Abstract

New knowledge of the pathophysiology and evolution of hypoxic-ischemic brain injuries has made feasible interventions to improve clinical outcomes for newborns surviving birth asphyxia. Brain injury following hypoxic-ischemic insult is a complex process evolving over hours to days, which provides a unique window of opportunity for neuroprotective treatment interventions. The specific pathologic processes preceding the onset of irreversible cerebral injury appear to be a combination of several mechanisms that are variable according to the severity and duration of the insult and to biochemical modifications in the brain. Advances in neuroimaging, brain monitoring techniques, and tissue biomarkers have improved the ability to diagnose, monitor, and care for newborn infants with neonatal encephalopathy, as well as to predict their outcome. The role of oxidative stress in newborn morbidity with respect to the higher risk of free radical damage in these babies is growing. However, challenges remain in early identification of infants at risk for neonatal encephalopathy, determination of timing and extent of hypoxic-ischemic brain injury, as well as optimal management and treatment duration. Potential neuroprotective strategies targeti...Continue Reading
