We used a signal averager with light emitting diode goggles as the photostimulator to study the development of the visual evoked potentials in 40 normal neonates of between 23 and 42 weeks' gestation. All except two infants of less than 24 weeks' gestation had replicable visual evoked potentials. A negative peak of latency (mean (SD), 308 (21) msec) was present in all infants, but the development of the primary positive peak depended on maturity. Only infants of 37 weeks or more had a consistent positive peak of latency (mean (SD), 220 (22) msec). The practical simplicity and reliability of this technique has distinct advantages over previous conventional recording systems. Neonatal visual evoked potentials are shown to change with maturity.
我们使用带有发光二极管护目镜的信号平均器作为光刺激器,来研究40例孕龄在23至42周之间的正常新生儿视觉诱发电位的发育情况。除了两名孕龄小于24周的婴儿外,其他所有婴儿均可记录到可重复的视觉诱发电位。所有婴儿均出现一个潜伏期为负的峰值(均值(标准差),308(21)毫秒),但主要正峰值的发育情况取决于成熟度。只有孕龄37周及以上的婴儿才有一个潜伏期一致的正峰值(均值(标准差),220(22)毫秒)。与以往传统的记录系统相比,该技术在实际应用中的简便性和可靠性具有明显优势。研究表明,新生儿视觉诱发电位会随着成熟度而变化。
