研究目的：

1. 确定泰吉利定（Tegileridine）与环泊酚（Cypofol）联合用于无痛胃镜检查时，抑制胃镜插入反应的50%有效剂量（ED50）和95%有效剂量（ED95）。 2. 探索“富马酸泰吉利定+环泊酚”作为门诊无痛胃肠镜麻醉的标准化流程，为门诊舒适化诊疗提供新的麻醉方案参考。 3. 基于研究结果，为老年患者门诊无痛胃肠镜麻醉提供一种更安全、更优化的镇痛-镇静联合用药方案的循证医学依据。  

Objectives of Study：

1. Determine the 50% effective dose (ED50) and 95% effective dose (ED95) of Tegileridine combined with Cypofol for inhibiting the gastroscopy insertion reaction during painless gastroscopy. 2. Explore the use of "Telitacilic acid + Ciboprofen" as a standardized process for outpatient painless gastroscopy anesthesia, providing a new anesthesia protocol reference for outpatient comfortable diagnosis and treatment. 3. Based on the research results, provide evidence-based medical support for a safer and optimized combined analgesia-sedation medication regimen for outpatient painless gastroscopy anesthesia in elderly patients.

干预措施：

本研究使用改良Dixon序贯法测量药物的半数有效剂量，如果插入胃镜反应阳性，则下一例泰吉利定的剂量增加一个浓度梯度；如果插入胃镜反应阴性，则下一例泰吉利定的剂量降低一个浓度梯度，确定出现了插管反应阳性的病例序号以及该序号的剂量，而入选病例以出现插管反应阳性的前1例患者开始计算，直至出现插入胃镜阴性反应与阳性反应交替8个转折点结束实验，总例数则为研究例数。按年龄将患者分为青年组（18～44岁）、中年组（45～64岁）、老年组（>=65岁），三组独立进行序贯剂量滴定。所有患者均给予固定剂量环泊酚0.3 mg/kg静脉注射，联合滴定不同剂量泰吉利定。以胃镜操作过程中无体动、无呛咳、无躁动为有效判定终点，记录有效/无效结果并序贯调整下一例给药剂量。青年组起始剂量10 μg/kg，剂量梯度1.0 μg/kg。

干预措施代码：

Intervention：

This study employed the modified Dixon sequential method to measure the half-maximal effective dose of the drug. If the gastroscopy insertion response was positive, the dose of the next case of tizoxanide was increased by one concentration gradient; if the gastroscopy insertion response was negative, the dose of the next case of tizoxanide was decreased by one concentration gradient. The case number and dose corresponding to the positive gastroscopy insertion response were determined. The enrolled cases were counted from the first case with a positive gastroscopy insertion response until the experiment ended with eight turning points alternating between negative and positive gastroscopy insertion responses. The total number of cases was the number of study cases. Patients were divided into three groups based on age: young group (18-44 years old), middle-aged group (45-64 years old), and elderly group (>=65 years old). Sequential dose titration was conducted independently in each group. All patients received a fixed dose of 0.3 mg/kg of propofol intravenously, combined with titration of different doses of tizoxanide. The effective endpoint was defined as no body movement, no coughing, and no agitation during gastroscopy. Effective/ineffective results were recorded, and the next dose was sequentially adjusted. The starting dose for the young group was 10 μg/kg, with a dose gradient of 1.0 μg/kg.

This study employed the modified Dixon sequential method to measure the median effective dose of the drug. If the gastroscopy insertion response was positive, the dose of the next case of tizoxanide was increased by one concentration gradient; if the gastroscopy insertion response was negative, the dose of the next case of tizoxanide was decreased by one concentration gradient.
