Anesthesia Neurodevelopmental Impact in Congenital Scoliosis Children

November 16, 2025 updated by: Lulu Ma, Peking Union Medical College Hospital

Long-term Effect of General Anesthesia Before School Age on Neurodevelopment in Children With Congenital Scoliosis

In the past, a large number of animal studies have suggested that anesthesia exposure has potential neurotoxic effects, resulting in persistent cognitive and behavioral deficits. At present, there is still a lack of sufficient clinical research evidence to prove whether anesthesia exposure has long-term effects on neurodevelopment. The existing clinical research data suggests that a single short-time anesthesia exposure in young children does not affect long-term neurodevelopmental outcomes. Early onset scoliosis, including congenital scoliosis, is a type of scoliosis deformity that occurs before the age of 10. Posterior scoliosis correction surgery is one of the common treatment. There is currently no research indicating the impact of early single or multiple long-duration anesthesia exposure on the neurological development of children with congenital scoliosis. The aim of this study is to determine the long-term effect of general anesthesia exposure on neurocognitive function and behavior in children with congenital scoliosis, in order to provide reference for related clinical work.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
full-scale intelligence quotient, FSIQ
Time Frame: At the time of collecting baseline demographic data
Measured by Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV)
At the time of collecting baseline demographic data

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
CBCL Total score, CBCL Internalizing score, CBCL Externalizing score
Time Frame: Within six months of WISC-IV assessment
Measured by Child Behavior Checklist (CBCL)
Within six months of WISC-IV assessment
Verbal Comprehension Index (VCI), Perceptual Reasoning/Organization Index (PRI/POI)
Time Frame: At the time of collecting baseline demographic data
Measured by Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV)
At the time of collecting baseline demographic data
SDQ total difficulties score, SDQ internalizing problems score, SDQ externalizing problems score, SDQ prosocial behavior score
Time Frame: Within six months of WISC-IV assessment
