研究目的:

研究目的 本研究旨在系统性地评估血管活性药物剂量指导的个体化氢化可的松疗程与固定疗程相比,对脓毒症休克患者在短期疗效、安全性及远期预后方面的影响。 主要目的 评估血管活性药物剂量指导的个体化氢化可的松疗程与固定疗程相比对脓毒性休克危重患者28天内的无血管活性药物天数的影响。假设与固定疗程相比,血管活性药物剂量指导的氢化可的松疗程可延长因脓毒性休克入住 ICU 的患者的 28天无血管活性药物天数。 次要目的 评估血管活性药物剂量指导的个体化氢化可的松疗程与固定疗程相比对脓毒性休克患者的恢复、并发症以及治疗相关不良反应发生的影响。  

Objectives of Study:

Research Objective The aim of this study is to systematically evaluate the short-term efficacy, safety, and long-term prognosis of individualized hydrocortisone therapy guided by vasoactive drug dosage compared to fixed therapy in patients with septic shock. main purpose Evaluate the effect of individualized hydrocortisone course guided by vasoactive drug dosage compared to fixed course on the number of days without vasoactive drugs within 28 days in critically ill patients with septic shock. Assuming that compared to a fixed course of treatment, a dose guided course of hydrocortisone with vasoactive drugs can prolong the 28 day period of non vasoactive drug use in patients admitted to the ICU due to septic shock. Secondary purpose Evaluate the impact of individualized hydrocortisone therapy guided by vasoactive drug dosage on the recovery, complications, and treatment-related adverse reactions of septic shock patients compared to fixed therapy.

干预措施:

a.给药方案:氢化可的松200mg/天,持续静脉泵入,固定治疗7天。 b.干预时间:完成7天治疗后,无论血管活性药物使用情况如何,均停止氢化可的松泵入;或患者提前达到休克缓解标准(停用血管活性药物且MAP≥65mmHg持续超过24小时),经临床医师及研究者判断后即可停药。 c. 研究干预的终止与后续治疗:完成7天固定疗程或提前达标停药后,研究干预即告结束。若患者之后再次发生难治性休克,研究者可酌情给予氢化可的松作为常规临床治疗,但不再作为本研究的研究干预。该事件应被记录为“方案偏离”,并在eCRF中详细说明原因及治疗详情。

干预措施代码:

Intervention:

a. Dosage regimen: Hydrocortisone 200mg/day, continuous intravenous infusion, fixed treatment for 7 days. b. Intervention time: After completing 7 days of treatment, regardless of the use of vasoactive drugs, stop pumping hydrocortisone; Or if the patient reaches the shock relief criteria in advance (stopping vasoactive drugs and MAP >= 65mmHg for more than 24 hours), the medication can be stopped after judgment by clinical physicians and researchers. c. Termination and follow-up treatment of research intervention: After completing a 7-day fixed course of treatment or stopping medication in advance to meet the standard, the research intervention ends. If the patient experiences refractory shock again in the future, the researcher may consider giving hydrocortisone as a routine clinical treatment, but it will no longer be used as a research intervention in this study. This event should be recorded as a 'protocol deviation' and the reasons and treatment details should be detailed in eCRF.

随机方法(请说明由何人用什么方法产生随机序列):

本研究将采用中央随机化系统(Central Randomization System),通过基于网络的电子数据采集(EDC)平台实现。该系统将由独立的数据管理中心(DMC)负责运营与维护。随机化将采用置换区组随机化(Permuted Block Randomization) 方法,区组大小为6,以1:1的比例将合格受试者分配至以下两组: a.试验组:血管活性药物剂量指导疗程组; b.对照组:固定氢化可的松疗程组。

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

This study will use a Central Randomization System and implement it through a network-based Electronic Data Collection (EDC) platform. The system will be operated and maintained by an independent Data Management Center (DMC). The randomization will adopt Permuted Block Randomization method, with a block size of 6, and qualified subjects will be allocated to the following two groups in a 1:1 ratio: a. Experimental group: Vasoactive drug dosage guidance course group; b. Control group: Fixed hydrocortisone treatment group.

盲法:

本研究为开放标签设计。由于两组给药疗程差异明显,且需根据血管活性药物剂量实时决策,实施盲法操作及其困难且成本高昂。为最大限度减少偏移,将采取以下措施: a.终点判定的盲化:主要终点(28天内无血管活性药物天数)的计算由不知分组情况的委员会基于电子病历数据完成; b.统计学分析的盲化:所有统计分析将在分组信息被隐藏的情况下进行,直至主要分析完成; 使用客观终点指标:优先选择无血管活性药物天数、死亡率等客观指标。

Blinding:

This study is an open label design. Due to the significant difference in the treatment duration between the two groups and the need for real-time decision-making based on the dosage of vasoactive drugs, blind operation is difficult and costly to implement. To minimize offset to the greatest extent possible, the following measures will be taken: a. Blindization of endpoint determination: The calculation of the primary endpoint (the number of days without vasoactive drugs within 28 days) is completed by a committee based on electronic medical record data without knowledge of grouping; b. Blinding of statistical analysis: All statistical analyses will be conducted with grouping information hidden until the main analysis is completed; Use objective endpoint indicators: prioritize objective indicators such as the number of days without vasoactive drugs and mortality rate.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

为确保多中心数据的一致性和质量,我们建立了全面的质量控制体系。我们制定了统一的电子数据采集系统,并在研究开始前对所有参与中心进行集中培训。我们实施实时数据审核和定期源文件核查,使用中央统计监测来识别异常数据模式。我们还进行定期的现场质量检查和远程监控,使用远程监控技术实时监控数据质量。关键生物标志物检测由中央实验室统一完成,以确保一致性。我们成立了独立的数据管理委员会,定期审核数据质量,并建立了问题反馈机制,以持续改进我们的流程。通过这些措施,我们旨在确保所有中心的数据采集、处理和分析保持高度一致性和可靠性。 所有中心人员将接受培训,解释方案和程序、使用基于网络的随机化系统和电子病例报告表 (eCRF)。中心“启动访视”将通过电话会议、视频会议或在参与中心面对面会议进行。将为研究人员和每个参与中心的临床 ICU 工作人员的教育提供书面和电子材料。

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

To ensure consistency and quality of data across multiple centers, we have established a comprehensive quality control system. We have developed a unified electronic data collection system and conducted centralized training for all participating centers before the start of the research. We implement real-time data auditing and regular source file verification, using central statistical monitoring to identify abnormal data patterns. We also conduct regular on-site quality inspections and remote monitoring, using remote monitoring technology to monitor data quality in real-time. The detection of key biomarkers is uniformly completed by the central laboratory to ensure consistency. We have established an independent data management committee to regularly review data quality and set up a problem feedback mechanism to continuously improve our processes. Through these measures, we aim to ensure high consistency and reliability in data collection, processing, and analysis across all centers. All center personnel will receive training on explaining protocols and procedures, using web-based randomization systems, and electronic case report forms (eCRF). The "initiation visit" of the center will be conducted through telephone conference, video conference, or face-to-face meeting with the participating center. Written and electronic materials will be provided for the education of researchers and clinical ICU staff at each participating center.
