非超声引导下改良塞丁格技术在肿瘤病人PICC置管时的应用

Application of modified seldinger technique on-ultrasound-guided PICC catheterization of cancer patients

目的:探讨非超声引导下无法采用常规穿刺成功置入PICC导管的方法。方法:总结分析122例同期实施PICC置管肿瘤病人因血管条件差,无法实施常规穿刺置管的32例病人,在非超声引导下应用改良赛丁格技术穿刺置管的资料。结果:31例病人置管成功,1例穿刺成功后,因置入导管失败而改为股静脉穿刺,置入到下腔静脉。结论:在非超声引导下采用改良塞丁格技术,可有效解决常规方法不能实现的穿刺,提高了PICC置管成功率,操作简单、方便,作为常规置管的后备方法值得推荐。

Objective：To investigate the special method of non-ultrasound-guided PICC catheterization.Methods：A retrospective analysis of 122 cases of the successful PICC catheterization,among them,non-ultrasound-guided PICC catheterization for 32 patients were implemented by using modified Seldinger technique,which could not be implemented in conventional methods due to poor blood vessels.Results：Successful catheterization for 31 patients,and unsuccessful catheterization for 1 patient,a catheter was inserted into the inferior vena cava through the femoral vein.Conclusion：Catheterization can be effectively implemented by using modified Seldinger technique,which can not be implemented in conventional methods.Modified Seldinger technique improve the success rate of PICC catheterization.This technique is simple,convenient,and is recommended as a back-up of regular catheterization method.
