Electroencephalogram Predicts Post-operative Delirium

Frontal-temporal EEG During Anesthesia Recovery Predicts Postoperative Delirium in Neurosurgery: a Single-center, Prospective, Observational Study

Sponsor

Beijing Sanbo Brain Hospital

Enrollment

137 participants

Start Date

Mar 1, 2025

Study Type

OBSERVATIONAL

Conditions

Brain Tumor Adult Neurosurgery Delirium - Postoperative

Summary

The goal of this observational study is to investigate the predictive value of sub-hairline electroencephalography (EEG) during anesthesia recovery for postoperative delirium (POD). The main question to be answered is: * Can sub-hairline EEG measured during anesthesia recovery serve as a reliable predictor of POD? Adult patients undergoing elective craniotomy and admitted to the ICU will be enrolled. Sub-hairline EEG will be monitored until ICU discharge.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is investigating whether brainwave (EEG) recordings taken before surgery can predict which patients are at risk of developing delirium (sudden confusion and disorientation) after brain surgery. The goal is to identify at-risk patients earlier so preventive steps can be taken. **You may be eligible if...** - You are 18 or older - You are scheduled for planned (non-emergency) brain surgery (neurosurgery) - You are in generally good health (low to moderate anesthesia risk, ASA I or II) - You can provide written consent **You may NOT be eligible if...** - You have a known neurological or psychiatric disorder (e.g., epilepsy, Parkinson's disease) - You already have cognitive impairment before surgery - You regularly take medications that affect the brain (e.g., antidepressants, antipsychotics) - You are pregnant or breastfeeding - You have had brain surgery in the last 12 months Talk to your doctor to see if this trial is right for you.

Interventions

DIAGNOSTIC_TESTSub-hairline EEG Monitoring

Participants will receive standard postoperative care as per institutional protocols, including neuromonitoring, delirium screening, and ICU management. The study will not alter or assign any treatments but will analyze the association between sub-hairline EEG parameters and postoperative delirium (POD) outcomes
