Abstract
Partial exchange transfusion (hemodilution) for neonatal polycythemia is performed to improve overall systemic oxygen transport and blood flow to organs.
Material and Methods: Cardiac output, blood flow velocities (BFV) of the internal carotid artery (ICA) and the celiac artery (CA) were measured by pulsed Doppler ultrasound before and after hemodilution in nine neonates (2.3 - 4.4 kg birth weigth, 33 -41 wk gestational age). Blood pressure (oscillometry) and hematocrit (microcentrifuge) were measured.
Results:
There was a significant correlation between Q and Hct (p <.002). Red cell flow in the aorta, in the ICA and in the CA did not change. Correlations between Q and BFV in the ICA were closer than those between Q and BFV in the CA, particularly before hemodilution.
