Burst suppression EEG displaying alternating high-amplitude bursts and flat suppression periods. Burst suppression is a pattern observed in EEG recordings, showing alternating periods of high-amplitude brain activity (bursts) and low-amplitude or flatline activity (suppression). This pattern is often seen in patients under deep anesthesia and may indicate excessive sedation.
Understanding postoperative delirium
Postoperative delirium manifests as sudden and fluctuating cognitive disturbances following surgery. Clinically, POD is linked to increased morbidity, mortality, prolonged hospital stays, and higher medical expenses. Other complications—such as intraoperative awareness and hypotension—also pose significant health risks and strain healthcare resources. Researchers have identified "burst suppression"—periods of alternating high and low brain activity detectable via EEG during anesthesia—as a potential predictor of POD. Accurate EEG monitoring emerges as an essential tool in mitigating these risks.
