Resumen
This study aimed to evaluate the cerebral blood flow of full term small-for-gestational age newborns, using cranial ultrasound Doppler at birth. This study was performed at CAISM/UNICAMP (Tertiary Health Center for Women). Sixty term newborns were selected and divided in two groups: appropriate-for-gestational age (AGA) (36 neonates) and small-for-gestational age (SGA) (24 neonates). Cranial ultrasound Doppler evaluation was performed on both groups, between 24 and 48 hours after birth. Cerebral blood flow velocity (CBFV) was lower in the small-for-gestational age group, in the anterior cerebral artery (ACA). Doppler measurements were different statistically between the groups only for values related to peak systolic flow velocity (PSFV) and mean flow velocity (MFV) in the ACA. There was no significant difference for any evaluated parameters of flow velocity in the middle cerebral artery (MCA). It was concluded that SGA newborns showed PSFV and MFV significantly reduced only in the ACA. Weight/gestational age, neonatal polycythemia and mean arterial blood pressure values were statistically related to MFV in the ACA. In presence of fetal suffering, mean arterial blood pressure values and smoking in the pregnancy were statistically related to MFV in the MCA. 61 3 B 808 815 Arend, F.B., Christa, E., Heinz, F.R.P.,
