Do Rescue ACSs Affect Neurodevelopment? New March 2023 Data.

The Liggins and Howie trial demonstrating the benefit of antenatal corticosteroids (ACSs) on fetal lungs was published in 1972 in the journal Pediatrics. First adopted as weekly injections, ACSs were then found to be associated with decreased birth weights and decreased head circumferences. Hence, weekly administration was abandoned in the late 1990s. But the ACOG/SMFM does still recognize a single repeat dose “based on clinical scenario”, called a rescue dose. Is a rescue dose of steroids associated with altered neurodevelopment in the child? In this episode, we will summarize a brand new study just accepted for publication in the AJOG MFM (the Pink Journal) shedding some light on this question.
