| Outline of Final Research Achievements |
In cardiac surgery of children with anomaly of the aortic arch, brain blood is supplied by a particular method, called selective cerebral perfusion under using cardiopulmonary bypass. We devised a simple selective cerebral perfusion model on rats. To develop an adequate procedure for children with cyanosis, we conducted experiment on selective cerebral perfusion in juvenile rats bred under hypoxic environment. Neural damage of brain was investigated with a special microscopic examination that detected early neural injury. Brain damage caused by the selective cerebral perfusion was more serious in juvenile rats bred under hypoxic environment than in normal rats. So, we should be careful about the selective cerebral perfusion of children with cyanosis.
