Abstract
The normal adult values for RBF cannot be used in infants. In order to establish standard values for the postnatal timecourse of RBF, 25 healthy neonates were investigated by means of an ultrasonic doppler color flow technique at birth, at 6 and 12 months. The measuraments were done in double by 2 invastigators. The flows were repeatedly recorded at the level of the main renal and the segmentary arteries on both kidneys over 3-4 sistolic-diastolic cycles during an examination time of approx.30 min..The measured items were:
(+) A maxiinum,B minimum values over the cardiac cycle Our results show that:normal values for infants are often in the pathological range for adults, the postnatal decrease of all indexes significantly correlates with postnatal age, the RI correlates the best with postnatal age and may be the most sensitive predictor of pathological changes.
