Effects of an anesthetic mixture of medetomidine, midazolam, and butorphanol and antagonism by atipamezole in rabbits.

We examined the antagonistic effects of ATI by intramuscular (IM) or intravenous (IV) injection in rabbits. We used the anesthetic score to measure surgical anesthetic duration and recovery time from anesthesia. During the experiments, we measured heart rate, respiratory rate, O2-saturation, and blood pressure. We found there were no significant differences in anesthetic duration and recovery time between MMB and KX. There were no significant differences in heart rate after administration of MMB or KX. Systolic blood pressure at 10 min after administration of MMB was higher than that of KX. The antagonistic effect of ATI by IV injection worked faster than that by IM injection. Overall, MMB is a useful drug that can induce similar anesthetic effects to KX and has an antagonist of ATI that makes rabbits quickly recover from anesthesia. These results may contribute to the welfare of laboratory animals, especially rabbits. PMID: 31092746 [PubMed - as supplied by publisher]
