Objectives of Study: |
Primary Objective: To investigate that perioperative use of remimazolam for anesthesia induction and maintenance is non-inferior to propofol in terms of the incidence of postoperative delirium. Secondary Objective: To observe the effects of remimazolam on perioperative hemodynamics, expression of inflammatory factors and neurocognitive disorder-related proteins, so as to accumulate clinical experience and provide theoretical basis for optimizing perioperative management and reducing postoperative complications in elderly patients undergoing laparoscopic colon cancer surgery. |

随机方法(请说明由何人用什么方法产生随机序列): |
研究开始前,由一名独立的不参与后续试验的研究助理人员使用在线随机数字工具生成随机序列。具体条件是:分配比例为1:1,可变区组大小为2和4,序列长度为144。将入组患者随机分为瑞马唑仑组(n = 73)和丙泊酚对照组(n = 73)。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Prior to the start of the study, an independent research assistant who was not involved in the subsequent trial generated the randomization sequence using an online random number generator. The specific conditions were: an allocation ratio of 1:1, variable block sizes of 2 and 4, and a sequence length of 144. Eligible patients were randomly assigned to the remimazolam group (n = 73) and the propofol control group (n = 73). |

|
盲法: |
由于瑞马唑仑和丙泊酚在外观上的显著差别,且负责麻醉的主治医师在术中需要根据临床情况来调整麻醉深度和试验药物的用量,因此对其不设盲。术中的相关数据均由对分组不知情的独立研究人员采集。所有患者、胃肠外科医师、术后随访人员、围术期护理人员等在整个研究过程中均对分组不知情。当发生严重不良反应时可紧急揭盲。 |
|
Blinding: |
Blinding of the attending anesthesiologists was not feasible due to the significant visual differences between remimazolam and propofol, and the need for the anesthesiologists to titrate the depth of anesthesia and the dosage of the study drugs according to clinical conditions during surgery. All intraoperative data were collected by independent researchers who were blinded to group allocation. All patients, gastrointestinal surgeons, postoperative follow-up personnel, and perioperative nursing staff remained blinded to group assignment throughout the entire study period. Emergency unblinding may be performed in the event of a serious adverse event. |

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: |
术后谵妄作为主要结局指标,采用 3D-CAM 量表于术后第 1、2、3 天每日上午 8:00-10:00 和下午 16:00-18:00 进行评估,由对分组情况不知情且经过统一培训的术后随访人员完成,若患者出现意识状态急剧变化则随时追加评估,评估结果即时记录于病例报告表 (CRF);次要结局指标包括围术期血流动力学指标(入手术室时、麻醉诱导后、气管插管后、手术开始后 30 分钟、手术结束前5-10min的平均动脉压及心率)、术前及术后炎症指标和神经认知障碍相关蛋白、术后 30 天内心肺及肝肾并发症发生情况、PACU 机械通气时间、首次排气时间及住院时长,均由对分组不知情的研究人员采集或从医院信息系统提取核实;所有 CRF 表由两名独立数据录入员进行双录入核查,不一致之处与原始病历核对确认,数据录入完成后进行逻辑核查和清理,锁定数据库后方可进行统计分析,研究数据加密存储于研究中心专用服务器,仅授权研究人员可访问,严格保护受试者隐私。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Postoperative delirium, as the primary outcome measure, will be assessed using the 3-Minute Diagnostic Interview for CAM-defined Delirium (3D-CAM) scale on postoperative days 1, 2, and 3, at 8:00-10:00 AM and 4:00-6:00 PM daily. Assessments will be performed by uniformly trained postoperative follow-up personnel who are blinded to group allocation. Additional assessments will be conducted immediately if the patient experiences acute changes in consciousness, and all results will be recorded in the Case Report Form (CRF) without delay. Secondary outcome measures include perioperative hemodynamic parameters (mean arterial pressure and heart rate at the time of entering the operating room, after anesthesia induction, after tracheal intubation, 30 minutes after the start of surgery, and 5-10 minutes before the end of surgery), preoperative and postoperative inflammatory markers and neurocognitive disorder-related proteins, incidence of cardiopulmonary, hepatic and renal complications within 30 days after surgery, duration of mechanical ventilation in the Post-Anesthesia Care Unit (PACU), time to first flatus, and length of hospital stay. All these data will be collected by study personnel blinded to group assignment or extracted and verified from the hospital information system. All CRFs will undergo double data entry and verification by two independent data entry clerks, and any discrepancies will be resolved by cross-checking with the original medical records. After data entry is completed, logical checks and data cleaning will be performed, and statistical analysis will only be conducted after database lock. Study data will be encrypted and stored on a dedicated server of the research center, accessible only to authorized research personnel, to strictly protect subjects' privacy. |
