The number of wandering animals in large urban centers is increasing, and the cat population is quite significant. Pre-pubertal sterilization promotes early reproductive failure of the animal; reduces the development of pathologies related to the reproductive tract, in addition of other advantages. However, anesthesia in prepubertal animals is still a challenge and the usage of opioids in those patient has been questioned due to the occurrence of hypotension in some cases. Accordingly, it is necessary further studies to verify the consequences of the use of opioids in these animals. Therefore, the present study had as objective to evaluate the effectiveness of the use of Tramadol in prepubescent queens submitted to ovariohisterectomy. Eight females of the feline species, aged between two and four months, were used. The queens were randomly divided into two groups (Control group and Tramadol group), consisting of four animals each. During the transoperative period, body temperature, respiratory rate, heart rate and oxygen saturation, and noninvasive blood pressure had been monitored. They have been measured immediately prior to administration of anesthetic drugs (T0-Control) and every 4 minutes during 20 minute of transoperative period (T4, T8, T12, T16, T20); heart rate parameters; respiratory rate, body temperature, oxygen saturation level and systolic blood pressure (SBP). The Tramadol group presented lower values-of heart rate and respiratory rate when compared to those obtained in the Control group in the periods from T0 to T8. In all analyzed moments body temperature and oxygen saturation did not reveal significant difference between the two groups; with values-between 35.6° C and 37.7° C and 78.5% and 90.25%, respectively. In this study it was possible to conclude that Tramadol was efficient in analgesia after surgical sterilization of prepubertal cats, without causing significant hypotension.

A dog was consulted with functional disability of the right thoracic limb. Radiographic image showed lateral luxation of the scapulohumeral joint. The animal was submitted to surgical treatment using tension suture with screws and Nylon wire, with satisfactory result and functional use of the limb 30 days postoperatively.
