Optimization of PICC catheter tip localization methods and nursing practices
PICC导管尖端定位方法的优化与护理实践

摘要

目的 优化PICC导管尖端定位流程，提升定位准确率与护理质量，降低相关并发症风险。方法 选取2025年1月-3月行PICC置管的100例患者，随机分对照组与实验组各50例。对照组采用传统“体外测量+胸部X线”定位，实验组实施“超声引导置管+床旁即时超声定位+动态随访”优化方案，对比两组定位准确率、定位耗时、并发症发生率。结果 实验组定位准确率98.00%高于对照组82.00%（χ²=6.061，P=0.014）；定位耗时（18.5±3.2）min短于对照组（35.2±4.8）min（t=20.395，P＜0.001）；并发症发生率4.00%低于对照组18.00%（χ²=5.005，P=0.025）。结论 优化后的定位方案可显著提升PICC导管尖端定位效能，保障置管安全，为临床护理提供可靠依据。

Abstract

Objective To optimize the localization process of PICC catheters, improve localization accuracy and nursing quality, and reduce related complication risks.
Methods A total of 100 patients who underwent PICC catheter placement from January to March 2025 were randomly divided into a control group (50 cases) and an experimental group (50 cases). The control group used traditional “external measurement+chest X-ray” localization, while the experimental group implemented an optimized protocol combining “ultrasound-guided catheter placement+bedside real-time ultrasound localization+dynamic follow-up.” The accuracy rate, localization time, and complication incidence were compared between the two groups.
Results The experimental group achieved a localization accuracy rate of 98.00% (χ²=6.061, P=0.014), significantly higher than the control group’s 82.00%. The localization time in the experimental group (18.5±3.2) minutes was shorter than that in the control group (35.2±4.8) minutes (t=20.395, P<0.001). The complication incidence rate in the experimental group (4.00%) was lower than that in the control group (18.00%) (χ²=5.005, P=0.025).
Conclusion   The optimized localization protocol significantly enhances the efficiency of PICC catheter tip localization, ensures catheter placement safety, and provides reliable clinical nursing guidance.
