Objectives of Study: |
The objective is to investigate whether the application of permissive hypercapnia in elderly patients undergoing gastrointestinal tumor surgery can increase intraoperative cerebral oxygen saturation and cerebral blood flow, reduce the incidence of postoperative cognitive dysfunction, and improve the quality of patient recovery. |

Exclusion criteria: |
(1)The preoperative Montreal Cognitive Assessment (MoCA) score <24, patients with history of cerebrovascular disease, epilepsy, Parkinson's disease and myasthenia gravis; (2) severe cardiac function (NYHA class > Ⅲ or LVEF < 30%), respiratory function, liver and kidney dysfunction. (3) poorly controlled diabetes and hypertension. (4) patients who are expected to need postoperative intubation and thus unable to perform cognitive assessment; (5) patients who were allergic to or had contraindications to the drugs used during the study; (6) patients who participated in other drug trials within 1 month before planned surgery |

随机方法(请说明由何人用什么方法产生随机序列): |
采用随机数字表法:从随机数字表中任意起点(如第10行第5列)开始,按横向顺序读取200个随机数字,对每个患者的编号(1~200)匹配对应的随机数字,计算余数并分组。随机数字除以2,余数 0→实验组,余数 1→对照组。若实验组与对照组比例接近 1:1(允许±5%差异),直接采用;若差异过大,补充随机数调整。参与随机化分配的研究人员为独立人员,不参与研究的其他过程。随机分组结果需由随机化专员专门记录并妥善保存。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Using the random number table method: Starting from an arbitrary point in the random number table (e.g., row 10, column 5), sequentially read 200 random numbers in a horizontal direction. Match each patient's number (1~200) with the corresponding random number, calculate the remainder, and assign groups accordingly. Divide the random number by 2: remainder 0 → experimental group, remainder 1 → control group. If the ratio between the experimental group and the control group is close to 1:1 (allowing a ±5% difference), proceed directly; if the difference is too large, adjust by supplementing additional random numbers.The researchers involved in randomized allocation are independent individuals and do not participate in other research processes. The random grouping results need to be specifically recorded and properly stored by the randomization specialist. |

公开/Public |
|
盲法: |
研究对象签署知情同意书,入手术室后,麻醉医生打开一个包含随机分组情况的不透明密封信封,严格执行研究方案。由于麻醉医生知晓分组情况,故不参与数据收集与统计工作。患者、参加数据收集和统计分析的研究人员、实施外科手术的人员、麻醉恢复室医师及护理人员均不清楚分组情况。统计工作由专业的统计人员完成。 |
|
Blinding: |
After the study participants signed the informed consent form and entered the operating room, the anesthesiologist opened an opaque sealed envelope containing the randomized group assignment and strictly implemented the study protocol. Since the anesthesiologist was aware of the group assignments, they did not participate in data collection or statistical analysis. The patients, researchers involved in data collection and statistical analysis, surgical team members, recovery room physicians, and nursing staff were all blinded to the group assignments. The statistical analysis was conducted by a professional statistician. |

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: |
所有研究数据由课题组专员负责采集记录,病例记录表完成后将于指定地点妥善保存,并保证只有课题组相关人员可以查阅。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
All research data will be collected and recorded by designated personnel from the research team. Once the case report forms are completed, they will be securely stored at a designated location, ensuring that only authorized members of the research team have access to them. |
