We aimed to quantify electroencephalogram (EEG) continuity for 24 hours in very premature infants. A total of 122 days of continuous two-channel EEG recordings were performed in 28 premature infants from 26 to 33 weeks of conceptional age (CA). None of the infants showed any evidence of neurological impairments during the course of their hospitalizations and showed normal neurological outcome. The 24-hour EEG recording was divided into 5.5-minute periods. The EEG of each period was classified into five EEG categories according to EEG continuity, and the percentage of each of them during the 24-hour recording was calculated. The percentages of continuous and continuous dominant EEG categories were increased with increasing CA. On the other hand, the percentages of discontinuous and discontinuous dominant EEG categories were decreased with increasing CA.
我们旨在对极早产儿的脑电图（EEG）连续性进行24小时量化。对28名孕龄（CA）为26至33周的早产儿进行了总共122天的连续双道EEG记录。所有婴儿在住院期间均未显示任何神经功能障碍的迹象，且神经学结局正常。24小时EEG记录被分为5.5分钟的时间段。根据EEG连续性，将每个时间段的EEG分为五个EEG类别，并计算它们在24小时记录中的各自百分比。连续和连续优势EEG类别的百分比随CA增加而增加。另一方面，不连续和不连续优势EEG类别的百分比随CA增加而降低。
