title: [Quantification of electroencephalogram continuity by 24-hour recording in very premature infants].
abstract: 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.
