Growth deficits in a postnatal day 3 rat model of hypoxic-ischemic brain injury.

The postnatal day (P) 3 rat model of hypoxic-ischemic (HI) brain injury provides valuable information regarding the cellular response to HI injury in a very immature brain. Our present study is the first to examine growth, metabolic, and behavioral outcomes following a P3 HI brain injury. Rats were injured by cauterizing the right common carotid, and exposure to 8% oxygen for 1.
