ANDRADE, Edgard. Neonatal hypoxic ischemic encephalopathy: Progress and new treatments according to the pathophysiological basis of the injury. Medicina (B. Aires) [online]. 2023, vol.83, suppl.4, pp.25-30. ISSN 0025-7680.

Neonatal hypoxic ischemic encephalopathy (HIE) is a type of injury caused by lack of oxygen in the brain during the neonatal period. It is a clinical syndrome clearly rec ognizable in term and premature newborns secondary to asphyxia at the time of delivery. HIE is estimated to occur at a frequency of 1-3 for each 1000 alive newborns per year in developed countries. In countries of low or medium income, the incidence is up to 10-20 times higher, equivalent to 1-8 alive newborns per each 1000. The social and economic impact has been estimated near US$ 50.2 million per year of life adjusted to disability. At the same time, it is estimated in 7, the number of patients needed to treat with corporal cooling therapy (CCT) to prevent one case of death or se vere disability. The etiology is multifactorial and includes prenatal, perinatal and postnatal factors. The diagnosis is based in the inability to support spontaneous breath at the time of delivery requiring assisted ventilation, Apgar less than 5 at 5 and 10 minutes, altered level of consciousness, neonatal reflexes and muscle tone. This article is a review of the stablished and emergent therapeutic strategies based on the pathophysiological disease process.
