Comparative Clinical and Serum Biochemical Evaluation of Two Intramuscular Anaesthetic Combinations (Diazepam/Ketamine and Diazepam/Fentanyl/Ketamine) in Rabbits

Abstract

The clinical efficacy and safety of preanaesthetics and induction agents were examined and compared on the basis of clinical and serum biochemical indicators in rabbits. Eight apparently healthy rabbits (3.0-3.5kg) of either sex were arbitrarily allocated into two groups: Group DK (diazepam-ketamine) and Group DFK (diazepam-fentanyl- ketamine). Rabbits were received intramuscular diazepam (5mg/kg), fentanyl (0.02 mg/kg) and ketamine (35 mg/kg). Data on clinical parameters (rectal temperature, heart rate and respiratory rate) and reflexes (righting reflex, palpebral reflex and pedal reflex) were evaluated before and at 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 minutes after injection of anaesthetics. Blood samples were aspirated prior to anaesthesia and 30 minutes following induction. Serum Albumin, Globulin, Cholesterol, Triglyceride, Total Protein, High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), Creatinine, Calcium, Phosphorus, Sodium, Potassium and Chlorine were evaluated through semiautomatic biochemistry analyzer. In this study, no significant changes in rectal temperature were observed in the animals of group DK during anaesthesia. During anaesthetic cascade, heart rates and respiration rates in both the groups were reduced significantly (P< 0.05). In DFK-injected rabbits, the return of righting and palpebral reflexes were delayed. The DFK groups had considerably (P< 0.05) longer surgical anaesthesia than the DK groups. In terms of serum biochemistry, DK-treated rabbits had significantly lower total protein, globulin, creatinine, HDL, sodium, and potassium concentrations (P< 0.05). Total protein, cholesterol, HDL, and potassium levels decreased significantly (P

A Rabbit Clinical Trial of Xylazine-Ketamine vs. Fentanyl-Ketamine for General Anesthesia

“…In comparison to fentanylketamine anesthesia, the current study demonstrated that xylazine-ketamine anesthesia produced a longer duration of anesthesia and a more seamless recovery. The outcomes of the xylazine-ketamine anesthesia were consistent with the previously published research on sheep [21] and chicks [22,23], as well as rabbits [24, 25,26].…”

Anesthesia Applications In Experimental Neurological Disease Modeling

“…Ketamine and xylazine can be injected simultaneously in rats and mice, and this procedure is slightly different in rabbits (Table 1). First xylazine (5 mg/kg) injection is administered IM, and 10 minutes later ketamine (30 mg/kg) is administered IM in rabbits (12,13). Locally administered bupivacaine (0.25% solution) and lidocaine (1% solution) are local anesthetics and can be used for short procedures in the incision area in mice and rats.…”
