RESUMO

Descorna cirúrgica em bovinos é uma prática bastante realizada na medicina veterinária, com indicação principalmente para evitar acidentes com fraturas, trabalhadores e outros animais. O objetivo do presente relato seria ressaltar o uso de analgésicos e sedativos em bovinos submetidos a este procedimento cirúrgico, compartilhar técnica cirúrgica utilizada, informações de monitoramento de sinais vitais no trans cirúrgico e recomendações pré, trans e pós-cirúrgicas, assim como possíveis complicações. Foi atendido um bovino da raça Jersey, fêmea, 1 ano de idade, pesando cerca de 222kg, submetido a descorna bilateral devido ao comportamento agressivo. Contido em tronco de contenção e tranquilizado com acepromazina, recebeu meloxicam e associação de sulfa com trimetropim. Após tricotomia e antissepsia foi realizado bloqueio perineural do ramo cornual do nervo zigomático temporal e bloqueio infiltrativo ao contorno de cada corno com lidocaína sem vasoconstritor. Com os cornos insensíveis, se deu início ao procedimento de descorna cirúrgica pela associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber. Concluímos ser de extrema importância a execução da técnica cirúrgica por médico veterinário apto, realizando o procedimento de forma asséptica e com analgesia visando o bem estar do animal. No caso em questão, a associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber foi parcialmente satisfatória, o animal apresentou boa margem de fechamento da sutura e sem deiscência dos pontos, porém houve dificuldades de retirada de margens ósseas pontiagudas após uso do alicate. A tranquilização associada ao bloqueio local foi efetiva para tal procedimento.(AU)

Surgical dehorning in cattle is widely performed practice in veterinary medicine, primarily indicated to prevent accidents involving workers, fights between animals, and skull fractures. This procedure involves the removal of the horns of the horns of cattle and should be performed using ethical methods by a qualified veterinarian. The objective of this case report is to highlight the use of analgesics and sedatives in cattle undergoing this surgical procedure, share the surgical technique employed, information on vital sign monitoring during the procedure, and pre-, intra-, and post-surgical recommendations, as well as potential complications. A Jersey cattle, female, 1 year old, weighing approximately 222kg, underwent bilateral dehorning due to aggressive behavior. Restrained in a cattle chute and tranquilized with acepromazine, she received meloxicam and a combination of sulfadiazine with trimethoprim. After trichotomy and antiseptic preparation, perineural blockade of cornual branch of the zygomatic temporal nerve was performed, follows by infiltrative blockade around each horn with lidocaine without vasoconstrictor. With the horns desensitized, the surgical dehorning procedure began using a combination of Gigli saw and Dick Kaber-type wire snare. In conclusion, it is of utmost importance for the surgical technique to be performed by a qualified veterinarian, ensuring aseptic procedure and correct analgesia for the well-being of the cattle. In this case, the combination of Gigli saw and Dick Kaber-type wire snare was partially satisfactory; the animal had a good suture closure margin and did not present suture dehiscence, but there were difficulties in we moving pointed bony margins after using the wire snare. Tranquilization combined with local blockade was effective for this procedure.(AU)

El objetivo de este informe sería resaltar el uso de analgésicos y sedantes en bovinos sometidos a este procedimiento quirúrgico, compartir la técnica quirúrgica utilizada, información sobre el monitoreo de signos vitales durante la cirugía y recomendaciones pre, trans y posquirúrgicas, así como posibles complicaciones. Se trata de una hembra bovina Jersey, de 1 año de edad, con un peso aproximado de 222 kg, siendo sometida a descornado bilateral por comportamiento agresivo. Se recibieron contenidos en un baúl de contención y tranquilizados con acepromacina, meloxicam y una combinación de sulfas y trimetopim. Mediante tricotomía y antisepsia se realizó bloqueo perineural de la rama cornual del nervio temporal cigomático y bloqueo infiltrativo en todo el contorno de cada miembro con lidocaína sin vasoconstrictor. Con cuerpos insensibles se inició el procedimiento de descornado quirúrgico, combinando técnicas de aserrado con alicates Dick Kaber. Concluimos que es de suma importancia realizar la técnica quirúrgica por un veterinario calificado, realizando el procedimiento de manera aséptica y con analgesia administrada para el bienestar del animal. En el caso que nos ocupa, la asociación de técnicas de la sierra con la pinza tipo Dick Kaber fue parcialmente satisfactoria, el animal presentó un buen margen de cierre de sutura y ninguna dehiscencia de los puntos, sin embargo, hubo dificultades para eliminar los márgenes óseos afilados después de usar alicates La tranquilidad asociada al bloqueo local fue eficaz para este procedimiento.(AU)

