Abstract
This study aimed to examine some physiological parameters including heart rate, respiratory rate, body temperature, blood pressure, and oxygen saturation in dogs that were anesthetized with sevoflurane for sterilization and to examine the associations between these parameters at different times of anesthesia. Thirty-four (34) dogs with body weights between 1.7 and 25kg were pre-anesthetized with zolazepam, tiletamine, medetomidine hydrochloride, and butorphanol, and then they were maintained with sevoflurane. Physiological parameters were recorded at different times during anesthesia. During surgical anesthesia, the heart rates and body temperatures of most dogs were in the physiological range. The respiratory rate, blood pressure, and oxygen saturation varied widely. At the time of the Sevoflurane connection, the heart rate was directly proportional to the breathing rate, and systolic blood pressure was directly proportional to temperature and heart rate. However, these associations were no longer present at 30 minutes and 60 minutes after the sevoflurane connection. At 60 minutes, oxygen saturation was inversely proportional to diastolic though this association was not present at the time of the Sevoflurane connection and at 30 minutes. The results show that sevoflurane maintenance of anesthesia in dogs was safe. Because physiological parameters could vary widely within each dog and during anesthesia, all dogs have to be monitored carefully throughout the surgical process to handle complications that might occur. On the other hand, Sevofulrane might have effects at different degrees on different physiological parameters and this potential characteristic should be investigated in future research.
