Efeitos do Propofol na dose de 20 mg/kg via intracelomática em rãs touro Lithobates Catesbeianus Shaw, 1802

Abstract

This work was executed in order to evaluate the effects of Propofol anesthetic in bull frogs amphibians (Lithobates catesbeianus). It was used ten exemplares of species, with average weight of 157,5 grams, staying, at the moment of the experiment, at ambient temperature and humidity of 25,6ºC and 59,70%, respectively. Anesthetic was applied with Propofol 20 mg/kg/IC in the ventral abdomen. The heart frequency of the animals was monitored with the Electronic and Vascular Doppler. During transanesthetic period, it was used subjective scores in relation of the stipulate parameters: locomotion, muscle relaxation, manipulation, painful stimulus at thoracic and pelvic members, cardiac frequency, loss the reaction straightening postural (RSP) and return of the RSP or ambulation. All the animals maintained response to the painful stimuli in the limbs. This drug demonstrated being ideal for the execution of clinical procedure, biology sample collection, contention and assistant in balanced anesthesy on that species, because promoted muscle relaxation and facility of manipulation, with high security margin in the return of the sedation, no presentation analgesic result. There wasn t any significant decrease at the cardiac beats of these animals.
