Which of the following can lower EEG amplitude
C i.e. Hypothermia - EEG activation (i.e. high frequency & low voltage activity) is seen in (Mn-"Small BBC In English Stimulates No Hypoxic Keets") i.e. Barbiturates (small dose), Benzodiazepines (small dose), Mild hypercapnia (TCO2), Inhalational agents (subanesthetic), Etomidate (small doses), sensory stimulation, N20, Hypoxia (early), ketamine. Here small = small, mild, early or subanesthetic dose. EEG depression is caused by (Mn- Marked Hypo) i.e. hypothermia, hypocapnia, Propofol and Opioids and all marked (i.e. marked hypoxia (late), marked hypercapnia, large dose of barbiturates, etomidate & inhalational agents (1-2 MAC).
N20
Ketamine
Hypothermia
Early hypoxia
