研究目的:

1.确定非肥胖患者(BMI 18.5~24.9 kg/m2)在固定剂量奥赛利定下,环泊酚用于无痛胃镜检查的ED50及ED95。 2.确定肥胖患者(BMI ≥28 kg/m2)在上述联合方案中环泊酚的ED50及ED95。 3.比较两组间环泊酚有效剂量的差异,评估肥胖患者对环泊酚需求量的影响。评价该联合方案在两类人群中的安全性(呼吸、循环不良事件及注射痛等)。  

Objectives of Study:

1. To determine the ED50 and ED95 of ciprofol for painless gastroscopy in non?obese patients (BMI 18.5–24.9 kg/m2) under a fixed dose of oliceridine. 2. To determine the ED50 and ED95 of ciprofol in the above combination regimen in obese patients (BMI ≥28 kg/m2). 3. To compare the difference in the effective dose of ciprofol between the two groups, evaluate the impact of obesity on ciprofol requirement, and assess the safety of this combination regimen in the two populations (respiratory and circulatory adverse events, injection pain, etc.).

干预措施:

序贯剂量分配采用Dixon上下法,患者均30s内静脉注射20μg/kg奥赛利定,随后静脉注射环泊酚,首例患者的环泊酚初始剂量为0.4mg/kg。根据胃镜置入过程中出现的咳嗽、呛咳或任何身体活动等表现,将环泊酚的使用定义为“反应阳性”,此时静脉注射0.1mg单次剂量的环泊酚并重复给药以完成胃镜检查,下一位受试者的单次剂量按0.05 mg/kg阶梯式递增;若胃镜检查顺利完成,则下一位受试者的剂量按0.05 mg/kg递减。将反应阳性组与非反应阳性组区间中点对应的环泊酚剂量定义为单次交叉试验的有效剂量,研究结束前共获得7个交叉点数据。

干预措施代码:

Intervention:

Sequential dose allocation was performed using the Dixon up-and-down method. All patients received an intravenous injection of 20 μg/kg oliceridine over 30 seconds, followed by intravenous ciprofol. The initial ciprofol dose for the first patient was 0.4 mg/kg. The use of ciprofol was defined as a "positive response" based on manifestations such as coughing, choking, or any body movement during gastroscope insertion. In such cases, a single dose of 0.1 mg ciprofol was administered intravenously and repeated to complete the gastroscopy, and the single dose for the next subject was increased stepwise by 0.05 mg/kg. If the gastroscopy was completed smoothly, the dose for the next subject was decreased by 0.05 mg/kg. The ciprofol dose corresponding to the midpoint of the interval between the positive response group and the non-positive response group was defined as the effective dose in a single crossover trial, and data from a total of seven crossover points were obtained before the end of the study.

Intervention:

Sequential dose allocation was performed using the Dixon up-and-down method. All patients received an intravenous injection of 20 μg/kg oliceridine over 30 seconds, followed by intravenous ciprofol. The first obese patient received an initial ciprofol dose of 0.4 mg/kg based on adjusted body weight. The use of ciprofol was defined as a "positive response" based on manifestations such as coughing, choking, or any body movement during gastroscope insertion. In such cases, a single dose of 0.1 mg ciprofol was administered intravenously and repeated to complete the gastroscopy, and the single dose for the next subject was increased stepwise by 0.05 mg/kg.
