Despite the progress in perinatal care, perinatal asphyxia (PA) remains a significant problem in neonatology. The development of therapeutic hypothermia (TH) has improved the prognosis, but it still remains uncertain in hypoxic neonates. The evaluation of the severity of ischemia/hypoxia after birth is crucial to the choice of treatment, and with accurate long-term prognosis, appropriate further patient care can be planned. This article presents various methods for the preliminary assessment of brain damage and prognosis in newborns with PA treated with TH. The importance of assessing the neurological condition and the usefulness of laboratory and electrophysiological testing and imaging are discussed. New methods are also noted, which are at the stage of clinical trials. A combination of the prognostic tests presented in this article can provide greater prognostic accuracy for predicting long-term neurological outcomes in infants with hypoxic-ischemic encephalopathy (HIE) undergoing TH than either of these tests independently. Acknowledging the limitations of individual tools in certain clinical situations and the integration of the information available from multiple biomarkers may help improve the accuracy of prognostication.
