摘要：目的 研究超声辅助下外周静脉中心导管（PICC）在危重症患者静脉通路建立中的临床疗效，重点评估其对相关不良事件的预防效果，为优化危重患者输液方案提供实践依据。方法 纳入2023年1月至2024 年1 月期间在本院重症监护病房接受静脉治疗的60 例危重病例，通过随机数字分配将受试者均分为实验组（30 例）与常规组（30 例）。常规组实施传统无影像辅助的PICC 置入技术，实验组采用超声实时引导的PICC 置入方案。对比分析两组在首次置管成功概率、操作耗时、导管移位比例及不良反应发生频率等方面的差异，并采用统计学方法处理数据。结果 实验组首次置管成功比例显著优于常规组，具有统计学差异（P=0.011）；实验组操作时长较常规组明显缩短（P<0.001）；导管位置异常发生率实验组更低，差异具有统计学意义。实验组各类并发症出现概率均低于常规组，差异均达到统计学显著水平（P<0.05）。结论 对危重症患者实施超声引导的PICC置管技术，能够显著提升首次置管效率，减少操作时间，有效控制导管位置异常，同时明显降低置管后各时期并发症风险，在重症监护领域具有重要应用前景，建议临床推广。

Abstract：Objective This study investigates the clinical efficacy of ultrasound-guided peripheral indwelling catheter (PICC)placement in critically ill patients, with a focus on evaluating its preventive effects against adverse events to optimize intravenoustherapy regimens. Methods A total of 60 critically ill patients receiving intravenous treatment in the ICU from January2023 to January 2024 were enrolled. Participants were randomly assigned to an experimental group (30 cases) and a conventionalgroup (30 cases) through digital allocation. The conventional group underwent traditional imaging-assisted PICC placementtechniques, while the experimental group utilized ultrasound-guided real-time placement protocols. Comparative analysis wasconducted on first-time catheterization success rates, procedure duration, catheter displacement rates, and adverse reaction frequencies,with statistical analysis performed.Results The experimental group demonstrated significantly higher first-time catheterizationsuccess rates (P=0.011) compared to the conventional group. The experimental group also showed significantly shorterprocedure durations (P<0.001). The incidence of catheter malposition was notably lower in the experimental group, with statisticallysignificant differences. All complication rates in the experimental group were significantly lower than those in the con ventional group (P<0.05). Conclusion Ultrasound-guided PICC placement technology for critically ill patients can significantlyimprove first-time catheterization efficiency, reduce procedure time, effectively control catheter malposition, and substantiallylower post-catheterization complication risks. This approach holds important clinical application potential in intensive care andis recommended for clinical promotion.
