Femoral blood flow in term and premature infants

A specially designed 20-MHz pulsed Doppler velocity meter was used to quantify noninvasively common femoral artery blood flow and blood flow characteristics in 11 normal term and 12 premature infants. Femoral artery mean velocity (vf), blood flow (Q), weight-normalized blood flow (Q/kg) and pulsatil...

Description
Summary:	A specially designed 20-MHz pulsed Doppler velocity meter was used to quantify noninvasively common femoral artery blood flow and blood flow characteristics in 11 normal term and 12 premature infants. Femoral artery mean velocity (vf), blood flow (Q), weight-normalized blood flow (Q/kg) and pulsatility index (PI) were determined for the two groups. Mean values for Q (+/- SD) in the term and preterm infants were 27.3 +/- 10.3 and 23.4 +/- 14.7 (ml X min-1), respectively (P less than 0.1). Mean Q/kg for the premature infants was significantly higher (22.1 +/- 12.8) than that for the term infants (9.1 +/- 4.2), P less than 0.005. This study demonstrates differences between the pulsatile blood flow and velocity characteristics of the femoral arteries of premature and of full-term infants.
