研究目的:

本研究通过Dixon上下序贯法研究小儿利多卡因减少丙泊酚注射痛的有效剂量,为临床用药选择提供参考,为小儿利多卡因-丙泊酚使用提供操作规范。减少小儿丙泊酚注射痛,助力儿童舒适化医疗,提高儿童临床麻醉和治疗的质量。(1) 首要目标:采用Dixon上下序贯法测定 2~7岁小儿静脉预注射利多卡因减轻丙泊酚注射痛的中位有效剂量(ED₅₀)及95%有效剂量(ED₉₅)。(2) 次要目标:建立小儿利多卡因剂量-效应曲线,为小儿利多卡因-丙泊酚使用提供操作规范参考。  

Objectives of Study:

This study employed Dixon’s up-and-down sequential method to investigate the effective dose of lidocaine for reducing propofol injection pain in pediatric patients, aiming to provide a reference for clinical drug selection and establish operational guidelines for the combined use of lidocaine and propofol in children. By mitigating propofol injection pain, this research seeks to support comfort-oriented medical care for children and enhance the quality of pediatric clinical anesthesia and treatment.(1) Primary Objective: To determine the median effective dose (ED₅₀) and the 95% effective dose (ED₉₅) of intravenous lidocaine pretreatment for alleviating propofol injection pain in children aged 2 to 7 years using Dixon’s up-and-down sequential method.(2) Secondary Objective: To establish the dose-response curve for lidocaine in pediatric patients, thereby providing a reference for operational guidelines on the use of lidocaine-propofol in children.

丙泊酚注射痛复合疼痛评分

指标类型:

主要指标

Outcome:

Composite pain score for propofol injection pain

Type:

Primary indicator

测量时间点:

术中

测量方法:

丙泊酚注射痛复合疼痛评分表评分,疼痛评分>2则认为阳性(即干预无效),疼痛评分≤2,认为阴性(即干预有效)。

Measure time point of outcome:

Intraoperative

Measure method:

Propofol injection pain was assessed using a composite pain score (typically ranging from 0 to X, incorporating criteria such as facial expression, crying, and body movement). A score greater than 2 was defined as a positive outcome (indicating ineffective intervention), while a score equal to or less than 2 was defined as a negative outcome (indicating effective intervention)
