To investigate changes of intracerebral blood flow velocity correlated to different behavioural states, pulsed Doppler measurements were performed on anterior cerebral artery in 12 preterm and term neonates under polygraphic recordings and in view of the infants' behavioural state. Under very strict definition of the behavioural states there were significant differences in the parameters Vm (+25%), Vd (+75%), and Vs (+11%) in active compared to quiet sleep state. MABP was not significantly different in all examined behavioural states. From our results we conclude that in further Doppler studies the infants' behavioural state at the time of measurement should be assessed carefully.
为研究与不同行为状态相关的脑内血流速度变化，对12例早产和足月新生儿的大脑前动脉进行了脉冲多普勒测量，同时进行多导记录并考虑婴儿的行为状态。在对行为状态进行非常严格的定义下，与安静睡眠状态相比，活动状态下的Vm（增加25%）、Vd（增加75%）和Vs（增加11%）参数存在显著差异。在所有检查的行为状态下，平均动脉血压（MABP）无显著差异。根据我们的结果，我们得出结论，在进一步的多普勒研究中，应仔细评估测量时婴儿的行为状态。
