二维彩超与视锐5超声引导仪在PICC置管术中应用的效果比较

Comparison of the effects of two dimensional Duplex imaging and Site- Rite 5 ultrasound guided instrument during PICC insertion

目的探讨具有二维血流显示功能的彩超与PICC置管专用超声引导仪器—视锐5（SITE，RITE5）在PICC置管中的应用效果。方法将60例需要在超声导引下行PICC置管的患者分为对照组和实验组，分别使用SITE—R1TE5引导仪和具有二维血流显示功能的彩超导引下进行PICC置管，对比2组的血管穿刺成功率、一次置管成功率以及对血管选择的准确率和局部组织损伤率。结果实验组的血管选择准确率略高于对照组，一次血管穿刺准确率、一次置管成功率低于对照组，局部组织损伤率高于对照组，但差异无统计学意义。结论对于暂时不能购置PICC置管专用超声引导仪的医院来讲，可以尝试利用现有的二维彩超仪进行PICC置管，以提高血管条件差的患者PICC置管成功率，使得该项技术得以发展。

Objective To analyze the application effects of two dimensional Duplex imaging and Site- Rite 5 ultrasound guided instrument during PICC insertion. Methods 60 cases underwent color ul- trasound- guided PICC were divided into the control group and the experimental group, they used the Site- Rite 5 ultrasonic guided instrument and two dimensional Duplex imaging for PICC respectively. The success rate of vessel puncture, success rate of one- time insertion, accuracy in vessel selection and the rate of local tissue damage between the two groups were compared. Results The experimental group had a higher success rate in the vessel selection and also with a higher rate of local tissue damage, but success rate of vessel puncture, success rate of one- time insertion were lower than the control group. However, there were no significant differences. Conclusions For the hospitals which can＇t purchase the Site- Rite 5 ultra- sound guidance instrument for PICC, the two dimensional Duplex guidance can be attempted for PICC. It can achieve a higher success rate of insertion, especial in patients with bad condition of the peripheral vessels, so that this technology can be developed rapidly and widely.
