Effect of maternal corticosteroid provision on middle cerebral artery peak systolic velocity readings in the potentially anaemic fetus prior to planned intrauterine transfusion.

This study found no sizeable, generalised effect of corticosteroid administration on MCA-PSV readings in the potentially anaemic fetus. A minority showed substantial shifts where reliance on post-steroid MCA-PSV could have unfavourably altered clinical management. Ultimately, further large-scale research is required before we can discount the potential impact of steroids on MCA-PSV values.
