Background: The Coragyps atratus flies long distances in search of food and has a marked behaviour of food competition. Since they are frequently found in areas of recent human occupation, they are subject to trauma, which may require surgical interventions. Locoregional blocks are used as part of a balanced-anaesthesia protocol and are currently being evaluated in birds, with brachial plexus block being the main technique described in the literature. However, to our knowledge, this is the first description of intravenous regional anaesthesia (Bier's block) in a vulture. Thus, we aim to report the use of Bier's block with 1% lidocaine, in a black-headed vulture submitted to digit amputation. Case: A black-headed vulture (Coragyps atratus), weighing 2 kg, was rescued and referred to the Veterinary Hospital due to its inability to fly. Physical examination revealed a swollen digit in the right pelvic limb. Radiographic examination confirmed the intermediate phalanx fracture of the 4th digit of the right pelvic limb with signs suggestive of advanced osteomyelitis. The animal was referred to surgery for amputation of the affected digit. Before surgery, water and food were withdrawn for 12 h. Pre-anaesthetic medication consisted of 1 mg/kg midazolam and 0.5 mg/kg morphine intramuscularly (IM). Anaesthetic induction was performed through face mask with isoflurane, followed by orotracheal intubation with a 3 mm-endotracheal tube. Anaesthesia was maintained with isoflurane through a non-rebreathing circuit in 100% oxygen. Using a multiparametric monitor, heart rate (HR), respiratory rate (RR), end-tidal CO2 (EtCO2 ), oxyhemoglobin saturation (SpO2 ), electrocardiography (ECG), systolic blood pressure (SBP) and core temperature (CT) were evaluated. Antisepsis of the right pelvic limb was performed and an elastic band was applied around the distal region of the affected tibia to serve as a tourniquet. A scalp vein set was used to access the lateral saphenous vein in the region distal to the tourniquet, and 5 mg/ kg lidocaine 1% was injected intravenously. The patient remained stable during the procedure, with no need for analgesic rescue. The tourniquet was gradually released 40 min past its application, being completely removed after 45 min of surgery. The anaesthetic supply was interrupted, with extubation after 4 min; the patient had satisfactory anaesthetic recovery. Discussion: The present report describes the success in using the technique of intravenous regional anaesthesia with 1% lidocaine for digit amputation performed on a specimen of black-headed vulture. The pre-anaesthetic medication provided analgesia, satisfactory sedation for venoclysis, and anaesthetic induction without complications. Anaesthetic induction and maintenance in birds are preferably performed with inhaled anaesthetics, thus the choice of mask induction. Despite the reduction in RR soon after induction, the patient remained on spontaneous ventilation. Bier's block using 5 mg/kg lidocaine showed to be an easy and safe technique in vultures, but doses up to 6 mg/kg lidocaine are not associated with adverse effects in birds. The intravenous regional anaesthesia technique described in this manuscript promoted adequate analgesia for the digit amputation procedure in black-headed vultures and allowed hemodynamic stability without significant anaesthetic complications. Thus, the present report points to the potential use of this locoregional block in other birds.

Behavioral disorders, including noise phobia, have a great impact on small animals internal medicine, impairing their quality of life as well as their life expectancy. The objective of this work is to report the case of a male dog who suffered from noise phobia and panic attacks triggered by thunderstorms and fireworks, and did not respond to previous training and treatment. After clinical and laboratory evaluations, he was treated with 2mg/kg clomipramine twice daily for 90 days associated with 0.06mg/kg alprazolam as needed on those days of intense fear. During the first week of treatment, a significant improvement could already be observed, with reduction in destructive behaviors, which lingered on for up to eight months of follow-up. The treatment stabilized the clinical condition and improved the patient’s quality of life.


Os distúrbios de comportamento, entre eles o medo de ruídos, apresentam um grande impacto na clínica de peque-nos animais, acarretando em decréscimo na qualidade e expectativa de vida. O objetivo deste trabalho é relatar o caso de um cão, macho, com histórico de medo de ruídos, que apresentava quadros de pânico desencadeados por trovões e fogos de arti-fício, sendo refratário a tentativas prévias de adestramento e tratamento medicamentoso. Após avaliação clínica e laboratorial, instituiu-se tratamento com clomipramina 2mg/kg BID durante 90 dias associada à administração de alprazolam 0,06mg/kg conforme necessário nos dias de medo intensificado. Na primeira semana de tratamento observou-se melhora significativa, com redução dos comportamentos destrutivos, se estendendo até 8 meses de acompanhamento. O tratamento realizado proporcio-nou estabilização do quadro clínico e incremento na qualidade de vida do paciente. informação a ser inserida pelos autores.

