目的比较两种超声引导方法在经外周静脉置入中心静脉导管(PICC)中的应用。方法选取行PICC置管术的肿瘤患者80例,随机分为观察组与对照组,每组40例。观察组采用超声引导+超声直视下阻断颈内静脉行PICC置管,对照组常规行超声引导下PICC置管。比较两组患者的穿刺一次成功率、穿刺时间、导管异位率及患者的舒适度。结果与对照组比较,观察组一次穿刺成功率高,穿刺时间短,导管异位发生率低,患者舒适度好(P<0.05)。结论超声引导+超声直视下阻断颈内静脉行PICC置管,可提高穿刺成功率,临床效果好。
Objective To compare the application of two methods of ultrasound guidance in central venous catheterization (PICC) via peripheral vein. Methods Eighty patients with PICC who underwent PICC were randomly divided into observation group and control group, 40 cases in each group. In the observation group, the PICC catheter was blocked by ultrasound guidance and ultrasound under direct vision, while the PICC catheter was guided by ultrasound in the control group. The puncture success rate, puncture time, catheterization rate and patient comfort were compared between the two groups. Results Compared with the control group, the puncture success rate, puncture time and catheter ectopic rate in the observation group were significantly lower than those in the control group (P <0.05). Conclusion Ultrasound-guided ultrasound with PICC blocked the internal jugular vein can improve the success rate of puncture, and clinical effect is good.
