对照组为77.5%,差异有统计学意义(P<0.05),且渗液渗血、发生静脉炎等并发症发生情况与对照组比较,差异无统计学意义(P>0.05)。结论采用改良的静脉留置针的穿刺方法可明显提高静脉留置针的穿刺成功率,节约护理操作时间,对穿刺局部并发症的发生无影响。

Objective To explore the impact of different puncture methods on the success rate of inserted intravenous injector. Meth- ods A total of 160 cases were divided into two groups at random from January 2012 to June 2012. The control（ n = 80） received traditional vein puncture and the experiment （ n = 80） was performed with modified method of vein puncture, then the success rate of the two groups was compared. Results The success rate of the experiment group was significantly higher than that of the control;the success rate of the experi- ment and the control was 97.5% and 77.5% , respectively. There was no significant difference in puncture complications （bleeding, phlebi- tis）. Conclusion The modified method can significantly improve the puncture success rate of inserted intravenous injector and it had no effect on the complications of puncture position. Besides, it can reduce the psychosomatic and economic pressure of the patients and thus is worth clinical application.
