| Outline of Final Research Achievements |
Using the myocardial ischemia and reperfusion model in vivo rabbit, we studied whether remifentanil, inhalation anesthetic isoflurane and remifentanil and isoflurane combination decreased myocardial infarction size as compared with the control group. As a result, remifentanil, the isoflurane significantly showed myocardial protection effect, respectively. In addition, the combination of both showed myocardial protection effect, but there was no significant difference between groups. NO inhibitor made myocardial protection effect disappear from different experiment. Therefore, it was suggested that NO was involved in the mechanism of action. This study showed that combination of commonly used remifentanil and inhalation anesthetic showed myocardial protection effect and this study elucidated a part of the mechanism of this action.
