Preterm infants are at higher risk of adverse neurodevelopmental outcomes.Inadequate cerebral oxygen delivery resulting from poor cardiovascular function is likely to be a significant contributor to preterm brain injury. In this context, improved support of cardiovascular function is integral to improving preterm outcomes. Many of the treatments used to support preterm cardiovascular function are based on adult physiology and may not be appropriate for the unique physiology of the pre-How to cite this article: Lingwood BE, Eiby YA, Bjorkman ST, Miller SM, Wright IMR.
