Cortisol sérico e glicemia em cadelas tratadas com tramadol e submetidas à ovário-histerectomia

Abstract: O tramadol é um analgésico opióide usado em medicina veterinária, embora existam poucos estudos sobre este fármaco. O objetivo deste trabalho foi avaliar o efeito analgésico promovido pela administração do tramadol, mensurando o cortisol sérico e a glicemia de cadelas. Para isso, foram utilizadas 15 fêmeas, submetidas a ovário-histerectomia sob anestesia geral com isofluorano. Os animais foram divididos em três grupos. Grupo 1 (Tep) receberam tramadol pela via epidural (1,0mg kg-1 diluído em água bidestilada a… Show more

“…In the present study, no significant changes in serum levels of glucose and cortisol were seen immediately after anesthetic induction (T4), indicating that animal manipulation, including physical restraint, venipuncture, drug administration, and orotracheal intubation did not interfere with neuroendocrine and metabolic functions, in accordance with observations of Church et al [ 19 ] and Caldeira et al [ 20 ]. Although Yoder and Wolf [ 21 ] reported association between duration of surgery and cortisol levels in postoperative period of dogs that underwent nephrectomy, there was no correlation, in this study, between those parameters, nor did we find an association between duration of surgery and glycemia.…”

“…This allows us to consider that cortisol and glucose increase at the moment of greatest stress during surgery, which can compare with the analgesic action of different drugs (Lacerda & Nunes, 2008). Caldeira et al (2006) considers that serum cortisol and blood glucose are adequate parameters for pain assessment in bitches undergoing OSH. According to Feldman & Nelson (1985), cortisol varies between 0.5 µg/dL and 6.0 µg/dL, equivalent to 13.795 nmol/L and 165.54 nmol/L, respectively; and glucose varies between 70 and 110 mg/dL.…”

“…The efficacy of analgesia with a given drug has been demonstrated in previous studies by physiological changes that indicate pain. Serum cortisol dosing was an interesting addition to this assessment in various studies, since this is a hormone that increases its levels during surgery and postoperative pain (Mastrocinque and Fantoni, 2003;Caldeira et al, 2006). Cortisol levels showed an increase over time during the postoperative period, which can be related to clearance of tramadol and onset of postoperative pain.…”
