Abstract
Background: It is well established that therapeutic hypothermia improves outcomes for infants with moderate-severe hypoxic-ischemic encephalopathy (HIE) in high-income counties. However, ∼29% of the infants treated with therapeutic hypothermia still have adverse outcome. Additionally, therapeutic hypothermia is not recommended as a treatment for infants with HIE in low- and middle-income countries. Therefore, there is an urgent need to develop alternative treatments for infants with HIE in low- and middle-income countries, as well as additive treatments to therapeutic hypothermia in high-income countries. Summary: Caffeine is widely used as an agent to prevent apnea in preterm infants, and more recently, it has been investigated as a potential neuroprotective treatment for perinatal hypoxic-ischemic (HI) brain injury, but the preclinical evidence so far has been mixed. Furthermore, there are concerns that caffeine, which is an adenosine receptor antagonist, could abolish the endogenous neuroprotective effects of adenosine, during and after HI. Key Messages: Further studies using caffeine particularly in large animal translational models of HI brain injury are required to establish the safety and efficacy of caffeine for HIE before conducting large randomized controlled trials.
