Avaliação algimétrica por estímulo nociceptivo térmico e pressórico em cães pré-tratados com levomepromazina, midazolam e quetamina associados ou não ao butorfanol ou buprenorfina

Abstract: Avaliação algimétrica por estímulo nociceptivo térmico e pressórico em cães pré-tratados com levomepromazina, midazolam e quetamina Acta Cirúrgica Brasileira -Vol 20 (1) 2005 -39 RESUMOObjetivo: Quantificar a dor em cães sob anestesia dissociativa através de estímulo térmico e pressórico e o período hábil de dois analgésicos opióides. Métodos: Empregaram-se 30 cães alocados em três grupos (n=10), onde os animais de GI receberam levomepromazina e midazolam associado na mesma seringa à quetamina. Os animais… Show more

“…When the recovery period of animals treated with methotrimeprazine-midazolam-ketamine through intramuscular and intravenous via were compared, it was observed a reduction in the same period when the second via was utilized. Santos 11 describes an anesthetic recovery of 76 minutes for dogs treated with the combination above mentioned, via intramuscular, and 38 minutes with continuous infusion, event also reported by Rosa and Massone 21 . The decrease in CF in G3 was considered due, not only to the methotrimeprazine use in the pre-anesthetic medication, but also and mainly to the use of xylazine.…”

“…In both groups the cardiac frequency (CF) behavior was similar showing a slight decrease, but within the physiological limits, as reported for pre-treated dogs with intravenous buprenorphine 28 leading to. This reduction can be associated to the depressing effects of methotrimeprazine 29 by a CF decrease in pre-treated dogs with methotrimeprazine and treated with a-2 agonists, probably due to the increasing tachycardia effect caused by ketamine through the direct synaptic stimulation by elevation of circulating norepinephrine. The increase in the membrane cells permeability excites the conductors by the action of norepinephrine 30,31,32 favoring the passage of Na+, making the fibers more excitable and, as a result, avoiding or increasing bradycardia.…”
