Avaliação de parâmetros transoperatórios comparando o uso da morfina via epidural com o uso de infusão de fentanil e Infusão de fentanil associado à lidocaína e cetamina em cães submetidos a neurocirurgias: estudo retrospectivo

Abstract

The neurosurgeries has become more frequent on veterinary hospitals, however there are some questions regarding anesthetics protocols and analgesic techniques. Thus, the patient’s analgesia and stability are of fundamental importance for the trans operatory moment and to favor his adequate recovery. The majority of the patients are from canine species and the most commom procedure is hemilaminectomy. It was used informations from anesthetics files from animals, which surgeries were performed on the Federal University of Santa Maria on the period of January 2016 untill 2017. Thus, it was aimed to evaluate parameters, such as: cardiac frequency (FC), respiratory frequency (f), blood oxigen saturation (SpO2), mean artery pressure (PAM), temperature and end tidal CO2 (EtCO2) of anesthetized dogs with morphine admnistered by epidural route and compare with the same parameters from dogs anesthetized with fentanil infusion, or association with fentanil, lidocaine and ketamine (FLK) in hemilaminectomies. It was observed that the protocol using morphine provoked significantly body temperature reduction than the protocols using only fentanil or FLK, but the other parameters didn’t show significative variations.
