Anestesia multimodal em cachorro-do-mato (Cerdocyon thous) submetido à hemilaminectomia e estabilização sacrococcígea / Multimodal anaesthesia in a crab-eating fox (Cerdocyon thous) undergoing hemilaminectomy and sacrococcygeal stabilization

Background: Several researches have shown the impacts of roads more directly to wildlife in Brazil. The crab-eating fox(Cerdocyon thous) is a frequent run over victim. Dissociative drugs are commonly used, but inhalation anesthesia is indicatedin cases of extensive and prolonged surgeries. Despite their similarity with domestic dogs, the literature is scarce regarding theassociation of new anesthetic techniques and protocols in wild canids. The aim of this paper was to report the viability of multimodal anesthesia in a crab-eating fox, victim of running over, undergoing hemilaminectomy and sacrococcygeal stabilization.Case: An adult male specimen of crab-eating fox was rescued after being run over and taken to a wild animal screening center.Physical examination showed superficial and deep pain, lack of support for the pelvic limbs and proprioception, increasedreflexes, and reduced tail mobility. Chemical restraint with intramuscular (IM) tiletamine-zolazepam (6.0 mg/kg) and morphine (0.5 mg/kg) was performed. Meloxicam (0.2 mg/kg IM) and enrofloxacin (5.0 mg/kg IM) were also administered. Theanimal was sequentially admitted to the veterinary hospital. Radiographic images showed compaction of the spinal columnof the T10 and T11 thoracic vertebrae and the sacrococcygeal region. Sixty min after chemical restraint, the anesthesia wassupplemented with IM tiletamine-zolazepam (4.5 mg/kg), and fluid therapy with 0.9% NaCl (10 mL/kg/h) was started. Ten minlater, intravenous propofol dose-effect (2.5 mg/kg) was administered and general anesthesia was maintained with isoflurane(FiO2 = 1.0). Thirty min after the induction of anesthesia, the animal was urdergoing hemilaminectomy and sacrococcygealstabilization. Constant rate infusions (CRI) of dexmedetomidine (0.5 μg/kg/h) and ketamine (0.6 mg/kg/h) were started. Lidocaine (7.0 mg/kg) and bupivacaine (2.0 mg/kg) were administered into the surgical site on the T10 and T11 vertebrae at 35...(AU)

Morfina epidural contínua no controle da dor pós-operatória em ovino / Postoperative pain management in a sheep using continuous epidural morphine

Background: Although ruminants experience pain like other species, diagnosis and treatment may be imprecise and challenging, especially because of lack of recognition and restraint of therapeutic resources. In addition to the restrictions inherent in the species, organic dysfunctions may further restrict the analgesic arsenal, making it necessary to find viable and effective alternative for pain control. The continuous administration of opioids in the epidural space has been highlighted as an analgesic resource in several species. However, until this moment, there are few information on this practice in ruminants. Therefore, the aim of this study was to describe the use of continuous epidural infusion of morphine in a sheep undergoing to urethrostomy with a history of chronic pain and urolithiasis.Case: A 3-year-old Santa Ines sheep, weighting 110 kg, was presented to the Veterinary Hospital of Federal University of Bahia with history of recurrent urolithiasis, lameness, severe pain and continuous use of nonsteroidal anti-inflammatory drug (NSAID). The findings of the physical examination, imaging and laboratory tests revealed possible abomasum inflammation, chronic laminitis, left humerus-radioulnar osteoarthritis and urethral urolithiasis with uremia. A clinical stabilization of the animal was performed, including an interruption of the use of the NSAID and the administration of fluid, urinary acidifier (ammonium chloride), histamine H2 receptor antagonist (ranitidine), cytoprotectant (sucralfate), antibiotic (norfloxacin) and dipyrone. After 3 days, urethrostomy was performed followed by the implantation of an epidural catheter (19G) in the lumbosacral space (L7 - S1) by means of a Tuohy needle (18G), after the surgical procedure. Administration of morphine (0.1 mg kg-1) through the catheter at 24-h intervals, associated with dipyrone (25 mg kg-1) intravenously (IV), every 8 h, over a 5-day period, was the postoperative analgesic protocol chosen.[...]

Rostral mandibular ameloblastoma in dog / Ameloblastoma mandibular rostral em um cão

Odontogenics tumors are uncommon in the dog. Ameloblastoma is considered a benign, aggressive and non-inductive odontogenic neoplasia commonly located in the incisor teeth. Its conclusive diagnosis is obtained by histopathological examination. Due to the expansive nature of this neoplasia, its resection needs to have an adequate surgical margin so it will have excellent prognostics. A canine, male, Pekingese, 8 years old had an increased volume in the rostral region of the mandible, adhered, consistency moderately firm. Radiography revealed extensive mandibular bone lysis caused by the neoplasia. Biopsy identified the tumor as ameloblastoma. Combining data from the clinical, radiographic and histopatological study and after explain to the owner regarding the postoperative esthetic it was held a bilateral rostral mandibulectomy. The fragment removed was assessed radiographically and histopathologically for evidence of tumor at its edges. The patient is active and healthy without evidence of metastasis or recurrence. The radiographic and histopathologic evaluation of edges of the fragment showed no tumor evidence. The patient is active and healthy without evidence of metastasis or recurrence since January 2010 when mandibulectomy was performed.

Os tumores odontogênicos são alterações incomuns no cão. O ameloblastoma é considerado uma neoplasia odontogênica benigna, agressiva e não indutiva, comumente localizada na região dos dentes incisivos. Seu diagnóstico conclusivo é obtido através do histopatológico. Devido ao caráter expansivo desta neoplasia uma ressecção com margem cirúrgica adequada é necessária para que se tenha um excelente prognóstico. Um canino, macho, Pequinês de oito anos apresentou um aumento de volume na região rostral da mandíbula, aderido e de consistência moderadamente firme. A radiografia mandibular demonstrou a extensão da lise óssea causada pela neoplasia. O estudo histopatológico identificou a alteração como ameloblastoma. Conciliando dados do exame clínico, estudo radiográfico e histopatológico e após o esclarecimento do proprietário a respeito da estética pós-operatória, foi realizada uma mandibulectomia rostral bilateral. A avaliação radiografica e histopatológica das bordas do fragmento não demonstraram indícios tumorais. O paciente se encontra ativo e saudável sem indícios de metástase ou recidiva desde janeiro de 2010, quando foi realizada a mandibulectomia.
