Abstract
VCBF (cm/sec) was evaluated by transcranial Doppler Ultravelocimetry of the Galenvein in 5 Groups of newborns of different Gestational Ages (GA:w), Birth Weights (BW:g) and Postnatal Ages (PNA: d):Croup 1), 11 infants, CA=32.9±1.9, BW=1975±288, PNA=1-4;Group 2), 13 infants, GA=32.8±2, BW=1961±524, PNA=5-14;Group 3), 7 infants, CA=31.4 ±2.6, BW=1489±343, PNA=15-30;Group 4), 18 infants, GA=39.3±0.9, BW=3401 ±369, PNA=1-4;Group 5), 8 infants with RDS treated with Continuous Positive Airway Pressure (CPAP), GA-31.5±2, BW=1621±123, PMA=2-14. VCBF was GA and PNA dependent, i.e. it increased significantly with both GA and PNA in the first 4 Groups (p 0.05). (See Table). In infants of Group 5) VCBF decreased significantly (p 0.01) with increasing CPAP by approximately 1 cm/sec per cm H2O CPAP increment. The present study provides normal values of VCBF velocity in the newborn and suggests that monitoring VCBF in infants with RDS could provide useful informations on the possible interferences of excessive CPAP on the cerebral circulation.
