Abstract
This study was performed to compare two opioid drugs with isoflurane and to determine the difference between isoflurane/remifentanil anesthesia and isoflurane/fentanyl anesthesia in terms of the anesthetic effects in beagle dogs. Isoflurane was maintained at 0.5 MAC, and the opioid drug was administered as a constant rate infusion. The anesthesia was maintained for 2 hours, and isoflurane and opioid drugs were discontinued 2 hours later. After discontinuing the anesthetics, the extremity movement time, eye global positioning time, gag reflex time, head up time, sternal recumbency time, standing time, walking time and complete recovery times were recorded for each dog. Both of the studied anesthetic protocols were suitable in beagle dogs because the anesthetic status was well maintained until the end of the procedure, and rapid recovery times were demonstrated in this experiment. And this study shows that the isoflurane/remifentanil group was more reliable than the isoflurane/fentanyl group because the recovery time CV was lower. Therefore, isoflurane/remifentanil combination anesthesia could be a better choice than isoflurane/fentanyl anesthesia if the patient is severely ill and stable recovery time is needed.
