研究目的:

1.主要目的:1)评价不同抗凝方式对体外循环管路寿命的影响(定义为从CRRT治疗开始,到因体外循环回路(包含滤器、管路、静脉壶)发生凝血而被迫终止治疗并更换全套设备所持续的时间(单位:小时) 2.次要目的:1)评价不同抗凝方式在CRRT中的安全性 2)评价不同抗凝方式对CRRT患者预后的影响:ICU住院时长,总住院时长,ICU死亡率,住院期间死亡率,28天死亡率,90天死亡率等的影响 3)评价不同抗凝方式对CRRT患者体内炎症水平(PCT,CRP,IL-6)的影响  

Objectives of Study:

Primary Objective To compare the extracorporeal circuit life-span of RCA, NM and RCA+NM in critically ill patients with AKI undergoing CRRT. Extracorporeal Circuit lifespan is defined as the duration (hours) from the initiation of CRRT to the time when therapy is mandatorily discontinued and the entire extracorporeal circuit set (including the filter, tubing, and venous chamber/drip chamber) is replaced due to circuit clotting. Secondary Objective 1 To assess the safety profiles of the different anticoagulation modalities during CRRT. Secondary Objective 2 To evaluate the effects of different anticoagulation modalities on clinical outcomes in CRRT patients. Secondary Objective 3 To examine the effects of different anticoagulation modalities on systemic inflammatory levels in CRRT patients.

随机方法(请说明由何人用什么方法产生随机序列):

由不参与患者招募与治疗的独立研究人员,使用计算机生成的随机数字序列,将患者随机分入局部枸橼酸抗凝组,萘莫司他抗凝组或局部枸橼酸+萘莫司他抗凝组

Randomization Procedure (please state who generates the random number sequence and by what method):

Independent researchers not involved in patient recruitment or treatment will use a computer-generated random number sequence to allocate patients to one of three groups: the regional citrate anticoagulation (RCA) group, the nafamostat mesylate (NM) group, or the combined RCA+NM group.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

本研究采用单盲设计并对结局评估者设盲:患者不知晓所接受的具体抗凝方案,而负责执行的临床医师知晓分组以确保治疗安全;同时,判定主要终点(体外循环管路寿命)及分析实验室数据的研究人员均对分组信息保持盲态,以最大限度地减少评估偏倚。

Blinding:

This study employs a single-blind design with blinding of outcome assessors: patients will be unaware of the specific anticoagulation regimen they receive, while the treating clinicians performing the procedure will be unblinded to ensure treatment safety. Concurrently, the researchers responsible for adjudicating the primary endpoint (filter lifespan) and analyzing laboratory data will remain blinded to group assignment to minimize assessment bias.

研究数据将使用根据方案设计的标准化病例报告表进行采集,并通过基于互联网的电子数据采集系统进行统一管理和存储。本研究计划使用 ResMan临床试验公共管理平台作为EDC系统。所有数据将经过双重录入与逻辑核查,并由专职数据管理员负责质量控制与安全维护,以确保数据的准确性、完整性与保密性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Study data will be collected using standardized Case Report Forms designed according to the protocol and will be uniformly managed and stored through a web-based Electronic Data Capture (EDC) system. This study plans to use the ResMan Clinical Trial Public Management Platform as the EDC system. All data will undergo double data entry and logic checks, with a dedicated data manager responsible for quality control and security maintenance to ensure data accuracy, completeness, and confidentiality.
