Central blood flow (CBF) was estimated by an intravenous 133-xenon technique in six preterm infants before and after administration of indomethacin for closure of patent ductus arteriosus. CBF fell in all infants (range 12%-40%), the mean fall was 24% (P less than 0.005). Though none of the infants
## Abstract Doppler ultrasound was used to study ophthalmic and middle cerebral artery flow velocities at different ambient lighting conditions in 28 preterm infants in the first week of life. We found significant increases of ophthalmic and middle cerebral artery blood flow velocities when ambient
