RESUMEN
The mortality rate of newborns with severe congenital heart disease (CHD) has significantly decreased over the past few decades. However, many of these children experience neurological impairments, particularly following a hypoxic cardiac arrest. The use of extracorporeal membrane oxygenation (ECMO) has been considered an effective treatment for severe hypoxia in CHD cases. Various clinical studies have examined the use of ECMO for resuscitation after hypoxic cardiac arrest, but the results have been contradictory, showing a significant incidence of both mortality and morbidity in some studies while others report good outcome. In order to investigate the mechanisms behind brain injury associated with extracorporeal circulation, we have developed a neonatal porcine model of hypoxia-induced cardiac arrest followed by veno-arterial ECMO therapy.
