115 pain-induced cries from 45 full-term newborn infants with pre- and perinatal asphyxia were analyzed by sound spectrographic methods. All the infants had signs of intrauterine asphyxia and Apgar score of 6 or less at 5 min. The mean birth weight was 3170 g. The pain cries were recorded before the age of 8 days, 83% of the cries before 3 days of age. The cry analysis was compared with the pain cries of 75 full-term, healthy newborn infants of corresponding birth weight and gestational age. The results showed significant differences between the cries of the asphyxiated newborn and the healthy infants. The duration of the phonation was shorter, the maximum and minimum pitch of the fundamental frequency was significantly higher. Bi-phonation and vibrato occurred more often, double harmonic break and glottal roll less often. An increase in rising, falling-rising and flat types of melody was observed. Retrospectively, the cries were more abnormal if the infant was found to be neurologically damaged at t he check-up at 2-8 years.
采用声谱分析法对45例有产前和围产期窒息的足月儿的115次因疼痛引起的啼哭进行了分析。所有婴儿均有宫内窒息体征，且5分钟时阿氏评分≤6分。平均出生体重为3170克。疼痛啼哭记录于出生8天之前，83%的啼哭发生在出生3天之前。将这些啼哭分析结果与75例出生体重和胎龄与之相应的足月儿健康新生儿的疼痛啼哭进行了比较。结果显示，窒息新生儿与健康婴儿的啼哭存在显著差异。发声持续时间较短，基频的最大和最小音高显著更高。双声和颤音出现得更频繁，双谐波中断和声门滚动出现得较少。观察到上升、升降和水平旋律类型增加。回顾性分析发现，如果婴儿在2至8岁的检查中被发现有神经损伤，则其啼哭更异常。
