Effect of intracavitary electrocardiogram combined with ultrasound-guided PICC catheterization on the accuracy of catheter tip positioning
腔内心电图联合超声引导下PICC置管对导管尖端定位准确性的影响

摘要

目的 探析腔内心电图联合超声引导对PICC置管（外周静脉穿刺中心静脉置管）尖端定位的影响。方法 选取2022年1月-2023年2月期间在我院行PICC置管的60患者纳入对照组，采用超声引导置管；另选2023年3月-2024年3月期间在我院行PICC置管的60例患者作为观察组，予以腔内心电图联合超声引导置管；比较两种置管方法的应用效果。结果 ①两组患者首次穿刺成功率差异较小（P＞0.05）；②观察组置管准确性、患者满意度明显高于对照组（P＜0.05），穿刺耗时、穿刺疼痛指数、并发症总发生率明显低于对照组（P＜0.05）。结论 超声及腔内心电图技术引导下完成PICC置管的准确性更高，更符合临床需求。

Abstract

Objective To explore the effect of endocaval electrocardiogram combined with ultrasonic guidance on the tip location of PICC catheterization (peripheral venipentesis central venous catheterization).
Methods Sixty patients who received PICC catheterization in our hospital from January 2022 to February 2023 were included in the control group, and ultrasound-guided catheterization was performed. Sixty patients who received PICC catheterization in our hospital from March 2023 to March 2024 were selected as the observation group, and intracavitary electrocardiogram combined with ultrasound guided catheterization was given. The application effect of two kinds of catheterization methods was compared.
Results ① There was little difference in the success rate of first puncture between the two groups (P > 0.05). ② The accuracy and satisfaction of patients in the observation group were significantly higher than those in the control group (P < 0.05), and the puncture time, puncture pain index and total complication rate in the observation group were significantly lower than those in the control group (P < 0.05).
Conclusion   The accuracy of PICC catheterization under the guidance of ultrasound and intracavitary electrocardiogram is higher, and it is more in line with clinical needs.
