目的探讨中度噪声对极早期早产儿睡眠的影响。方法对26例妊娠26 ~ 31周的VPI进行观察研究，对其声压级进行前瞻性测量并进行录像记录。根据声峰值高于背景噪声的信噪比对其进行识别和分类。Prechtl在声音峰值时的唤醒状态由两名不知道研究目的的观察者评估。睡眠/觉醒状态在声音峰值后的变化与随机选择的无声音峰值时期的自发变化进行了比较。结果共鉴定出598个孤立声峰，信噪比为5SNR
Aim To evaluate the impact of moderate noise on the sleep of very early preterm infants (VPI).Methods Observational study of 26 VPI of 26-31weeks' gestation, with prospective measurements of sound pressure level and concomitant video records. Sound peaks were identified and classified according to their signal-to-noise ratio (SNR) above background noise. Prechtl's arousal states during sound peaks were assessed by two observers blinded to the purpose of the study. Changes in sleep/arousal states following sound peaks were compared with spontaneous changes during randomly selected periods without sound peaks.Results We identified 598 isolated sound peaks (5SNR
