研究目的:

?本研究旨在通过偏倚硬币设计上下序贯法(Biased Coin Design Up-and-Down Sequential Method, BCD-UDM),分别确定环泊酚(复合固定剂量艾司氯胺酮)在老年衰弱与非衰弱患者无痛胃镜检查中,实现成功镇静(即抑制操作引起的体动反应)的90%有效剂量(ED90),并对两组的ED90进行比较分析。  

Objectives of Study:

This study aims to determine the 90% effective dose (ED90) of ciprofol (combined with a fixed dose of esketamine) for achieving successful sedation (i.e., suppressing movement responses induced by the procedure) during painless gastroscopy in elderly frail and non-frail patients, respectively, using the Biased Coin Design Up-and-Down Sequential Method (BCD-UDM). Additionally, the ED90 values between the two groups will be compared and analyzed.

本研究采用标准化病例记录表(Case Record Form, CRF)进行数据采集,内容包括受试者一般资料、麻醉用药信息、术中生命体征、药效学反应、术后不良反应等。数据由经过培训的研究人员双人独立录入,采用电子数据采集系统(Electronic Data Capture, EDC)进行管理,设置数据核查、逻辑校验、权限控制等功能,确保数据的真实性、完整性与可追溯性。所有数据严格保密,仅授权研究人员可访问,研究结束后按规定存档。

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

This study uses a standardized Case Record Form (CRF) for data collection, including subjects' general information, anesthesia medication details, intraoperative vital signs, pharmacodynamic responses, postoperative adverse reactions, etc. Data are independently entered by two trained researchers, and managed through an Electronic Data Capture (EDC) system with functions such as data verification, logical check, and access control to ensure the authenticity, integrity and traceability of data. All data are strictly confidential, accessible only to authorized researchers, and archived in accordance with regulations after the study.
