Background:Antioxidants located in both the hydrophilic and lipophilic compartments of plasma act as a defencesystem against reactive oxygen species (ROS). Excessive production of ROS during anaesthesia affects theantioxidant capacity of plasma and may result in oxidative stress. The aim of this study was to evaluate theantioxidant capacity of lipid- (ACL) and water-soluble (ACW) antioxidants in client-owned dogs diagnosed withperiodontal disease and early-stage myxomatous mitral valve degeneration (MMVD) and anaesthetised for a dentalprocedure with propofol and sevoflurane or with propofol only.Results:Dogs with MMVD were anaesthetised with propofol and sevoflurane (MMVD/PS,n= 8) or with propofolonly (MMVD/P,n= 10). Dogs with no evidence of MMVD (PS,n= 12) were anaesthetised with propofol andsevoflurane. Blood samples for determination of ACL and ACW were collected before and 5 min, 60 min and 6 hafter induction to anaesthesia. In MMVD/PS dogs, ACL was significantly higher at all sampling times whencompared to PS dogs. Compared to basal values, only anaesthesia maintained with propofol significantly increasedACL at 60 min in dogs with MMVD. In MMVD/P dogs, ACW increased after induction to anaesthesia and remainedelevated up to 6 h after anaesthesia. Compared to basal values, anaesthesia maintained with sevofluranesignificantly increased ACW only at 60 min in both dogs with and without MMVD. The only difference betweenpropofol and propofol/sevoflurane anaesthesia in dogs with MMVD was significantly higher ACW at 60 min afterinduction to anaesthesia in the propofol group.Conclusions:Regarding antioxidant capacity, propofol could be a better choice than sevoflurane for anaesthesia ofdogs with early-stage MMVD, although further studies are necessary to clarify the advantage of this antioxidantcapacity.
