Abstract
Many drugs or additives have been tried as adjuvants in the blocking of nerve blocks with local anesthetics, and it is aimed to increase the duration of action and analgesia quality of local anesthetics in this way. In this study, we aimed to see the adjuvant efficacy of Dexmedetomidine [Dex] added to bupivacaine and its effect on analgesia and histopathological effects in rabbits by administering sevoflurane anesthesia. Twenty-four rabbits were randomly allocated to 3 groups; Group S: sham [0.5 ml saline], Group B: perineural bupivacaine [0.5 mg/kg] [0.5 ml] and Group BD: perineural bupivacaine [0.5 mg/kg] combined with Dex [20 µr/kg] [0.5 ml]. Analgesia measurement was evaluated by hotplate test, the paw withdrawal response was performed for sensorial and motor blockades also were recorded at baseline, 30, 60, 90, and 120 min after drug administration. Dissected nerve tissue was also examined for histopathologic evaluation. In the hot-plate test applied for the measurement of acute thermal pain; when compared to Group S, significant prolongation was found in Group B and Group BD at 0, 30, 60, 90, and 120 minutes [p
