In this study a team of researchers – led by M.E. Hubner – compared the outcomes of babies born normally and by Caesarean section and how the use of antenatal steroids affected their health. 4,386 babies were included in the study which looked back at records compiled between 2001 and 2011. 45.8% of them were delivered normally while the rest were delivered via a Caesarean section. Babies delivered normally received fewer steroids, had a lower gestational age and Apgar scores and a lower incidence of survival and a higher incidence of severe intraventricular haemorrhage (sIVH). Babies whose mothers had been given antenatal steroids were more likely to survive regardless of whether they were born normally or via Caesarean section. For very premature babies (24-25 weeks) increased survival and sIVH-free survival were more likely in babies born via a Caesarean section.
