Abstract

Background. The aim of our study was to evaluate the hemodynamic response to acute maternal hyperoxygenation (O 2 test) in a group of growth retarded fetuses with absence or reversal of end-diastolic velocity (AREDV) in the umbilical artery (UA) and to correlate this response to a series of feto-placental velocimetric parameters and clinical variables. Method, In 25 singleton pregnancies, feto-maternal Doppler velocimetry was performed before and after acute maternal hyperoxygenation. Results, Ten fetuses (40%) exhibited an increase of middle cerebral artery Pulsatility Index (PI) > 20% after O 2 (Responders), while in 15 fetuses PI did not change relevantly (Non-responders). Non-responder fetuses showed a higher prevalence of reverse flow in umbilical artery (6/15 vs 0/10; p
