The technique proved easy to perform, safe, and effective.

RESUMO.-Com este estudo objetivou-se descrever a topografia do cone medular do macaco-prego (Sapajus libidinosus) a fim de fornecer suporte para que a realização de procedimentos anestésicos, bem como exames de mielografia e coleta de líquor, dentre outros procedimentos que utilizam a via epidural. Para tanto foram dissecados oito animais, sendo seis machos e duas fêmeas, de diferentes faixas etárias. Rebateu-se a pele para retirada da musculatura da região dorsal, exposição de toda a coluna vertebral e identificação das vértebras lombares e sacrais. Para estabelecer o final da medula espinhal e medir o comprimento This study aimed to describe the topography of the conus of capuchin monkey (Sapajus libidinosus) to provide support for anesthetic procedures, as well as examinations of myelography and CSF collection, among other procedures using the epidural route. Eight animals were dissected, six males and two females, of different ages. The skin was countered for removal of the dorsal musculature for exposure of the entire spine and identification of the lumbar and sacral vertebrae. To establish the end of the spinal cord and to measure the length of the conus medullaris, we opened the lumbosacral spinal canal through side section of the vertebral arches. The dura mater was sectioned to visualize the conus and to observe the topographical relation with the vertebrae. All animals showed five lumbar vertebrae and three sacral vertebrae. The vertebrae were in general very closed with the spinous processes well developed and directed cranially. The conus of capuchin monkeys was located between the L2 and L5 vertebrae, with the base mostly in the L3 vertebra, and the peak in L4. The body length (interarcual space occiptoatlântico until sacrocaudal interarcual space) ranged from 22.9 to 31.8cm, with a mean of 27.44±3.1cm while the medullary cone length ranged from 1.70 to 3.51cm, with a mean of 2.47±0.57cm. There was no correlation between body size and length of the medullary cone (r=0.212). It is concluded that despite the variations in length and positioning of the medullary cone, its height does not exceed the lumbosacral joint, making safe access to the epidural space in this way.

The femoral vein was shown to be the most suitable for blood sampling and drug administration and the saphenous vein for serum therapy protocols.

Background The aim of study was to evaluate the efficacy of the supraclavicular brachial plexus block technique in Sapajus libidinosus. Methods Were used eight animals, which were sedated, anesthetized, kept under hypnosis, and submitted to plexus block using a neurolocalizer. The physiological parameters, the nociception and response threshold (mA), were evaluated before and after the block. The response to electrical stimulation and cutaneous sensitivity were evaluated. The groups were compared by the Tukey or Friedman test at 5%. Results The technique promoted blockage of the plexus, and movement of the thoracic limb in response to electrical stimulation decreased after 10 minutes. The applied milliampere increased after 5 minutes. The cutaneous sensitivity reflex decreased. The average time of return of spontaneous limb movement exceeded 50 minutes. Conclusions The use of 5mg/kg of lidocaine 2% promoted loss of cutaneous sensitivity and limb muscle relaxation during the evaluation period.

Capybara (Hydrochoerus hydrochaeris) is the main host of tick-borne pathogens causing Brazilian spotted fever; therefore, controlling its population is essential, and this may require chemical restraint. We assessed the impact of chemical restraint protocols on the partial pressure of arterial oxygen (PaO2) and other blood variables in 36 capybaras and the effect of different flows of nasal oxygen (O2) supplementation. The capybaras were hand-injected with dexmedetomidine (5 μg/kg) and midazolam (0.1 mg/kg) and butorphanol (0.2 mg/kg) (DMB, n = 18) or methadone (0.1 mg/kg) (DMM, n = 18). One-third of the animals were maintained in ambient air throughout the procedure, and one-third were administered intranasal 2 L/min O2 after 30 min whereas the other third were administered 5 L/min O2. Arterial blood gases, acid-base status, and electrolytes were assessed 30 and 60 min after drug injection. The DMB and DMM groups did not vary based on any of the evaluated variables. All animals developed hypoxaemia (PaO2 44 [30; 73] mmHg, SaO2 81 [62; 93] %) 30 min before O2 supplementation. Intranasal O2 at 2 L/min improved PaO2 (63 [49; 97] mmHg and SaO2 [92 [85; 98] %), but 9 of 12 capybaras remained hypoxaemic. A higher O2 flow of 5 L/min was efficient in treating hypoxaemia (PaO2 188 [146; 414] mmHg, SaO2 100 [99; 100] %) in all the 12 animals that received it. Both drug protocols induced hypoxaemia, which could be treated with intranasal oxygen supplementation.

RESUMO-Foram utilizadas oito raposas (Cerdocyon thous) adultas capturadas no município de Patos, Estado da Paraíba, Brasil, com o intuito de descrever a anatomia dos pulmões e a configuração da árvore bronquial. Os órgãos foram retirados e fixados em solução aquosa de formol a 10%. Após a descrição da morfologia externa do órgão, dissecou-se a árvore bronquial. Observou-se que o pulmão direito apresentou quatro lobos, o cranial, médio, caudal e acessório e o pulmão esquerdo mostrou apenas dois, o lobo cranial, dividido em duas porções (cranial e caudal) e o lobo caudal. A traquéia bifurcou-se sempre em dois brônquios principais, direito e esquerdo. O brônquio principal direito emitiu quatro brônquios lobares, um para cada lobo, e do brônquio principal esquerdo emergiram apenas dois brônquios, um comum à porção cranial e caudal do lobo cranial e outro para o lobo caudal. Em média, no pulmão direito, foram observados dez segmentos para o lobo cranial, dez para o lobo médio, onze para o lobo caudal e quatro para o acessório. No pulmão esquerdo foram observados apenas dois segmentos no lobo cranial, sendo, em média, onze brônquios intrasegmentares na parte cranial e dez na parte caudal do lobo, além de onze segmentos no lobo caudal, em média. Concluiu-se que o pulmão da raposa (Cerdocyon thous) apresentou características anatômicas semelhantes com o dos carnívoros e com segmentação broncopulmonar bastante variada, sendo necessário cuidado maior quando do diagnóstico de lesões pulmonares, bem como, em procedimentos cirúrgicos.
