Cerebral electrical impedance was compared with simultaneous estimations of cerebral blood flow (CBF∞ using the Xe clearance technique on 28 occasions in 9 neonates who had changes in Pa and hence presumably cerebral blood flow between measurements. Various indices derived from the impedance waveform which have been reported in the adult to correlate with blood flow were analysed for their relationship with CBF∞ Percentage change of the two variables was calculated and three indices showed a significant correlation using linear regression. They were peak amplitude (ΔZ), ΔZ times heart rate (ΔZ×HR), and backslope projection. The regression equation for the index with the closest correlation was ΔZ×HR=0.57CBF∞plus;3.4 with r=0.68 (p=0.003) an...
