The EEG Study Under Remimazolam Anesthesia in Children

Recruiting

• Conditions: Electroencephalography; Remimazolam; Child Neglect

• Registration Number: NCT06698705
• Lead Sponsor: Second Affiliated Hospital of Wenzhou Medical University

Brief Summary

The effect of Remimazolam on brain electrical activity. Previous studies have shown that in healthy male volunteers, EEG changes during Remimazolam infusion are characterized by an initial increase in the beta band and a later increase in the delta band. When monitoring the depth of anesthesia, the commonly used Bispectral Index in clinical practice was originally developed for propofol. Therefore, studies have shown that the correlation between the depth of sedation of benzodiazepines such as midazolam and Bispectral Index is weak. In contrast, the beta wave ratio is considered a more suitable EEG indicator for monitoring the sedative effect of Remimazolam. The above indicates that Remimazolam has a specific pattern of influence on EEG activity, especially in the regulation of anesthesia depth, with unique characteristics.

Detailed Description

This study is a prospective, observational study.Children undergoing elective general anesthesia with Remimazolam will be divided into three groups (1-3 years old, 4-6 years old, 7-12 years old) based on their age range, with 20 cases in each group.Inform the family of the general research plan and obtain informed consent. Main outcome measure: Time frequency characteristics of electroencephalography (EEG) in children of different age groups under general anesthesia withRemimazolam (including anesthesia induction, maintenance, and recovery periods).

Primary Outcome Measures

Name	Time	Method
Time-frequency characteristics of electroencephalogram (EEG)	Intraoperative (during remimazolam general anesthesia (including anesthesia induction, maintenance and recovery)	Time-frequency characteristics of electroencephalogram (EEG) in children of different ages during remimazolam general anesthesia (including anesthesia induction, maintenance and recovery) .

Secondary Outcome Measures

Name	Time	Method
Modified observer's assessment of alertness/sedation (MOAA/S)	Intraoperative (during remimazolam general anesthesia (including anesthesia induction, maintenance and recovery)	5#Subject responds readily to name spoken in a normal tone; 4 #Lethargic response of a subject to a name spoken in a normal tone; 3 #The subject responds only after a name is called loudly and repeatedly; 2 #The subject responds only after mild prodding or shaking; 1 #The subject responds only after a painful trapezius squeeze; 0 #The subject does not respond to painful trapezius squeeze. MOAA/S score ≤ 2 points represent successful sedation
Recovery time	Within up to 30 minutes after operation	From the time sevoflurane was stopped until the child opened his eyes for the first time and reached an Aldrete score of ≥9
Pediatric anesthesia emergence delirium	Within up to 30 minutes after operation	The pediatric anesthesia emergence delirium scale consists of four items. Each item is scored 0-4 yielding a total between 0 and 20. The degree of emergence delirium increased directly with the total score.
The Face, Legs, Activity, Cry, Consolability Scale (FLACC)	Within up to 30 minutes after operation	The FLACC scale consists of five items. Each item is scored 0-2 yielding a total between 0 and 10. The degree of pain increased directly with the total score.
