Hypoxic-ischemic encephalopathy (HIE) can have both transient and long-lasting effects on the neonate, including neurologic, renal, cardiac, hepatic, and hematologic. Both the disease process and the treatment option of therapeutic hypothermia can result in hemodynamic instability. Understanding the effects of HIE on the neonatal myocardium, pulmonary vascular bed, and the cardiac dysfunction that can occur is key to managing infants with HIE. This article focuses on causes of hemodynamic instability in neonates following perinatal asphyxia and how to recognize hemodynamic compromise. It reviews the underlying pathophysiology and associated management strategies to improve hemodynamics and potentially improve outcomes.
Keywords: cardiovascular status; hemodynamics; hypoxic-ischemic encephalopathy (HIE); neurology.
