Técnicas de contenção química em cachorro-do-mato (Cerdocyon thous) Techniques of chemical restriction in crab eating fox (Cerdocyon thous)

It is highly difficult to find literature references about the effects of dissociative anesthetics drugs on wild animals. This work aims to determine the effects of various anesthetic protocols on crab eating fox. Five healthy male animals were used. After 12 hours fast each animal were treated with three dissociative anesthesia protocols (QX – ketamine and xylazine, QM – ketamine and midazolam, TZ – tiletamine and zolazepam) at 30 days interval. The variables analyzed were: latency period; able anesthesia period; induction quality, anesthesia maintenance and recover. We available cardiac frequency (CF), oxyhemoglobin saturation (SpO 2 ), cardiac rhythm, respiratory frequency (RF), body temperature (BT) and muscle relaxing five minutes after the latency period and every 10 minutes during the period of anesthesia maintenance (M10 a M40). The parametric dates was analyzed by analysis of variance and Tukey test for comparison between the medium of groups and times, with significative difference fixed in p<0.05. The group QX showed lower CF valor compared with other groups in all the times and high incidence of sinus arrhythmia was observed. The RF showed lower valor in QX group compared with a TZ group. The SpO 2 showed difference between QX group and QM group only in the time M10. No significative difference was observed in the latency time between all groups. The animals showed good quality of induction and recovered, without adverse effects. In conclusion the ketamine and xylazine association could be used with restrictions, because showed cardiac.
