With the widespread use of electroencephalogram [EEG] monitoring during surgery or in the Intensive Care Unit [ICU], clinicians can sometimes face the pattern of burst suppression [BS]. The BS pattern corresponds to the continuous quasi-periodic alternation between high-voltage slow waves [the bursts] and periods of low voltage or even isoelectricity of the EEG signal [the suppression] and is extremely rare outside ICU and the operative room. BS can be secondary to increased anesthetic depth or a marker of cerebral damage, as a therapeutic endpoint [i.e., refractory status epilepticus or refractory intracranial hypertension]. In this review, we report the neurophysiological features of BS to better define its role during intraoperative and critical care settings.
随着脑电图（EEG）监测在手术中或重症监护病房（ICU）中的广泛应用，临床医生有时会面临爆发抑制（BS）模式。BS 模式对应于 EEG 信号的高压慢波（爆发）和低压或甚至等电期间的连续准周期性交替[抑制]，在 ICU 和手术室之外极为罕见。BS 可能继发于麻醉深度增加或脑损伤的标志物，作为治疗终点（即难治性癫痫持续状态或难治性颅内高压）。在这篇综述中，我们报告了 BS 的神经生理特征，以更好地定义其在术中和重症监护环境中的作用。
