静脉留置针两种不同送管方法的对照研究

Comparative study on the two different placements of venous indwelling catheter

目的:探讨静脉留置针的最佳送管方法,以提高一次送管成功率,减少留置并发症。方法:随机将400例应用留置针患者分为两组,观察组200例,操作时左手固定针芯,以针芯为支撑,右手将外套管全部送入静脉内;对照组200例,操作时将针芯的针尖部退入外套管内,借助针芯将外套管与针芯一起送入静脉内。结果:观察组与对照组在一次送管成功率及留置并发症方面比较,有显著性差异(P<0.01)。结论:观察组的送管方法可明显提高一次性送管成功率,减少留置并发症。

Objective: To explore the best placement of catheter so as to increase the success rate of one-time placement and reduce complications. Methods: 400 patients were randomly divide into observation group (n=200) and control group (n=200). In the observation group, the performance was taken as fixing stylet by left hand and sent cannula into vein by right hand completely taking the stylet as supporter, and in the control group, withdrawing the pinpoint to the inside of external cannula and sent the external cannula with stylet into vein together. Results: The significant difference was shown in the comparison of success rate of one-time placement between the two groups (P<0.01). Conclusion: The performance taken in the observation group can apparently increase the success rate of one-time placement and reduce complications.
