Abstract

Changes in forehead skin blood flow during active and quiet sleep were determined in 16 healthy neonates using a recently developed semi-conductor laser Doppler flow meter with-out light conducting fibres. Measurements were carried out at a postnatal age varying from 5 hours to 7 days. The two sleep states could be distinguished in 17 recordings. The mean skin blood flow values during active sleep were significantly higher (p less than 0.01) than those during quiet sleep, the mean increase being 28.1%. The variability of the flow signal, expressed as the coefficient of variation, changed significantly from 23.1% during active sleep to 18.2% during quiet sleep.

摘要

使用一种最近开发的不带光导纤维的半导体激光多普勒流量计，对16名健康新生儿在主动睡眠和安静睡眠期间前额皮肤血流的变化进行了测定。测量在出生后5小时至7天的不同年龄段进行。在17次记录中可以区分出两种睡眠状态。主动睡眠期间的平均皮肤血流值显著高于安静睡眠期间（p小于0.01），平均增加28.1%。以变异系数表示的血流信号变异性从主动睡眠期间的23.1%显著变化至安静睡眠期间的18.2%。
