Abstract
To analyze EEG features of burst-suppression soon after cerebral circulatory arrest, 14 rats subjected to 7 or 9 min of asphyxial cardiac arrest are divided into good and bad outcome groups with balanced number of animals based on 72-h neurological deficit score. Results show that both the amplitude of EEG suppression and the burst frequency are significantly different between two groups while the amplitude of bursts exhibits similar values. All these findings demonstrate a close prognostic relationship between electrical and behavioral recovery after asphyxia-induced brain injury.
