研究目的:

本研究拟分两个阶段开展。 第一阶段采用剂量探索设计,分别测定艾司氯胺酮和瑞芬太尼辅助环泊酚镇静在肥胖患者胃肠镜检查中的有效剂量参数,明确两种药物在该人群中的剂量反应关系,并为后续随机对照试验确定研究剂量。 第二阶段在前期剂量探索结果基础上,开展随机对照试验,比较艾司氯胺酮与瑞芬太尼辅助环泊酚镇静对肥胖患者胃肠镜检查中低氧血症发生的影响,同时评价两种方案的镇静效果与安全性。  

Objectives of Study:

This study is planned to be conducted in two phases. Phase 1 will employ a dose-finding design to determine, respectively, the effective dose parameters of esketamine and remifentanil as adjuncts to cipofol sedation in obese patients undergoing gastrointestinal endoscopy, to elucidate the dose-response relationships of both agents in this population, and to establish the doses for the subsequent randomized controlled trial. Phase 2, building on the results of the preceding dose-finding phase, will conduct a randomized controlled trial to compare the effect of esketamine versus remifentanil as adjuncts to cipofol sedation on the incidence of hypoxemia in obese patients undergoing gastrointestinal endoscopy, and to evaluate the sedative efficacy and safety of the two regimens.

盲法:

研究第一阶段:对受试者、内镜医生、结局评估者和数据分析人员设盲;麻醉实施者因承担实时安全管理职责不设盲,但不参与结局评估。艾司氯胺酮和瑞芬太尼的剂量调整由独立研究人员依据改良Dixon序贯法执行,麻醉医生不参与剂量决策。 研究第二阶段:对受试者、内镜医生、结局评估者和数据分析人员设盲;麻醉实施者因承担实时安全管理职责不设盲,但不参与结局评估。

Blinding:

Study Phase I Patients, endoscopists, outcome assessors, and data analysts will be blinded. The anesthesiologist administering sedation will not be blinded, given the responsibility for real-time safety management, but will not participate in outcome assessment. Dose adjustments of esketamine and remifentanil will be carried out by an independent researcher according to the modified Dixon sequential method, and the anesthesiologist will not be involved in dose decisions. Study Phase II Patients, endoscopists, outcome assessors, and data analysts will be blinded. The anesthesiologist administering sedation will not be blinded, given the responsibility for real-time safety management, but will not participate in outcome assessment.
