Melatonin and/or erythropoietin combined with hypothermia in a piglet model of perinatal asphyxia

As therapeutic hypothermia is only partially protective for neonatal encephalopathy, safe and effective adjunct therapies are urgently needed. Melatonin and erythropoietin show promise as safe and effective neuroprotective therapies. We hypothesized that melatonin and erythropoietin individually augment 12-h hypothermia (double therapies) and hypothermia + melatonin + erythropoietin (triple therapy) leads to optimal brain protection. Following carotid artery occlusion and hypoxia, 49 male piglets (
As therapeutic hypothermia is partially protective in neonatal encephalopathy, adjunct therapies are required. In a piglet model of perinatal asphyxia, Pang et al. report that melatonin and erythropoietin are safe and individually augment cooling through different mechanisms. Staggered rather than concomitant dosing may be optimal for brain protection.
