Long-term cassette EEG monitoring in the neonatal intensive care unit has established prognostic criteria regarding the developmental outcome by quantifying seizure activity. The clinical significance of the organization of continuous and discontinuous EEG patterns in the early premature is still an open question. This report presents quantified EEG data from repeated 24 h records during the first week of life in premature infants (conceptional age less than 32 weeks) with and without ultrasound evidence of intracerebral hemorrhage. The repartition and evolution of EEG background activity is not a reliable parameter regarding pathology. The continuity index is rather a maturational variable and its ultradian fluctuation is an early expression of the "basic rest activity cycle" (BRAC) rhythm.
新生儿重症监护病房中的长期盒式脑电图监测通过量化癫痫活动，确立了有关发育结局的预后标准。早期早产儿连续和不连续脑电图模式的组织的临床意义仍是一个悬而未决的问题。本报告展示了出生后第一周内对早产儿（孕龄小于32周）进行的重复24小时记录的量化脑电图数据，这些早产儿有或没有脑内出血的超声证据。脑电图背景活动的分布和演变并非判断病理情况的可靠参数。连续性指数更像是一个成熟变量，其超日波动是“基本静息活动周期”（BRAC）节律的早期表现。
