Animal studies of neonatal hypothermic neuroprotection have translated well in to practice

The discovery that mild, induced hypothermia can improve neurological recovery after global moderate to severe hypoxia-ischemia has been a dramatic validation of the strong foundation of preclinical studies that informed current protocols. The major challenge is to find ways to further improve outcomes. As discussed in this review, the findings from large clinical trials of extended cooling are highly concordant with recent animal studies. These findings support the use of precise, carefully selected animal models to refine our strategies to protect babies with moderate to severe encephalopathy before instigating further large trials.
