Serial Doppler studies of the anterior cerebral artery were performed on 50 healthy term infants in the first 5 days of life. This study aims to establish a normative database for cerebral Doppler measurements in infants born appropriate for gestational age (AGA) and to compare them with those born small for gestational age (SGA). The difference between SGA and AGA infants was documented. In AGA infants, the Pourcelot's resistance index (PI) decreased over the first 5 days, while both the peak systolic flow velocity and end diastolic flow velocity increased. In SGA infants, the PI was significantly lower in the first 24 h of life. This was accounted for by an increase in the end diastolic flow velocity which may be a continuation of the intrauterine situation. The significance of the difference is discussed.
对50名足月健康婴儿在出生后的头5天内进行了大脑前动脉的连续多普勒研究。本研究旨在建立适合胎龄（AGA）出生婴儿脑多普勒测量的标准数据库，并将其与小于胎龄（SGA）出生的婴儿进行比较。记录了SGA和AGA婴儿之间的差异。在AGA婴儿中，普尔塞洛阻力指数（PI）在头5天内下降，而收缩期峰值流速和舒张末期流速均增加。在SGA婴儿中，出生后24小时内PI显著较低。这是由于舒张末期流速增加所致，这可能是子宫内情况的延续。讨论了差异的意义。
