随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机化法,按年龄(<75岁 / ≥75岁)和术前MMSE评分(≥24分 / <24分)进行分层。由不参与患者招募与评估的独立统计人员,使用R软件blockrand包,为每个分层生成长度为3、6、9的随机排列区组序列,共计生成150个分配号,确保三组最终例数1:1:1均衡。

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

A stratified block randomization method was adopted, with stratification performed by age (<75 years / >=75 years) and preoperative Mini-Mental State Examination (MMSE) score (>=24 points / <24 points). An independent statistician not involved in patient recruitment and assessment generated a randomly permuted block sequence with block lengths of 3, 6, and 9 for each stratum using the blockrand package in R software, producing a total of 150 allocation numbers to ensure a balanced 1:1:1 distribution of the final sample size across the three groups.

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:

干预涉及通气参数和不同升压药,对麻醉医生无法完全设盲。但至关重要的一点是,研究的主要终点术后谵妄评估者为麻醉科恢复室护士完全设盲。

Blinding:

The intervention involves ventilation parameters and different vasopressors, making complete blinding of anesthesiologists unfeasible. Critically, the nurses in the Post-Anesthesia Care Unit who assess postoperative delirium—the primary endpoint of the study—are fully blinded to the group assignments.

The raw data will be made publicly available following the publication of the paper. Requests for the data should be sent via email to the study registration contact person or the principal investigator.

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:

数据采集分为患者基础情况,术后三天内的随访为纸质记录表,而术中患者情况如心率,血压,血氧,呼气末二氧化碳,脑氧饱和度,大脑中动脉流速数据采集管理系统记录。

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

Data collection was divided into patient baseline conditions, and follow-up within three days after surgery was a paper record form, while intraoperative patient conditions such as heart rate, blood pressure, blood oxygen, end-tidal carbon dioxide, cerebral oxygen saturation, and blood pressure were recorded, middle cerebral artery velocity data were recorded by the data acquisition management system.
