Can brain waves predict a smooth Wake-Up from anesthesia?
NCT ID NCT07806903
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
This study tracks brain wave patterns in 140 adults as they wake from general anesthesia. Researchers compare two anesthesia methods: inhaled gases and intravenous drugs. They aim to see if certain brain wave patterns relate to recovery quality and early complications like agitation or nausea. The findings could help doctors tailor anesthesia and improve post-surgery care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could improve how doctors monitor anesthesia recovery and reduce complications like agitation or confusion after surgery.
- What could go wrong
- This is an observational study, so it cannot prove cause and effect. Results may not apply to all patients or surgeries.

Who is studied
This study will enroll adult patients aged 18-60 years who are scheduled to undergo elective non-cardiac and non-neurosurgical surgery under general anesthesia. Participants will receive routine clinical anesthesia management, and the choice of total intravenous anesthesia or inhalational anesthesia will be determined by the attending anesthesiologist according to clinical practice.

Inclusion criteria 1. Adults aged 18-60 years. 2. Patients classified as American Society of Anesthesiologists (ASA) physical status I-III. 3. Patients scheduled to undergo elective non-cardiac and non-neurosurgical surgery under general anesthesia. 4. Expected duration of surgery ≥60 minutes. 5. Expected intraoperative maintenance anesthesia with either total intravenous anesthesia (TIVA) or inhalational anesthesia . 6. Patients who understand the study procedures and voluntarily provide written informed consent. Exclusion Criteria 1. History of central nervous system disorders, including epilepsy, Parkinson's disease, dementia, previous stroke with residual neurological deficits, or other clinically significant neurological diseases. 2. Long-term use (≥4 weeks) of sedative-hypnotic drugs, antidepressants, antipsychotic medications, or other medications that may significantly affect central nervous system function. 3. Pre-existing cognitive impairment or severe visual/hearing impairment preventing assessment of recovery of consciousness. 4. Skin lesions, trauma, or other conditions affecting placement of frontal EEG electrodes. 5. Emergency surgery, neurosurgery, cardiac surgery, planned deep sedation with postoperative intubation, or direct transfer to the intensive care unit after surgery. 6.
