In 121 healthy premature born infants, full-term newborns and older infants (gestational age: 29 to 45 weeks; weight at investigation: 1070 g to 3750 g), the flow velocities in the internal carotid arteries were measured by pulsed doppler sonography. All infants were investigated by computer sonography (Acuson 128) with a 5 MHz transducer. The following parameters were measured: The maximal systolic velocity, the end-systolic and end-diastolic velocity as well as the mean flow velocities, the pulsatility-index and the resistance-index. For all parameters the relationship to the gestational age and weight were analysed. All flow velocities increased linearly with increasing gestational age and weight. In contrast to the flow velocities neither the pulsatility-index nor the resistance-index changed with increasing gestational age and weight. As flow velocities in the internal carotid arteries increase with increasing gestational age and weight these parameters must be taken into consideration when pathologic flow velocities are analysed.
在121名健康的早产婴儿、足月儿和较大婴儿（胎龄：29至45周；检查时体重：1070克至3750克）中，通过脉冲多普勒超声测量颈内动脉的血流速度。所有婴儿均使用5兆赫探头通过电脑超声（Acuson 128）进行检查。测量了以下参数：最大收缩期速度、收缩末期和舒张末期速度以及平均血流速度、搏动指数和阻力指数。分析了所有参数与胎龄和体重的关系。所有血流速度均随胎龄和体重的增加而呈线性增加。与血流速度不同，搏动指数和阻力指数均不随胎龄和体重的增加而变化。由于颈内动脉的血流速度随胎龄和体重的增加而增加，因此在分析病理性血流速度时必须考虑这些参数。
