| ABSTRACT Eyes from brachycephalic dogs were studied by acoustic radiation force impulse (ARFI) elastography to establish quantitative and qualitative reference values related to the shape and rigidity of some ocular structures. Eighty-four eyes from 42 adult brachycephalic dogs were included in this study. Animals were subjected to physical, laboratory, and ophthalmic examinations. Following confirmation of good health, the dogs were subjected to ultrasonography and ARFI elastography, emphasizing the optic nerve, ciliary body, and lens. On qualitative elastography, homogeneous characteristics were observed on the ciliary body and optic nerve. Aqueous and vitreous humors were visualized as mosaic-like images. Quantitative elastography showed the mean optic... |

| It was studied fortuitous cardiorespiratory and bispectral index changes in dogs anesthetized with isoflurane associated or not to tramadol. Sixteen dogswere distributed in two groups named CG (control group) and TG (tramadol group). General anesthesia was induced in all animals with isoflurane via mask. After 10 minutes, the animals of CG received 0.05ml/kg of saline solution at 0.9%, and TG received 2mg/kg of tramadol, both via intramuscular. It was evaluated heart rate, systolic, diastolic and mean arterial pressures; electrocardiography; respiratory rate; oxihemoglobin saturation; end tidal carbon dioxide; bispectral index and recovery of anesthesia. The administration of tramadol in dogs anesthetized with isoflurane did not produce changes in... |

| ABSTRACT The aim of this study was to establish normal baseline ERG values of 23 anesthetized deer belonging to 8 neotropical species (Mazama americana, Mazama nemorivaga, Mazama gouazoubira, Mazama nana, Mazama bororo, Ozotocerus bezoarticus, Odocoileus virginianus and Blastocerus dichotomus). Only right eyes were studied. Chemical restraint was performed using xylazine associated with ketamine, IM, for M. americana, M. gouazoubira, M. nemorivaga, M. nana, M. bororo, O. bezoarticus and O. virginianus. A combination of tiletamine/zolazepam diluted in xylazine 2% was used for B. dichotomus individuals. After 20min of dark adaptation, electroretinograms were obtained using a handheld electroretinography (ERG) machine using the QuickRetCheck Protocol at three... |

| The effects of continuous rate infusion of lidocaine or amiodarone on hemodynamic and arrhythmias induced by epinephrine in dogs anesthetized with halothane were evaluated. Thirty dogs were distributed into three groups: amiodarone group (AG), lidocaine group (LG), or control group (CG). Anesthesia was induced with etomidate and maintained with halothane. Thirty minutes later a bolus and continuous rate infusion (CRI) of amiodarone in AG, lidocaine in LG and NaCl at 0.9% in CG was administered. After 10 minutes, arrhythmias were induced by epinephrine CRI at 0.0001mg/kg/minute, which was increased in 0.0001mg/kg/minute every ten minutes, until 0.0003mg/kg/minute. The measurements were performed 30 minutes after the induction of anesthesia (T0), 10 minutes... |

| Avaliaram-se os efeitos da infusão de diferentes doses de lidocaína sobre o ritmo cardíaco, em cães anestesiados com isofluorano que receberam doses crescentes de adrenalina. Foram utilizados 10 cães, cada qual anestesiado quatro vezes, respeitando-se um intervalo de duas semanas. A indução anestésica foi realizada com propofol, 8mg/kg, e a manutenção com isofluorano a 1,5 CAM. Os animais foram distribuídos em quatro grupos, que receberam bolus de lidocaína, 1mg/kg, seguido pela infusão de lidocaína nas taxas de 50μg/kg/h (G50), 100μg/kg/h (G100) e 200μg/kg/h (G200). O grupo-controle (GC) recebeu bolus e infusão de NaCl a 0,9%. As variáveis foram mensuradas 30 minutos após a indução, e em seguida, iniciadas as infusões. Após 10 minutos do princípio dos... |

| A técnica de analgesia multimodal, por meio da infusão contínua de fármacos, pode ser empregada para diminuir a incidência de sensibilização central durante a anestesia. Avaliaram-se as características cardiorrespiratórias, durante o procedimento de artroscopia de joelho, em cães anestesiados com isofluorano e monitorados por meio do índice biespectral, submetidos à infusão contínua de morfina ou fentanil, associada à lidocaína e cetamina. Utilizaram-se 16 cães adultos, machos ou fêmeas, os quais foram distribuídos aleatoriamente em dois grupos, denominados MLK - que recebeu morfina (3,3μg/kg/min), lidocaína (50μg/kg/min) e cetamina (10μg/kg/min) ou FLK - em que foi substituída a morfina pelo fentanil (0,03μg/kg/min). Os cães foram pré-tratados com... |
