动态血流动力学监测在CRRT液体管理中的辅助作用研究

Study on the Auxiliary Role of Dynamic Hemodynamic Monitoring in the Fluid Management of CRRT

摘要: 目的：探讨动态血流动力学监测在CRRT液体管理中的辅助作用，为提高CRRT治疗的精准性与安全性提供科学依据。方法：本研究采用简单随机抽样，选择70例需要接受CRRT液体管理的患者，随机分为观察组与对照组，每组35例。观察组在常规CRRT治疗基础上，增加动态血流动力学监测，实时监测心输出量(CO)、中心静脉压(CVP)等血流动力学指标，动态调整液体管理策略；对照组仅接受常规液体管理。主要观察指标包括心输出量、中心静脉压、血流动力学稳定性、并发症发生率等。结果：观察组在心输出量、中心静脉压、收缩压、舒张压和心率等血流动力学指标上显著优于对照组，且两组并发症发生率无显著差异。动态血流动力学监测能够优化CRRT液体管理，维持血流动力学稳定，减少液体过负荷或不足的风险。结论：动态血流动力学监测在CRRT液体管理中具有显著辅助作用，能够提高液体管理的精准性，改善血流动力学稳定性，降低并发症风险，具有广泛的临床应用前景。

Abstract: Objective: To explore the auxiliary role of dynamic hemodynamic monitoring in the fluid management of CRRT, and to provide scientific basis for improving the accuracy and safety of CRRT treatment. Methods: In this study, 70 patients requiring CRRT liquid management were randomly divided into observation group and control group, with 35 patients in each group. In the observation group, on the basis of routine CRRT treatment, dynamic hemodynamic monitoring was added, and hemodynamic indexes such as cardiac output (CO) and central venous pressure (CVP) were monitored in real time, and fluid management strategies were dynamically adjusted. The control group received only conventional fluid administration. The main outcome measures included cardiac output, central venous pressure, hemodynamic stability and complication rate. Results: The hemodynamic indexes such as cardiac output, central venous pressure, systolic blood pressure, diastolic blood pressure and heart rate in the observation group were significantly better than those in the control group, and the incidence of complications was not significantly different between the two groups. Dynamic hemodynamic monitoring can optimize CRRT fluid management, maintain hemodynamic stability, and reduce the risk of fluid overload or insufficiency. Conclusion: Dynamic hemodynamic monitoring has a significant auxiliary role in the fluid management of CRRT, which can improve the accuracy of fluid management, improve hemodynamic stability, and reduce the risk of complications. It also has a wide clinical application prospect.
