研究目的:

1.主要目的: 在标准化平衡麻醉背景下,采用BCD序贯剂量探索设计,明确1-6岁儿童日间腹腔镜疝囊高位结扎术中阿芬太尼单次静脉给药达到复合有效麻醉反应的ED90及其95%置信区间,并同步完成阶段1的有效性判定与安全性监测。 2.次要目的: 在推荐剂量(RD)下验证复合有效反应率是否达到预设标准(≥90%),并描述不同年龄层结果。 评价快速康复相关指标:自主呼吸恢复时间、拔管时间、PACU停留时间、离院达标时间、术后疼痛(FLACC)及72h内再就诊/再入院等。  

Objectives of Study:

1. Primary Objective: Under standardized balanced anesthesia and using a biased coin design (BCD) sequential dose-finding design, to determine the ED90 and its 95% confidence interval of a single intravenous dose of alfentanil for achieving a composite effective anesthetic response in children aged 1–6 years undergoing day-case laparoscopic high ligation of the hernial sac, and to concurrently complete the efficacy assessment and safety monitoring of Stage 1. 2. Secondary Objectives: To verify whether the composite effective response rate at the recommended dose (RD) meets the prespecified criterion (≥90%), and to describe the results across different age groups. To evaluate enhanced recovery?related indicators: time to spontaneous breathing recovery, extubation time, length of stay in the post?anesthesia care unit (PACU), time to discharge readiness, postoperative pain (FLACC), and return visits/rehospitalizations within 72 hours, etc.
