研究目的:

通过观察在老年营养不良患者中S-氯胺酮持续泵注对术后认知功能的影响及围术期肠道菌群改变与术后认知功能障碍的关系,为此类患者临床药物应用及术后认知功能障碍相关机制探索提供参考。  

Objectives of Study:

By observing the impact of continuous infusion of S-ketamine on postoperative cognitive function in elderly patients with malnutrition, as well as the relationship between changes in the perioperative gut microbiota and postoperative cognitive dysfunction, we aim to provide a reference for the clinical application of drugs in such patients and to explore the mechanisms related to postoperative cognitive dysfunction.

盲法:

本研究采用单盲设计,试验对受试患者、评估者(随访人员和统计人员)设盲。麻醉后恢复室的麻醉医生、护士,病房医生、护士均不知道患者分组。在整个研究过程中(包括随访)不能对受试患者和受试患者家属揭盲。主治麻醉医生因为实验特殊性需要知道分组情况。

Blinding:

This study adopts a single-blind design. Blinding is applied to the enrolled patients, outcome assessors (including follow-up personnel and statisticians). Anesthesiologists and nurses in the post-anesthesia care unit (PACU), as well as ward physicians and nurses, are unaware of the group assignments. Unblinding is not permitted for the patients or their family members throughout the study period, including during follow-up. Due to the specific requirements of the intervention, the attending anesthesiologist is aware of the group allocation.

1. 研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰的载入病例报告表(CRF)。 2. 录入采用相应的数据库系统双人双机录入,之后对数据库进行两边比对。 3. 电子数据文件分类保存,并有多个备份保存于不同磁盘或介质上,妥善保存,防止损坏。

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

1. According to the original observation records of the subjects, the researchers loaded the data into the case report form timely, complete, correct and clear. 2. Input using the corresponding database system double-person dual-computer input, and then compare the two sides of the database. 3. Electronic data files are classified and saved, and multiple backups are saved on different disks or media to prevent damage.
