Evaluation Of The Effects Of Two Anaesthetic Protocols On Oxidative Status And Dna Damage In Red-Eared Sliders (Trachemys Scripta Elegans) Undergoing Endoscopic Coeliotomy (Jan, 10.1556/004.2020.00058, 2021)

The aim of this study was to assess how red-eared sliders (Trachemys scripta elegans) respond to anaesthesia itself and coelioscopy. For that purpose, the turtles were anaesthetised with ketaminemedetomidine or propofol, and the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione 5-transferase (GST) and the level of malondialdehyde (MDA) were determined by spectrophotometry. The possible genotoxic effects of the anaesthetic agents were estimated by comet assay. A total of 24 turtles were included in this study. The animals were divided into four groups according to the anaesthetic protocol and according to whether endoscopy would be performed. Significantly decreased activities of CAT were found only in the propofol group and in turtles undergoing coelioscopy. Both anaesthetic protocols induced significantly increased MDA levels, while no differences were observed after the intervention. A significant increase in GST activity was detected in turtles after both anaesthetic protocols, but after coelioscopy significant changes in GST activity were found only in the propofol group. However, no differences in SOD activity and no DNA damages were detected in either group. These findings suggest that ketamine medetomidine may be more suitable anaesthetic agents in red-eared sliders than propofol.
