EEG: high dose opiates

Pharmacology, Physiology - Neurologic

Opioids produce a dose related decrease in the frequency and amplitude of the EEG.

Low dose opioids show a loss of beta waves and a slowing of alpha waves.

Moderate dose opioids show diffuse theta waves and some delta waves.

High dose opioids show delta waves (high amplitude, 0-4 Hz) . See [Delta Waves] on Wikipedia.

Unlike with volatile gases, barbituates, and propofol, complete isoelectric EEG waves cannot be obtained, even with high dose opioids.
