连续脑电图（EEG）睡眠研究获得了健康的足月和早产儿在匹配的概念年龄。研究是在环境控制条件下进行的。根据受孕年龄、性别、种族和社会经济阶层，将18名健康早产儿与18名足月儿相匹配。12小时记录中的前3小时同时记录在纸上和计算机上。视觉评分数据的基础上的纸记录睡眠结构和连续性措施进行了研究。早产儿的每种睡眠组织的差异包括以下内容：注意到更长的超昼夜睡眠周期（70分钟对53分钟，p = 0.02）。注意到更丰富的痕量交替（34%对28%，p = 0.02）和更少的低电压不规则主动睡眠（13%对17%，p = 0.05）。尽管在睡眠潜伏期和效率方面没有观察到差异，但早产儿的觉醒次数和持续时间更少，身体运动和快速眼动（REM）更少（p < 0.01），特别是在安静睡眠期间。与经历完整宫内妊娠的足月婴儿的睡眠相比，早产儿的宫外经历或早期出生可能会影响特定的睡眠结构和连续性测量。
Continuous electroencephalogram (EEG) sleep studies were obtained on healthy full-term and preterm infants at matched conceptional ages. Studies were recorded under environmentally controlled conditions. Eighteen healthy preterm infants were matched to 18 full-term infants based on conceptional age, sex, race and socioeconomic class. The initial 3 hours of a 12-hour recording were simultaneously recorded on paper and computer. The visually scored data based on the paper recordings for sleep architecture and continuity measures were studied. Differences in each sleep organization for the preterm infants included the following: a longer ultradian sleep cycle (70 minutes vs. 53 minutes, p = 0.02) was noted. More abundant trace alternant (34% vs. 28%, p = 0.02) and less abundant low-voltage irregular active sleep (13% vs. 17%, p = 0.05) were noted. Although no differences were observed for sleep latency and efficiency, the preterm infants had fewer numbers and shorter durations of arousals, fewer body movements and rapid eye movement (REM) (p < 0.01), particularly during quiet sleep. The extrauterine experience or the earlier birth of the preterm infant may influence specific sleep architecture and continuity measures when compared with the sleep of full-term infants who experienced a complete intrauterine gestation.
