Effects of sevoflurane and isoflurane on acute myocardial infarction model establishment in mice

Le résumé fourni par la source

The selection of anesthetic drugs in the preparation of an acute myocardial infarction (AMI) model is very important. We specifically focus on various effects of sevoflurane and isoflurane in a murine AMI model, which have not been previously compared. Furthermore, we evaluated success of our AMI model using following methods: echocardiography, TTC staining, and PCR testing. The results show that compared to the isoflurane group, the sevoflurane group mice had shorter anesthetic induction(66.40 ± 2.90S vs. 125.10 ± 6.30S P < 0.0001) and recovery times(28.00 ± 1.07S vs. 56.88 ± 4.14S, P < 0.0001), lower incidence of respiratory depression (0 % vs. 50.00 %, P = 0.0325), and more successful models (93.33 % vs. 60.00 %, P = 0.0801). There were no significant differences in cardiac function, infarction area(49.41 ± 4.18 % vs. 48.66 ± 3.79 %, P = 0.5266), or inflammatory factors in the myocardial infarction area between the two groups. Sevoflurane may therefore be a better choice for the establishment of AMI models in mice.
