A study on the application effect of bedside ultrasound-assisted CRRT in regulating fluid balance in critically ill patients
床旁B超辅助CRRT调控重症患者液体出入量的应用效果研究

摘要

目的 探讨床旁B超辅助连续性肾脏替代治疗调控重症患者液体出入量的应用效果。选择2024年11月-2025年11月期间我院重症医学科接受CRRT治疗的42例。方法 重症患者为研究对象，按照随机分组的方式分为对照组和实验组，对照组采用常规液体管理方案，实验组在常规基础上联合床旁B超监测下腔静脉相关指标指导液体出入量调控。探讨不同管理方式对患者的影响。结果 实验组液体出入量达标率高于对照组（P＜0.05）。实验组患者治疗72h后的Scr、BUN等肾功能指标均优于对照组（P＜0.05）。结论 床旁B超辅助连续性肾脏替代治疗调控重症患者液体出入量可有效提高液体出入量达标率，改善患者肾功能指标，值得临床推广应用。

Abstract

Objective To explore the application effect of bedside ultrasound-assisted continuous renal replacement therapy in regulating fluid balance in critically ill patients. A total of 42 patients receiving CRRT in the intensive care unit of our hospital from November 2024 to November 2025 were selected.
Methods Critically ill patients were randomly divided into a control group and an experimental group. The control group received conventional fluid management, while the experimental group additionally utilized bedside ultrasound to monitor inferior vena cava-related indicators for guiding fluid balance regulation. The effects of different management approaches were analyzed.
Results The experimental group showed a higher fluid balance achievement rate than the control group (P < 0.05). After 72 hours of treatment, the experimental group exhibited superior renal function indicators such as Scr and BUN compared to the control group (P < 0.05).
Conclusion   Bedside ultrasound-assisted continuous renal replacement therapy effectively improves fluid balance achievement rates and enhances renal function indicators in critically ill patients, making it worthy of clinical promotion and application.
