Pre-surgery intranasal dexmedetomidine or esketamine to reduce negative behaviors after anesthesia in children with autism

The Effects of Preoperative Intranasal Administration of Dexmedetomidine and Esketamine on Negative Postoperative Behavioral Changes in Children With Autism Spectrum Disorder

NA · Nanjing Children's Hospital · NCT07324057

We will test whether a single intranasal dose of dexmedetomidine or esketamine given before anesthesia can lower negative behavioral changes seven days after surgery in children aged 2–12 with autism.

What this trial studies

This randomized, double-blind, placebo-controlled multicenter trial will assign 234 children with autism spectrum disorder undergoing elective general anesthesia to intranasal dexmedetomidine, intranasal esketamine, or intranasal saline in a 1:1:1 ratio. Study medication is administered about 30 minutes before anesthesia and blinding is maintained for caregivers, clinicians, and outcome assessors. The primary outcome is negative postoperative behavioral changes measured seven days after surgery, with secondary outcomes including postoperative agitation, pain, sedation quality, safety events, and peri-recovery EEG patterns. Randomization is centrally managed with stratified block design by center, age group, and surgical category to balance groups.

Who should consider this trial

Good fit: Children aged 2–12 years with a psychiatrist-diagnosed autism spectrum disorder, ASA physical status I–III, scheduled for elective surgery under general anesthesia and meeting inclusion criteria are ideal candidates.

Not a fit: Children having cardiac, thoracic, or neurosurgery, or those with epilepsy, severe hepatic/renal dysfunction, recent sedative use, major comorbid psychiatric/neurologic disorders, severe upper respiratory infection, or other listed exclusions are unlikely to receive benefit from these interventions.

Why it matters

Potential benefit: If successful, this approach could reduce postoperative emotional distress and behavioral problems in autistic children recovering from surgery.

How similar studies have performed: Intranasal dexmedetomidine has shown benefit for reducing emergence agitation in pediatric populations, but direct comparisons with intranasal esketamine and focused evidence in children with autism are limited.
