Contenção farmacológica de ouriço-cacheiro (Coendou prehensilis, Linnaeus, 1758), com protocolos calculados por extrapolação alométrica interespecífica

Abstract

The prehensile-tailed porcupine (Coendou prehensilis) is a neotropical rodent that has your body covered by thorns, needs to be restraint by pharmacological means for performing certain medical procedures and management, due to defensive behavioral characteristics. Two protocols were performed (tiletamine and zolazepam, atropine, xylazine and tiletamine and zolazepam, atropine and detomidine) for chemical restraint, in order to allow the accomplishment of procedures of which included physical examination, marking, blood sampling, bone marrow harvest and other minimally invasive procedures of moderate duration in Coendou prehensilis of captivity. After verification of the weights of each animal, the individual dose of each of the associations was calculated through interspecific allometric scaling. We evaluated the frequency of heart and respiratory rate, rectal temperature, systolic blood pressure, diastolic blood pressure and the noninvasive mean pressure, and partial oxygen saturation in the blood. The proposed methods proved to be fully adequate for the pharmacological restraint of Coendou preensilis that need to be submitted to medically painful or uncomfortable procedures, such as physical examination and collection of blood and bone marrow, not being indicated for surgical procedures.
