Abstract/OtherAbstract:
Hemodynamics is an area of neonatology that is marked more by what we do not know than what we do. What is clear is that it is much more complex than just measuring blood pressure (BP). Early postnatal preterm hemodynamic pathophysiology is characterized by low systemic blood flow (SBF), possibly relating to a mix of afterload compromise, left-to-right shunting through the unconstricted ductus and to the circulatory effects of ventilation. After approximately 24 h of age, vasodilatation seems to be the dominant pathology. In the face of this complexity, a one-size-fits-all approach to treatment that will be applicable in a large clinical trial may prove elusive. The possibility of using a measure of both BP and SBF to target an appropriate treatment needs to be explored.