This is the case of a specimen of Didelphis albiventris with signs of respiratory difficulty after a dog attack. Thoracic radiographic examination revealed pneumothorax, pulmonary contusion, and rib fracture, but no alteration compatible with diaphragmatic hernia was observed. Pneumothorax was reduced and the other alterations were treated. However, clinical manifestations persisted, and thus a contrast-gastrointestinal radiographic study was performed, showing abdominal organs in the thoracic cavity and loss of diaphragmatic line. The surgical approach was instituted, with access to the diaphragm through median laparotomy. Through the diaphragmatic rupture, present in the left antimere, there were herniated liver and gastric portions, intestinal segments, and omentum. After inspection and repositioning of the abdominal organs, the diaphragm raffia was performed with single sutures interrupted with 3-0 Nylon thread. The patient’s complete recovery occurred 14 days after the surgical procedure, with remission of clinical manifestations and normality of thoracic images in radiographic studies.


Esse é o caso de um espécime de Didelphis albiventris com sinais de dificuldade respiratória após ataque por cão. O exame radiográfico torácico revelou pneumotórax, contusão pulmonar e fratura de costelas, porém nenhuma alteração com-patível com hérnia diafragmática foi observada. O pneumotórax foi reduzido e as demais alterações tratadas. Contudo; houve a persistência das manifestações clínicas, e dessa forma um estudo radiográfico gastrointestinal contrastado foi realizado, sendo evidenciados órgãos abdominais na cavidade torácica e perda da linha diafragmática. A abordagem cirúrgica foi instituída, com acesso ao diafragma por meio de laparotomia mediana. Através da ruptura diafragmática, presente no antímero esquerdo, estavam herniadas porções hepáticas e gástricas, segmentos intestinais e omento. Após inspeção e reposicionamento dos órgãos abdominais, a rafia do diafragma foi realizada com suturas simples interrompidas com fio Nylon 3-0. A recuperação completa do paciente ocorreu 14 dias após o procedimento cirúrgico, com remissão das manifestações clínicas e normalidade das ima-gens torácicas nos estudos radiográficos.

Background: The term “rabbit gastrointestinal syndrome” (RGIS) refers to a decrease in peristaltic movements, which insome cases can progress to absolute inactivity of the digestive apparatus. This condition is mostly secondary to others thatpromote changes in gastrointestinal motility, such as dehydration, fiber deficiency, excess carbohydrates in diets, stress,and acute or chronic painful processes. Clinical manifestations are mostly nonspecific. Thus, a case of RGIS resultingfrom environmental change in a domestic rabbit (Oryctolagus cuniculus) is reported.Case: A 4-month-old male domestic rabbit weighing 0.962 kg was referred to a university veterinary hospital. The patient had a history of absence of defecation and anorexia for the past two days. The owner reported that the patient wasapathetic but became aggressive when manipulated. The changes started after a move of residence. On physical evaluation, an increase in abdominal volume and a painful response to touch on the abdomen were observed. Complementaryexaminations were performed, such as a blood count and an ultrasound study. The blood tests showed no alterations,but the ultrasound evaluation showed the presence of free abdominal fluid, dilated intestinal loops due to fluid content,reduced gastrointestinal motility, and a hyperechoic structure associated with acoustic shading in the small intestine, allfindings suggestive of obstruction. Given the failure of clinical management, the patient was referred for an exploratorylaparotomy procedure followed by enterotomy. The obstruction point was located near the ileocecal junction. After surgery,analgesics, antibiotics, fluid therapy, anti-inflammatory drugs, intestinal motility inducers, and probiotics were prescribed.One week after the surgical procedure, the patient showed improvement in the clinical condition, with normal appetite,defecation, and docility...

