Abstract

Doppler ultrasound was used to measure left renal artery blood flow velocity and pulsatility index on the first, third, and seventh day of postnatal life in 18 very low birthweight small for gestational age (SGA) infants. The values were compared with those from 18 weight matched and 18 gestation matched controls. SGA infants had significantly lower blood flow velocity than their gestation matched controls throughout the first postnatal week (day 1: SGA 10 cm/s, controls 15 cm/s; day 7: SGA 17 cm/s, controls 28 cm/s). These data suggest that abnormalities of renal artery blood flow velocity persist after delivery in the SGA infant.

摘要

对18例出生体重极低的小于胎龄(SGA)婴儿在出生后第1天、第3天和第7天使用多普勒超声测量左肾动脉血流速度和搏动指数。将这些值与18例体重匹配和18例孕周匹配的对照组的值进行比较。在出生后的第一周,SGA婴儿的血流速度显著低于孕周匹配的对照组(第1天:SGA为10厘米/秒,对照组为15厘米/秒;第7天:SGA为17厘米/秒,对照组为28厘米/秒)。这些数据表明,SGA婴儿出生后肾动脉血流速度异常持续存在。
