The blood flow velocity of the internal jugular vein (38 infants), internal cerebral vein (28 infants), and straight sinus (18 infants) in a group of clinically stable neonates and young infants (body weight 1060-3750 g, age 1-86 d, gestational age 28-41 wk) is specified. The time mean of maximum velocity (Vma) of internal jugular vein was 8.4 +/- 4.7 cm/s, of internal cerebral vein 5.5 +/- 1.6 cm/s, and of straight sinus 12.6 +/- 7.8 cm/s. While the variability between infants was high, the reproducibility of the method was in the range of 4.4-10.2% for Vma. This compares well with studies on cerebral arteries and offers a noninvasive approach to the study of the venous cerebral hemodynamics in neonates undergoing intensive care. | lld:pubmed |
