| Outline of Final Research Achievements |
In these studies, we found that combining the cerebral blood volume (CBV) with amplitude-integrated EEG (aEEG) is a more effective guide to control hypoxic/ischemic (HI) insult in a newborn piglet model than aEEG alone, to produce a consistent degree of survivable neuropathological damage. Next, we found that an early CBV increase and longer low-ampitude EEG after insult indicates severe brain injury. Finally, we revealed that Edaravone (a free radical scavenger) reduced histologic neuronal damage related to HI loading in our piglet HI model. However, we also found the histopathological damage, especially kidney tissue. We have to consider the systemic impact by Edaravone.
