The development of new analgesic techniques represents the possibility of minimizing the risks inherent to anesthetic procedures and also better recovery after the procedure, reflecting directly on the animals welfare. We sought to evaluate the analgesic efficacy promoted by tramadol, lidocaine an ketamine association, administered intravenously under continuous infusion in cats submitted to ovariohysterectomy. 24 cats were segregated in 4 groups, G1- control administered only with physiological solution 0,9% (10ml/kg/hour), G2- received an initial bolus of tramadol (2mg/kg EV), ketamine (1mg/ kg EV) and lidocaine (1mg/kg, IV), followed by continuous infusion of tramadol (2mg/kg /hour), lidocaine (3mg/kg/h) and ketamine (0,6mg/kg/hour) diluted with physiological solution to 0,9% (10ml/kg/hour), G3- Same G2 bolus, with halved continuous infusion and G4- without bolus dose and halved continuous infusion. Was applied a questionnaire related to animals behavior, to assess whether was interference with post-castration life quality. Physiological variables, as heart and breathing rate, temperature, systolic pressure, diastolic and mean, in addition to cortisol and glucose measurements that were made at predetermined times. The G2 showed better results without variables changes during trans-surgical that could suggest the presence of pain, the other groups showed similar behavior, with an increase in the values of some physiological parameters, suggesting painful stimuli, especially in the increase of cortisol levels. It was made subjective evaluation, two to eight hours after the procedure, according to the scale of Brondani pain et al., (2012) G1 had higher scores in T4 (17.5), and G2 the lowest (7.5), confirming that the proposed protocol on the G2 is more successful, even after surgery. Pre- and late postoperative period (180 days after the procedure), assessed by questionnaire, all animals preserves normal behavior for the species, suggesting that surgery contributed to the quality of life and welfare of cats.
