Understanding brain activity related to fentanyl and drug liking
Characterizing the EEG Signature of Fentanyl and Its Association With Drug Liking
Stanford University · NCT06699953
This study looks at how fentanyl affects brain activity and how that relates to how much people like the drug, focusing on adults who will receive fentanyl during surgery.

What this trial studies
This observational study aims to characterize an electroencephalogram (EEG) biomarker associated with fentanyl administration and explore its relationship with patients' perceptions of drug liking. Participants will be adults scheduled for general surgical procedures who will receive fentanyl as part of their anesthesia. The study will analyze brain activity through EEG to identify specific signals linked to the effects of fentanyl. By understanding these connections, researchers hope to gain insights into the neurobiological mechanisms underlying opioid use and preferences.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older scheduled for general surgery who will receive fentanyl for anesthesia.
Not a fit: Patients with a history of opiate abuse, severe chronic pain conditions, or contraindications for MRI will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to better understanding and management of opioid use and addiction, potentially informing safer prescribing practices.
How similar studies have performed: While studies have explored EEG biomarkers in relation to opioids, this specific approach focusing on fentanyl and drug liking is relatively novel.
