Detailed Description

BrainICU is a prospective observational study investigating the EEG slow wave activity in comatose cardiac arrest survivors under propofol anesthesia and its association with neurological outcome. Comatose adult patients admitted to intensive care unit (ICU) after cardiac arrest are included. Patients with previous neurological disease expected to affect substantially the EEG are excluded. The patients' relatives are asked for an informed written consent to participate. In the intensive care, the patients are sedated using continuous infusion of propofol while receiving temperature management/hypothermia treatment following the ICUs' common practice. EEG is recorded within the first 24h after ICU admission. If possible, the recording is repeated on the second and third day i.e. 48h and 72h after ICU admission, respectively. To induce the maximum effect of propofol on EEG, additional boluses of propofol during the EEG recording may be given until the burst suppression level is reached. Slow wave activity is calculated offline from the EEG recordings. The neurological recovery of the patients is defined 6 months after cardiac arrest from patient documents and/or by phone call to the patient/ relative using Cerebral Performance Category. After the follow-up period patient or the relative is also asked to fill a survey (SF-36) to estimate the health and quality of life.
