Tramadol via epidural em cães submetidos à substituição do ligamento cruzado cranial

Ten dogs were submitted to an experimental replacement of the cranial cruciate ligament and received epidural tramadol (1mg/kg) as a trans and post-operative analgesic technique. Cardiovascular and respiratory functions, halothane consumption and post-operative analgesia were evaluated. Cardiovascular and respiratory stability, suitable analgesia during and after the surgery as well as the possibility of reducing the inhalant analgesic consumption were observed. Epidural tramadol is effective as an adjuvant anesthetic in dogs submitted to cranial cruciate ligament replacement.
