试验组

样本量:

128

Group:

Experimental group

Sample size:

干预措施:

试验组(心包后壁开窗术组) 在标准不停跳冠状动脉搭桥术(OPCABG)关胸前,于左侧膈神经后方、左下肺静脉至膈肌之间的心包,做一长约4-5cm的垂直切口,完成心包后壁开窗,使心包腔与左侧胸腔相通,以引流心包积液、降低局部炎症因子浓度。

干预措施代码:

Intervention:

Experimental group (Posterior pericardial window group) Before chest closure during standard off-pump coronary artery bypass grafting (OPCABG), a 4-5 cm vertical incision is made in the pericardium posterior to the left phrenic nerve, between the left inferior pulmonary vein and the diaphragm, to create a posterior pericardial window, allowing communication between the pericardial cavity and the left pleural cavity, thereby draining pericardial effusion and reducing local inflammatory cytokine levels.

Group:

Control group

Sample size:

干预措施:

对照组(标准手术组/假手术对照) 完成标准不停跳冠状动脉搭桥术(OPCABG)后,仅在心包对应位置模拟切开动作,不实际切开心包,其余操作同试验组。

干预措施代码:

Intervention:

Control group (Standard surgery group / Sham control) After standard off-pump coronary artery bypass grafting (OPCABG), a sham incision is simulated at the corresponding pericardial site without actually cutting the pericardium. All other procedures are the same as in the experimental group.

随机方法(请说明由何人用什么方法产生随机序列):

采用区组随机化方法。随机分配序列由不参与研究实施、数据收集和数据分析的独立统计人员,在研究开始前使用计算机(PASS软件)生成。区组大小随机变化(4-10例),以降低研究人员推测随机分配序列的可能性。

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

Block randomization method will be used. The randomization sequence will be generated by an independent statistician who is not involved in study implementation, data collection, or data analysis, using a computer (PASS software) before the start of the study. Block sizes will vary randomly (4-10 participants) to reduce the possibility of researchers predicting the allocation sequence.

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:

单盲。对终点事件评估人员和实验室检测人员设盲,受试者和手术医生因干预措施性质无法设盲。

Blinding:

Single blind. Outcome assessors and laboratory personnel will be blinded to group allocation. Participants and surgeons cannot be blinded due to the nature of the surgical intervention.

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):

暂不共享。研究完成后根据期刊要求及数据共享政策决定。

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

Not to be shared at this stage. Decision will be made after study completion based on journal requirements and data sharing policies.

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:

第一部分:病例记录表(CRF) 采用电子病例报告表(eCRF)进行数据采集。研究者根据原始数据及eCRF填写指南准确、及时、完整、规范地填写eCRF。eCRF内容包括:基线资料(人口学特征、病史、用药史、术前检查)、手术资料(手术时间、桥血管数量、开窗完成情况)、术后资料(房颤发生情况、心电监护记录、炎症因子检测结果、并发症、住院时间、费用)、随访资料(3个月、6个月动态心电图、MACCE事件等)。 第二部分:数据管理 由独立数据管理人员负责数据管理。采用电子数据采集(EDC)系统。数据管理人员对所有访问EDC的用户进行培训,对研究者进行eCRF填写培训。临床监查员(CRA)负责原始数据核对(SDV),核对eCRF数据与源数据的一致性。eCRF填写完成后,系统自动进行逻辑核查并发出质疑。数据管理人员根据数据核查计划(DVP)进行人工核查并发疑。研究者或CRC回答并解决所有质疑后,由主要研究者对数据真实性和完整性进行确认并电子签名。数据库锁定前召开数据审核会议,由申办者、主要研究者、统计师、数据管理人员等共同审核。锁定后的数据库交统计分析人员按统计分析计划(SAP)进行分析。

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

Case Record Form (CRF) Electronic Case Report Forms (eCRF) will be used for data collection. Investigators will complete eCRF accurately, timely, completely, and standardly according to source data and eCRF completion guidelines. eCRF: baseline data (demographics, medical history, medication history, preoperative examinations), surgical data (operation time, number of grafts, completion of pericardial window), postoperative data (AF occurrence, ECG monitoring records, inflammatory cytokine test results, complications, hospital LOS, costs), and follow-up data (3-month and 6-month Holter ECG, MACCE events, etc.). Data Management An independent data manager will be responsible for data management using an Electronic Data Capture (EDC) system. The data manager will train all EDC users and provide eCRF completion training to investigators. Clinical Research Associates (CRAs) will perform Source Data Verification (SDV) to check consistency between eCRF data and source data. After eCRF completion, the system will perform automatic logic checks and generate queries. The data manager will perform manual queries according to the Data Verification Plan (DVP). After all queries are resolved by investigators or CRCs, the principal investigator will confirm data authenticity and completeness with electronic signature. Before database lock, a data review meeting will be held with the sponsor, principal investigator, statistician, and data manager. The locked database will be transferred to statisticians for analysis according to the Statistical Analysis Plan (SAP).
