Histopathological and Serum Enzyme Changes of Propofol Combined with Pre-Anesthetic Agents in Domestic Pigeons (Columba livia)

Abstract

Objective- Because of the several differences between avian and mammalian physiology and anatomy, avian anesthesia requires to be more attentive. The aim of this study was to determine a safe injectable anesthetic agent that had more compatibility with the avian features. Design- Experimental study Animals- Twelve male pigeons Procedure- The pigeons weighing 302±35 g (mean±SD) were divided into two groups (n=6). In group 1, midazolam (6 mg/kg,-IM) and in group 2, metamizole (500 mg/kg,-IM) were administrated as the pre-anesthetic agents and thereafter, propofol (8 mg/kg,-IV) was injected as the main anesthetic drug in both groups. The serum enzymatic changes were analyzed before and 1 hour after the last injection. Histopathological examinations of the liver and kidneys were also evaluated in terms of possible damages to the tissue. Results- The results of blood biochemistry evaluation in group 1 showed significant changes in the levels of AST and LDH before and after the injections (p 0.05). Conclusion and clinical relevance- Based on the results, metamizole and propofol combination showed that is safer than midazolam and propofol in terms of blood biochemical and histopathological evaluations and is more compatible with pigeons.
