WebBIS values of 65–85 are recommended for sedation, whereas values of 40–60 are recommended for general anaesthesia. At BIS values of less than 40, cortical suppression becomes discernible in raw EEG as a burst suppression pattern (Fig. 10.40). 4. BIS measures the state of the brain, not the concentration of a particular drug. WebJul 6, 2024 · There is no consensus or data regarding whether it is best to titrate medication to target burst-suppression or simply the absence of seizures. Targeting a deeper level …

Burst suppression is an electroencephalography (EEG) pattern that is characterized by periods of high-voltage electrical activity alternating with periods of no activity in the brain. The pattern is found in patients with inactivated brain states, such as from general anesthesia, coma, or … See more The burst suppression pattern was first observed by Derbyshire et al. while studying effects of anesthetics on feline cerebral cortices in 1936, where the researchers noticed mixed slow and fast electrical activity … See more The pseudo-rhythmic pattern of burst suppression is dictated by extracellular calcium depletion and the ability of neurons to restore the concentration. Bursts are accompanied by … See more Because the burst suppression pattern is characteristic of inactivated brains, the pattern can be used as a marker for the level of coma a … See more Bursts are identifiable on EEG readings by their high amplitude (75-250μV), typically short period of 1–10 seconds, and have frequency ranges of 0–4 Hz (δ) and 4–7 Hz (θ). Suppression episodes are identifiable by their low amplitude (< 5μV) and typically long … See more http://www.neuroanesthesia.net/ep-manual.pdf photo thierry lhermitte
