Effects of dexamethasone on foetal Doppler flow velocimetry.

In conclusion, Dexamethasone administration affected only the middle cerebral artery pulsatility index before 34 weeks of gestation.IMPACT STATEMENTWhat is already known on this subject? Preterm births account for 75% of neonatal morbidity and pulmonary dysfunction plays an important role on such morbidities. Also, neonates born after an elective CS have significantly higher rates of respiratory morbidity and neonatal intensive care unit admission. Corticosteroids are wildly used to improve neonatal outcome in women who have expected preterm labour and before an elective CS.What do the results of this study add? Dexamethasone affected blood distribution of foetal brain only before 34 weeks of gestation that had been proved by changes of foetal middle cerebral artery pulsatility index without affecting other Doppler parameters of both groups. With the improvement of foetal respiratory outcome in both groups.What are the implications of these finding for clinical practice and/or further research? Maternal Dexamethasone injection is recommended for mothers at risk of preterm labour, especially if delivery is expected within six days and mothers who will undergo elective CS before completion of 39 weeks of gestation, in terms of improving neonatal respiratory functions and decreasing the possibility of admission to neonatal intensive care unit for transient tachypnoea of the newborn.
