Abstract :Clinical and serum biochemical markers were utilized to assess the clinical efficacy of routinely used preanaesthetics and induction agents in rabbits. Eight healthy rabbits insert ignore into journalissuearticles values(3.0-3.5kg); of either sex were randomly assigned to one of two groups: XK insert ignore into journalissuearticles values(Xylazine-ketamine); or XFK insert ignore into journalissuearticles values(Xylazine–fentanyl–ketamine);. Intramuscular injections of xylazine insert ignore into journalissuearticles values(5 mg/kg);, ketamine insert ignore into journalissuearticles values(35 mg/kg);, and fentanyl insert ignore into journalissuearticles values(0.02 mg/kg); were given to rabbits. Clinical parameters insert ignore into journalissuearticles values(rectal temperature, heart rate, and respiratory rate);, as well as reflexes insert ignore into journalissuearticles values(righting reflex, palpebral reflex, and pedal reflex);, were measured before and after anaesthetic injection at 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 minutes. Blood samples were also taken before anaesthesia and 30 minutes following induction. An autoanalyzer was used to examine serum biochemical parameters. In the XFK group, we observed that rectal temperature increased considerably insert ignore into journalissuearticles values(P<0.05); at 20 and 30 minutes after induction and then gradually fell to preanaesthetic control values. During the anaesthetic phase, both groups\` heart rates and respiration rates reduced significantly. In XK-injected rabbits, the return of righting reflexes was delayed. Surgical anaesthesia lasted much longer in the animals of XK groups. During surgical anaesthesia, the values of albumin, cholesterol, phosphorus, HDL, and LDL were significantly increased insert ignore into journalissuearticles values(P<0.05); after administration of XK, whereas the values of total protein, globulin, cholesterol, triglyceride, creatinine, HDL, potassium, and chloride were significantly decreased insert ignore into journalissuearticles values(P<0.05);. The XK combination provided sufficient anaesthesia for rabbits, as evidenced by a prolonged anaesthetic period, and good cardiovascular and other clinical indices.
