Official title

Electroencephalogram Studies of Induction and Recovery From Ketamine-Induced General Anesthesia

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

We are doing this research study to find out how and where ketamine acts in the brain. Ketamine is an anesthetic (a drug or agent used to decrease or eliminate the feeling of pain by putting you in an unconscious state). We will look at the brain using a machine that records the brain's electrical activity, called an electroencephalogram (EEG). We will assess how it impacts patient's pain responses.