RESUMO

Background: Cystic endometrial hyperplasia is a hormone-dependent disease induced by systemic increase in progesteronethat can occur in several domestic species, such as the rabbit. This disease may be associated with sex steroid hormones,especially progesterone, and may be asymptomatic, and it is diagnosed using complementary imaging tests such as totalabdominal ultrasound. However, surgical excisional biopsy with histopathological tissue analysis is the gold standard. Thisstudy reports a case of asymptomatic cystic endometrial hyperplasia in a female Miniature Lion Lop rabbit (Oryctolaguscuniculus domesticus) treated with therapeutic ovariohysterectomy.Case: A domestic, adult, female Miniature Lion Lop rabbit (Oryctolagus cuniculus domesticus), aged approximately 5 yearsand weighing 3.2 kg, was referred to specialized care to undergo ovariohysterectomy, an elective procedure. The tutor onlyreported the occurrence of a single episode of vulvar secretion more than 2 years ago, treated with antibiotics, with remissionof clinical signs. In the intraoperative period after celiotomy, the uterine horn and uterine body showed a significant increasein volume, with abnormal color changes and tissue consistency; however, both changes were clinically asymptomatic. Subsequently, biopsy was performed during the ovariohysterectomy procedure. The excised uterus and ovaries were placed in 10%formalin and histopathologically analyzed. The macroscopic histopathological examination of the sectioned tissue revealed aslight amount of brownish fluid inside the uterine horns, in addition to multiple cystic areas in the uterine mucosa. Microscopicexamination revealed marked hyperplasia of well-differentiated endometrial epithelial cells, occasionally forming cystic structuresof different sizes. Moderate congestion, mild multifocal hemorrhage, and mild multifocal inflammatory infiltrate in the lamina...

RESUMO

Dipyrone is an effective analgesic for managing moderate or severe postoperative pain and can be used alone for mild pain or in combination with other analgesics for any type of pain. This study aimed to examine the administration of dipyrone by continuous infusion (CI) as an adjuvant analgesic in the intraoperative period for bitches undergoing elective ovariohysterectomy (OH) and its effect on these patients' cardiorespiratory parameters. Twenty bitches underwent an elective OH procedure. The pre-anesthetic agent was a combination of acepromazine and morphine. Propofol was used to induce anesthesia, and isoflurane was used for maintenance. Subsequently, the animals were randomly allocated into two groups: the dipyrone group (DG) received a bolus dose of dipyrone (25 mg kg-1) by CI at a rate of 10 mg kg-1 h, and the control group (CG) received a bolus dose and a CI of 0.9% NaCl solution, both groups at a rate of 5 mL kg-1 h. The parametric variables were analyzed by ANOVA, followed by Tukey's test (p <0.05). The paired t-test (p <0.05) was used for comparison between the groups. Statistical differences were observed for heart rate, systolic, diastolic, and mean arterial pressure, respiratory rate, and blood glucose between the periods in both groups. There were differences only in the basal values of MAP between the groups; however, most values remained within the physiological range for the species. Using the drug as an adjuvant to anesthesia did not alter cardiorespiratory parameters, and it can be used as an adjuvant in analgesia during the intraoperative period of OH.(AU)

