随机方法(请说明由何人用什么方法产生随机序列): |

Randomization Procedure (please state who generates the random number sequence and by what method): |
Non-participating researchers generated random numbers by computer, and the enrolled patients were randomly assigned at a ratio of 1:1:1 to the control group, the dexmedetomidine group, or the permissive hypercapnia combined with dexmedetomidine group. |

|
盲法: |
本研究受试者、术后神经功能评估者、数据统计分析者对患者分组信息均不知情,实现受试者-评估者双盲。受试者盲法指所有患者术前仅被告知将接受标准麻醉+围术期脑保护相关治疗,不告知具体分组及干预措施。结局评估者盲法是指术后神经认知、脑功能相关指标等由不参与麻醉实施、不知分组方案的专职评估医师完成,评估者全程不接触麻醉记录与分组信息。 |
|
Blinding: |
The study subjects, postoperative neurological function evaluators, and data statisticians were all unaware of the patient grouping information, achieving a subject-evaluator double-blind design. Subject blinding means that all patients were only informed preoperatively that they would receive standard anesthesia and perioperative brain protection-related treatment, without being told the specific grouping and intervention measures. Evaluator blinding means that postoperative neurocognitive and brain function-related indicators were assessed by dedicated evaluators who did not participate in the anesthesia administration and were unaware of the grouping plan, and evaluators had no access to anesthesia records or grouping information throughout the process. |

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: |
设计统一病例报告表(CRF),由专人采集并记录患者基线资料、麻醉相关参数、围术期血流动力学指标、不良反应及术后谵妄随访数据;数据经双人核对后录入 Excel,建立电子数据库;全程实施质量控制,确保数据真实、完整、可追溯。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Unified Case Report Forms (CRFs) shall be designed. Specially-assigned personnel shall collect and record patients' baseline data, anesthesia-related parameters, perioperative hemodynamic indicators, adverse reactions and postoperative delirium follow-up data. All data shall be double-checked before being entered into Excel to establish an electronic database. Full-process quality control shall be implemented to guarantee the authenticity, completeness and traceability of all data. |
