Evaluation of the use of the combination of propofol and midazolam in the chemical restraint and anesthesia of the turtle-de-beard Phrynops geoffroanus Schweigger, 1812 (Testudines, Chelidae)

Abstract

The objective of this research was to determine a protocol for effective and safe pharmacological restraint (Phrynops geoffroanusi), with average weight of 1.9 ± 0.77 kg, clinically healthy, 02 males and 18 females, capturing in Uberabinha river in the city of Uberlândia - MG under license M ° 032/2006 IBAMA-RAN, were housed in a tank with running water and water heaters with an average temperature of 27 ° C. the turtles were divided into two groups of 10 animals: G1 - midazolam (2.0 mg / kg IM) and propofol (5.0 mg / kg IV) and G2 - midazolam (2.0 mg / kg IM) and propofol 2.5 mg / kg IV). Midazolam was administered in the left forelimb and propofol was injected directly in the cervical vertebral sinus. There was the anesthetic parameters of movement, muscular relaxation, in response to stimuli forelimbs and tail, ease of handling and heart rate, at 0 and 5, 10, 20, 30, 45, 60, 90, 120, 150 and 180 minutes after the injections. There was no statistically significant between two groups, so this protocol is not indicated for surgical procedures in Phrynops geoffroanus.
