Evaluation of the effects of different doses of etomidate pharmacology contention on Phrynops geoffroanus SCHWEIGGER, 1812 (Testudines, Chelidae)

Abstract

The objective of this study was to evaluate the effects of different anesthetic protocols in Phyrynops geoffroanus etomidate. We used 30 Phrynops geoffraonus (turtle-de-beard), Uberabinha from the river, Uberlândia, MG, clinically healthy, 17 males and 13 females, and weight ranging from 0.400 to 3.550 kilograms. The survey was conducted in November 2006, where climatic conditions were warm and humid climate. The tortoises were divided into groups of ten anesthetized with etomidate different protocols: group 1 (G1) received 1.0 mg / kg IV, Group 2 (G2) received 1.5 mg / kg IV group 3 (G3) received 3.0 mg / kg IV. The administration of the anesthetic was made by direct cervical spine within. Parameters were observed anesthetic locomotion, muscle relaxation, response to stimuli in the thoracic limbs and pelvinos, handling and heartbeat, at 0, 5, 10, 20, 30, 40, 45, 60, 90, 120, 150 and 180 minutes after the injections. It is concluded that etomidate at a dose of 3.0 mg / kg IV, although insurance was not effective for surgical anesthesia Phrynops geoffroanus It is suitable for occasions that require a satisfactory pharmacological restraint, with optimum temperature, and that doses of 1.0 mg / kg IV and 1.5 mg / kg IV is indicated in situations that require sedation satisfactory Phrynops geoffroanus as clinical procedures and collection of biological samples at optimum temperature.