Background: The South American coatis (Nasua nasua) are capable of adapting to different habitats, which allowed themto exchange between domestic and wild areas, increasing the occurrence of traumas. Procedures performed in this speciesdemand anesthetic protocols that take comorbidities into account and cause minimal cardiorespiratory depression as wellas rapid recovery. It is in such context that locoregional anesthesia has become an essential tool. Thus, we aim to reportthe use of two techniques of locoreginal block: brachial plexus block and lumbosacral epidural block, in a Nasua nasuasubmitted to osteosynthesis of the radius and caudectomy due to trauma.Case: A adult male coati weighing 2.3 kg was referred to the Veterinary Medical Teaching Hospital of the UniversidadeFederal do Paraná (UFPR) - Setor Palotina with a history of trauma. Physical examination showed crackling in the radius and ulnar region, and also abnormal angulation in the distal portion of the tail. After taking x-rays, fractures wereconfirmed in the distal radius and in the distal portion of the tail. The patient was referred for surgery. After 8 h of waterand food withdrawal, the animal was premedicated with a combination of ketamine (10 mg/kg), midazolam (0.3 mg/kg)and methadone (0.2 mg/kg), intramuscularly (IM). Induction of anesthesia was performed with propofol titrated to effect(total dose 4 mg/kg) and anesthesia was maintained with isoflurane in spontaneous ventilation using a non-rebreathingcircuit (Baraka). It was evaluated heart rate (HR), respiratory rate (RF), end-tidal CO2 (EtCO2), expired isoflurane fraction (FE´Iso), oxyhemoglobin saturation (SpO2), electrocardiography (ECG), systolic blood pressure (SBP) and coretemperature (CT) using a multiparametric monitor. After the stabilization period, the animal was positioned in lateral...

Sugar has healing action, but not always the grain form is ideal. This study evaluated the effi ciency of sugar in different formulations in healing by second intention in rats. Held a surgical wound was treated with 0.9% NaCl (G1); crystal sugar (G2); carboxymethylcellulose gel (G3); carboxymethylcellulose gel plus sugar (G4); chlorhexidine (G5); chlorhexidine associated with sugar (G6); healing and antibacterial commercial ointment (G7). In D2 (second day after surgery), D4, D7, D10, D14, D21 and D30, one animal of each group was euthanized. Macroscopically, there was no edema and no infection, but it was found crust evident in G2, G4 and less intense absent in G6 and G7. Microscopically, in G5, G6 and G7 there was necrosis and infl ammation for less time, early granulation and epithelialization fi broplasia and more intense, leading to tissue repair in the G7 D10 and D14 in the other groups. Concluding, the combination of chlorhexidine with sugar (2:1) is effective for wound healing by second intention in rats because it reduces the necrosis and infl ammation, increases fi broplasia and promotes the formation of granulation tissue, resulting in early tissue repair.(AU)


O açúcar tem ação cicatrizante, mas nem sempre a forma granulada é ideal. Este estudo avaliou a eficiência do açúcar em diferentes formulações na cicatrização por segunda intenção em ratos Wistar. Realizada uma ferida cirúrgica, houve tratamento com NaCl 0,9% (G1); açúcar cristal (G2); gel de carboximetilcelulose (G3); gel de carboximetilcelulose acrescido de açúcar (G4); clorexidina (G5); clorexidina associada ao açúcar (G6); pomada comercial cicatrizante e antibacteriana (G7). Em D2 (segundo dia de pós-operatório), D4, D7, D10, D14, D21 e D30, um animal de cada grupo foi submetido à eutanásia. Macroscopicamente, não houve edema e nem infecção, mas verificou-se crosta, evidente em G2, menos intensa em G4 e G6 e ausente em G7. Microscopicamente, em G5, G6 e G7 houve necrose e inflamação por menos tempo, granulação mais precoce e fibroplasia e reepitelização mais intensas, levando à reparação tecidual em D10 no G7 e em D14 nos demais grupos. Conclui-se que a associação de açúcar à clorexidina (2:1) é eficiente na cicatrização de feridas por segunda intenção em ratos Wistar, pois reduz a necrose e a inflamação, favorece a fibroplasia e a formação do tecido de granulação, tornando a cicatrização mais precoce.(AU)
