Intranasal Dexmedetomidine or Esketamine for Negative Postoperative Behavioral Changes in Children (PEDI-NPOBCs)

29 de abril de 2026 atualizado por: Sun Fei, Nanjing Children's Hospital

Exploring the Association of Perioperative Electroencephalographic Changes Following Preoperative Intranasal Dexmedetomidine or Esketamine With Negative Postoperative Behavioral Changes in Children Undergoing Day Surgery

The goal of this clinical trial is to learn whether intranasal dexmedetomidine or esketamine given before anesthesia can reduce negative postoperative behavioral changes in children undergoing day surgery. Negative postoperative behavioral changes may include anxiety, sleep problems, nightmares, irritability, or other unusual behaviors after surgery. This study will also examine whether changes in brain wave patterns during the perioperative period are related to these behavioral changes.

The main questions this study aims to answer are:

Does intranasal dexmedetomidine reduce negative postoperative behavioral changes in children after day surgery? Does intranasal esketamine reduce negative postoperative behavioral changes in children after day surgery? Are perioperative electroencephalographic (EEG) features associated with negative postoperative behavioral changes? Researchers will compare intranasal dexmedetomidine, intranasal esketamine, and normal saline to see whether these treatments differ in their effects on postoperative behavior and perioperative EEG features.

Participants will be randomly assigned to receive intranasal dexmedetomidine, intranasal esketamine, or intranasal normal saline about 30 minutes before anesthesia. They will receive routine perioperative monitoring, including EEG monitoring during surgery and recovery. They will also be assessed for sedation, pain, and emergence delirium. Follow-up assessments of postoperative behavioral changes will be completed on postoperative days 3, 7, and 28.

Descrição detalhada

This multicenter, prospective, randomized, double-blind, controlled clinical trial will evaluate whether preoperative intranasal dexmedetomidine or esketamine can reduce negative postoperative behavioral changes in children undergoing day surgery under general anesthesia. The study will also explore whether perioperative electroencephalographic (EEG) features are associated with these behavioral changes and may help explain the effects of the study drugs.

A total of 342 children undergoing elective day surgery will be enrolled across four centers. Eligible participants will be randomly assigned in a 1:1:1 ratio to receive intranasal dexmedetomidine 2.0 micrograms/kg, intranasal esketamine 1.0 mg/kg, or an equal volume of normal saline approximately 30 minutes before induction of anesthesia. Study medications will be prepared in identical, unlabeled nasal spray devices to maintain blinding. Participants, investigators, and outcome assessors will remain unaware of treatment assignment throughout the study.

After study drug administration, participants will undergo routine perioperative monitoring. Sedation will be assessed before surgery. During anesthesia and recovery, EEG and other perioperative clinical data will be collected. Postoperative assessments will include pain and emergence delirium. Negative postoperative behavioral changes will be evaluated on postoperative days 3, 7, and 28. The primary outcome is the incidence of negative postoperative behavioral changes on postoperative day 7. Secondary analyses will assess behavioral outcomes at postoperative days 3 and 28 and examine the relationship between perioperative EEG patterns and postoperative behavioral changes.

This study is designed to provide evidence on the comparative effects of intranasal dexmedetomidine and esketamine on postoperative behavioral recovery in children undergoing day surgery and to identify perioperative EEG markers that may be associated with adverse behavioral outcomes.