A dipirona é um analgésico eficaz para o manejo da dor pós-operatória moderada ou grave, podendo ser utilizada isoladamente em dores leves ou associada a outros analgésicos em qualquer tipo de dor. O presente estudo teve como objetivo avaliar a utilização de infusão contínua (IC) de dipirona no período transoperatório de cadelas submetidas à Ovariohisterectomia (OH) eletiva como adjuvante analgésico, avaliando seu efeito sobre parâmetros cardiorrespiratórios desses pacientes. Para o estudo, 20 cadelas foram submetidas ao procedimento de OH eletiva. A medicação pré-anestésica foi composta pela associação de acepromazina e morfina, seguida da indução com propofol e manutenção com isofluorano. Posteriormente, os animais foram alocados, aleatoriamente, em dois grupos: dipirona (GD), que receberam bolus de dipirona (25 mg kg-1) seguido da IC do fármaco na taxa de 10 mg kg-1 h, e grupo controle (GC), cujos animais receberam o bolus e IC de solução de NaCl 0,9%, ambos os grupos na velocidade de 5 mL kg-1 h. Variáveis paramétricas foram analisadas pela ANOVA seguida pelo teste de Tukey (p <0,05) e comparadas entre os grupos pelo teste t pareado (p <0,05). Foram observadas diferenças estatísticas entre os momentos em ambos os grupos em relação à FC, FR, PAS, PAM, PAD e glicemia. Entre os grupos, houve apenas diferenças nos valores basais de PAM, no entanto, a maioria dos valores manteve-se dentro da faixa considerada fisiológica para a espécie. A utilização do fármaco como adjuvante a anestesia não alterou os parâmetros cardiorrespiratórios, podendo ser utilizado como adjuvante na analgesia durante o transoperatório de OH.(AU)

RESUMO

Background: Burns are caused by a direct or indirect action of heat on an organism, compromising the functional integrityof the skin. Hypothermia is a common intercurrence in animals during the transoperative period; thermal mattresses areused to maintain the animals body temperature, but inappropriate use can cause the patients skin to burn. In humans, burnsare quite common; however, in veterinary medicine, they are infrequent. The aim of this study was to describe a case ofaccidental burn in a canine caused by a thermal mattress, emphasizing wound treatment and analgesia used.Case: A 12-year-old male canine without defined breed weighing 15 kg underwent an emergency exploratory laparotomydue to rupture of a spleen mass and presented with intercurrence hypothermia during the anesthesia procedure, which wascontrolled using a thermal mattress. Ten days after the surgical procedure, he developed a skin lesion with erythema, suffusion, and necrosis, evolving skin displacement along the entire back with a lot of pain which was possibly caused by theuse of a thermal mattress in the transoperative procedure. The intuited analgesic treatment involved the use of numerousand different drugs, including Methadone (0.3 mg/kg, QID, SC), Dipyrone (25 mg/kg, TID, IV), and Ketamine (0.5 mg/kg,TID, SC) (during hospitalization), as well as Tramadol (4 mg/kg, TID, PO) and Dipyrone (25 mg/kg, TID, PO) after medicalrelease as support therapy. For the wound treatment, calcium alginate was initially used daily and subsequently changedfor daily application of dermisana oil. The patient followed up weekly for approximately two months for wound monitoring as well as adjustments to the drug therapy. The would almost completely healed, but the patient showed a significantworsening in the general clinical condition correlated with the neoplasm that he had, and the owner and clinical staff ofthe veterinary hospital opted for euthanasia...(AU)

