Abstract：Objective: To observe the feature of cerebral blood flow infusion in early preterm infants. Methods: The Vs, Vd, Vm, S?蛐D and RI were recorded in 68 preterm infants(group A: weight≥1 500 g, group B: weight<1 500 g) and 35 healthy term neonates. The measurement above middle cerebral artery(MCA), lenticulostriate artery(LSA), the terminal artery of lenticulostriate artery(LSAt) was performed by high-frequency color Doppler ultrasound and E-flow within 72 hours after birth. Result: The Vs, Vd, Vm of MCA in preterm infants were lower than that in healthy term neonates obviously(all P<0．05), and the Vs, Vm of MCA of group B were lower than group A, too; while S/D and RI of MCA were not different among the three groups(P>0．05)． The Vs, Vd, Vm, S/D and RI of LSA and LSAt in preterm infants were all lower than that in healthy term neonates(P<0．01). And all the parameters of group B were lower than group A except S/D. Conclusion: The monitoring of multistage brain blood vessel by high-frequency color Doppler combined with E-flow can reflect the basic cerebral blood flow infusion more sensitively and it is valuable to predict the change of cerebral blood flow dynamic in the brain damage of preterm infants.
