Sevoflurane's Effect on Neurocognition Study
NCT06044740 · Status: COMPLETED · Phase: EARLY_PHASE1 · Type: INTERVENTIONAL · Enrollment: 42
Last updated 2026-04-15
Summary
The purpose of this study is to determine the effects of acute pain on long-term memory and conditioned physiologic responses in the presence and absence of low dose sevoflurane. Functional magnetic resonance imaging will be used to identify the neural correlates of these phenomena. The study will occur over 2 visits and involves no long-term follow up.
Conditions
- Anesthesia
- Pain
- Amnesia
Interventions
- DRUG
-
Sevoflurane
After a no-drug control period, subjects will inhale sevoflurane, administered via a breathing circuit and face mask, until a steady-state target end-tidal expired concentration of 0.4% (corresponding to 0.2 Minimum Alveolar Concentration) is reached.
- DEVICE
-
Peripheral Nerve Stimulation
Experimental acute pain stimulus will be delivered using a nerve stimulator. These painful shocks will be paired with a fixed number of the experimental cues, in a pattern that appears random to participants.
