研究目的:

本研究是一项由研究者发起的多中心、前瞻性、开放标签、双组平行、盲终点评价的随机对照试验,旨在探讨围手术期不同血压管理策略对接受血肿清除术的高血压性脑出血患者临床结局的影响。 主要目的:比较围手术期采用强化降压策略(收缩压控制在120–140 mmHg)与标准降压策略(收缩压控制在140–180 mmHg)对患者术后90天神经功能结局的影响,以改良Rankin量表评分(Modified Rankin Scale,mRS)4–6分(即重度残疾至死亡)的患者比例为主要评价指标。 次要目的: 1.评估两种血压管理策略对患者术后90天生活依赖率(定义为mRS评分3–5分)的影响。 2.比较两组患者在术后90天健康相关生活质量(采用EQ-5D量表评估)的差异。 3.评估两组患者术后7天内症状性缺血性卒中或无法分型卒中的发生率。 4.观察随机化后90天内急性冠脉综合征的发生情况。 5.系统比较两组在术后再出血、其他血管事件及住院时间等方面的差异,以全面评价强化降压策略的安全性、有效性及临床获益。  

Objectives of Study:

This is an investigator-initiated, multicenter, prospective, open-label, two-parallel-group, randomized controlled trial with blinded endpoint evaluation. The study aims to investigate the effects of different perioperative blood pressure management strategies on clinical outcomes in patients with hypertensive intracerebral hemorrhage undergoing hematoma evacuation. Primary ObjectiveTo compare the effects of intensive perioperative blood pressure reduction (target systolic blood pressure: 120–140 mmHg) versus standard blood pressure control (target systolic blood pressure: 140–180 mmHg) on neurological outcomes at 90 days post-surgery. The primary outcome is the proportion of patients with a modified Rankin Scale (mRS) score of 4–6 (indicating severe disability to death). Secondary Objectives 1. To evaluate the impact of the two blood pressure management strategies on the rate of dependency (defined as mRS score 3–5) at 90 days post-surgery. 2. To compare health-related quality of life at 90 days post-surgery between the two groups, as assessed by the EQ-5D scale. 3. To assess the incidence of symptomatic ischemic stroke or stroke of undetermined type within 7 days post-surgery. 4. To monitor the occurrence of acute coronary syndrome within 90 days after randomization. 5. To systematically compare the two groups regarding postoperative rebleeding, other vascular events, and length of hospital stay, in order to comprehensively evaluate the safety, efficacy, and clinical benefits.

Other: (1) Pregnancy or breastfeeding; (2) Participation in another interventional clinical trial.

随机方法(请说明由何人用什么方法产生随机序列):

采用基于网络的中央随机化系统,由系统根据最小化随机算法生成随机分配序列。在录入研究中心、手术方式、海拔高度等分层信息后,系统以80%的概率将患者分配至能使上述因素在两组间最优平衡的组别。

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

Patients will be assigned using a web-based central randomization system. After eligibility confirmation, investigators enter stratification data (study site, surgical approach, altitude) into the system. A minimization algorithm with an 80% probability is used to assign patients to the treatment group that achieves the best balance of these factors between the two groups.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

开放标签,对评估者设盲

是否共享原始数据:

IPD sharing

否No

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

研究结束后,将提供去标识化的个体参与者数据(IPD),包括研究方案、统计分析计划、数据字典等。数据将通过公共数据平台(网址待定)进行共享,申请获取数据的研究人员需提交研究计划并获得主要研究者批准后方可访问。预计共享时间为主要结果发表后6个月内。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

De-identified individual participant data (IPD), including the study protocol, statistical analysis plan, and data dictionary, will be shared after study completion. Data will be made available via a public repository (URL to be determined). Researchers requesting access must submit a research proposal and obtain approval from the principal investigator. Data will be available within 6 months after publication of the primary results.

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:

本研究采用病例报告表(CRF)收集所有研究数据,并使用电子数据采集系统(EDC)进行数据录入、管理和质控。数据管理包括逻辑核查、范围检查和一致性验证,以确保数据完整、准确。所有数据将存储在加密服务器中,仅授权研究人员可访问。

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

Data will be collected using Case Report Forms (CRFs) and managed via an Electronic Data Capture (EDC) system. Data management includes logical checks, range checks, and consistency verification to ensure data integrity and accuracy. All data will be stored on encrypted servers accessible only to authorized study personnel.
