Comparação analgésica pós operatória do Tramadol ou morfina epidural em ovinos submetidos à cesariana

Abstract

Sense is the ability to feel, which encompasses all vertebrate animals. Production animals are scarcely attracted to welfare. There is always the financial barrier. Beyond the culture that you do not feel pain. Ruminants, particularly sheep, are relatively stoic beings, showing no obvious signs of anguish and pain, yet they are susceptible to it. The present work aims to make a brief review about pain and its evaluation. It also brings the evaluation of postoperative pain in sheep submitted to cesarean section, with the comparison of two analgesic protocols. Tramadol hydrochloride (2mg.kg-1, epidural route, GT), or morphine sulfate (0,1mg.kg-1, epidural, GM) was used to evaluate the analgesic efficiency of the protocols, as well as analgesia obtained. An adaptation of the UNESP Botucatu's One-Dimensional Scale for Post-Operative Pain Evaluation in Bovine was used. There was satisfactory analgesia up to 8 hours in both groups. There were no significant physiological changes. However, there was a greater reduction of ruminal and respiratory movements in GT. Scale adaptation was satisfactory in the evaluation of pain. The paper is inserted in this monograph as an article form, which will be submitted to the journal PubVet, as a requirement to obtain the title of specialist in veterinary anesthesiology
