The mortality rate of cats undergoing sedation is significantly higher than dogs, so it is fundamental that the sedatives provide good cardiovascular stability. Dexmedetomidine (DEX) is an α2-adrenergic receptor agonist utilized in cats to provide sedation and analgesia, although studies have been utilized high doses, and markedly hemodynamic impairments were reported. The aim of this study was to prospectively investigate how the sedative and electrocardiographic effects of a low dose of DEX performing in cats. Eleven healthy cats were recruited; baseline sedative score, systolic arterial pressure, electrocardiography, and vasovagal tonus index (VVTI) were assessed, and repeated after ten minutes of DEX 5μg/kg intramuscularly (IM). A smooth sedation was noticed, and emesis and sialorrhea were common adverse effects, obser...

Com isso, surge a necessidade da expansao dos conhecimentos sobre cada especie, pois, assim, sera possivel oferecer um manejo terapeutico mais adequado a cada individuo respeitando suas peculiaridades. Dentro das diversas areas da Clinica Medica de Animais Silvestres, pode-se destacar a Oftalmologia, a qual apresenta significativa expansao, seja pela necessidade eminente de conhecimento na area de anatomia de animais silvestres para posterior uso na clinica medica e cirurgica, seja pela necessidade advinda do manejo de preservacao e/ou ainda a clinica particular, pois torna-se irrefutavel que, a cada dia, ha a introducao de diversos animais selvagens como de companhia. O presente estudo teve como principal objetivo descrever os parâmetros oftalmicos e biometricos do bulbo ocular do gato-do-mato, Leopardus tigrinus, com auxilio da ultrossonografia, ale...

However, it has a low sensitivity and specificity for diagnosis of cardiac chamber overload. The accuracy of electrocardiographic interpretation can be improve using new cut-offs for the duration and amplitude of the electrocardiographic waves. Our objective was to evaluate the use of the electrocardiogram in the diagnosis of atrial and ventricular overload, using echocardiography as the gold standard test for the diagnosis of atrioventricular overload. We aimed to define new cut-off values that would increase the sensitivity and specificity of the electrocardiogram for diagnosis of chamber overload in dogs.Materials, Methods & Results: Eletrocardiogram records were obtained in 81 dogs divided into 3 groups: Group 1A (healthy dogs 10 kg); Group 1B (dogs 10 kg with mitral or tricuspid valve disease); Group 2 (dogs weighing between 10.1 and 20 kg) and Group 3 (dogs > 20.1 kg). Duration in mi...
