Multi-channel aEEG in Cardiac Arrest Patients With Targeted Temperature Management

Neurological Prognostication Using Multi-channel Amplitude-integrated Electroencephalographic Monitoring in Cardiac Arrest Patients With Targeted Temperature Management

This study aims to examine the prognostic value of 18 channel amplitude-integrated EEG (aEEG) in comatose cardiac arrest patients The study design is a prospective observational study. Cardiac arrest patients undergoing targeted temperature management (TTM) will participate in the study. Relation of aEEG in each channel with the neurologic outcome at 6 month after return of spontaneous circulation (ROSC) will be evaluated.

Normal trace was defined as continuous cortical activity on the raw EEG scan; in addition, the upper margin of the aEEG scan, referred to as the aEEG maximum, was >10 μ V, and the lower margin of the aEEG scan, referred to as the aEEG minimum, was >5 μ V. The Time from ROSC to normal trace (TTNT, hours) is predictor of neurological outcome in these patients. We will evaluate the prognostic values of TTNTs in all aEEG channels.
