Effects of Transcutaneous Vagal Nerve Stimulation on Post-Surgical Return to Consciousness, Delirium, and Depression (tVNS)
26 maja 2026 zaktualizowane przez: Charles Hogue, Northwestern University
This study will examine whether noninvasive, transcutaneous vagal nerve stimulation (tcVNS) can help restore consciousness in patients in the operating room and the Post Anesthesia Care Unit (PACU).
The study will also investigate if tcVNS can expedite discharge from the PACU and examine whether tcVNS administerd in the PACU helps reduce delirium and depression after surgery.
The study will also evaluate whether tcVNS speeds cognitive recovery from emergence of anesthesia and surgery.

|---|---|
|
Aktywny komparator: tcVNS Stimulation (Intervention)
Transcutaneous vagal nerve stimulation (tcVNS)
|
The tcVNS device utilized in this study is not an implanted device, but rather is solely operated outside of the body by affixing it around the patient's ear.
The device delivers stimulation of the vagus nerve at designated intensity, interval, and frequency.
|
|
Pozorny komparator: Sham tcVNS stimulation (Control)
Sham transcutaneous vagal nerve stimulation (Sham tcVNS)
|
The stimulator is flipped upside down so that the participant does not receive stimulation of the vagal nerve.

Ramy czasowe: 24 Hours
|
Time in minutes to a Patient State Index (PSI) (Sedline Sedation Monitor) score of 85.
The PSI is a quantitative score derived from 4 channel EEG monitoring of the frontal and prefrontal cortex for assessing level of consciousnes during sedation and general anesthesia.
The score ranges from 0 (EEG supression) -100 (fully awake).
A PSI range of 25-50 indicates optimal hypnotic state for general anesthesia

It consists of 13 severity items (scored 0-3) and 3 diagnostic items (scored 0-2 or 0-3), with a maximum total score of 46.