RESUMO

Background: The taxonomic order Anura is composed of frogs and toads, with approximately 6,000 species worldwide, of which 900 species are found in Brazil. Rhinella marina, popularly known as "sapo-cururu," is the most commonly found frog in Brazil. Although most of these animals are found in research laboratories and zoos, they are increasingly being reared as pets. Therefore, sedation or anesthesia is often necessary for these animals to facilitate medical care, complementary examinations, or surgical procedures. However, there are only a few reports of anesthesia in frogs. Therefore, the present report aimed to describe the anesthetic protocol for femoral osteosynthetic surgery in an adult cane toad. Case: An adult cane toad presented with a history of difficulty in moving the left hindlimb and loss of limb movements. Radiography showed a simple, complete, transverse, and closed average shaft of the left femur and bone shaft fracture deviation. The animal was referred for an osteosynthetic surgery to stabilize the fracture. Animal restraint was performed using humidified gloves on the operating table. As premedication, ketamine, meloxicam, and morphine were administered, and general anesthesia was induced with isoflurane through a face mask. The anesthesia was maintained with isoflurane through a drip on the animal's back for cutaneous absorption. Lidocaine (2%) anesthetic gel was applied on the incision line to complement the somatic analgesia. The fracture was fixed using an intramedullary Kirschner pin. The heart rate was measured based on the beep of the arterial pulse using a Doppler ultrasonic device, respiratory rate was recorded by visual observation of the animal's respiratory motion, and body temperature was assessed using an esophageal digital thermometer - all of these remained stable during the procedure. Morphine, enrofloxacin, and meloxicam were administered postoperatively. The animal was discharged from the hospital seven days after the surgery, and 14 days later, the animal was deemed clinically stable with favorable wound healing. Discussion: Toads use their skin to breathe and maintain osmotic balance. Therefore, their skin is extremely sensitive to dehydration, requiring constant wetting. General anesthesia in amphibians is recommended for prolonged and painful procedures, as in the present case. Different anesthetics, analgesics, and associated drugs may be used. Ketamine is often used for chemical restraint in amphibians, and the induction and recovery times may vary due to sensitivity and drug resistance. Inhalational anesthesia with isoflurane may also be effective; in the present case, the anesthetic was administered using a mask placed on the frog's skin, without any irritation. Analgesia is essential for any animal, and amphibians have opioid receptors that may be used as targets of non-steroidal anti-inflammatory agents. As indicated for all species, the animal was monitored throughout the procedure. Assessment of heartbeat is the simplest way to monitor anesthesia using Doppler (on the heart or throat); in the present case, was placed on the axillary artery for clear auscultation. In addition, other parameters, such as temperature and primary respiratory movements, were monitored. Anesthetic recovery can take hours or even days, whereas excretion depends on the metabolic rate of each animal. In the present case, recovery was observed 4 h after completion of the procedure, using fresh water on the animal's body to accelerate recovery, as indicated in the literature. This case demonstrated that anesthesia and medications used for anesthesia induction, maintenance, and recovery are safe in toads. For cane toads, during femoral osteosynthesis, this anesthetic procedure has never been described previously in the literature. Finally, such information can aid veterinarians in performing safe and adequate analgesic and anesthetic procedures for the wellbeing of animals.

RESUMO

Este trabalho visa, por meio de levantamento de dados científicos, analisar a melhor abordagem anestésica para cada tipo de paciente de risco, mostrando um panorama geral e indicativo sobre os fármacos e sua funcionalidade para cada sistema. A revisão bibliográfica foi baseada na literatura encontrada em meios eletrônicos (plataformas PubMed, Scielo e Google Scholar) e físicos (livros de referência) nos últimos dez anos, dentro de artigos com relatos de caso, revisões de literatura e pesquisas inéditas. Dessa forma, obteve-se um levantamento amplo, abrangendo as principais classes farmacológicas utilizadas em procedimentos anestésicos em pacientes classificados como de risco, ou seja, cardiopatas, nefropatas, hepatopatas, pediátricos e senis, procurando determinar os que causam menor depressão cardiovascular e respiratória respeitando suas limitações. Sendo assim, para uma anestesia mais segura deve-se focar na prevenção de intercorrências anestésicas no transoperatório e pós-operatório. Observar, estudar, analisar o paciente e o protocolo a ser utilizado como um todo é necessário e indispensável na anestesiologia veterinária, associando a teoria com a prática.(AU)

This work aims, through research, with scientific data, to analyze the best anesthetic approach for each type of patient, showing a general and indicative overview about the drugs and their functionality for each system. The bibliographic review was based on the literature found in electronic media (PubMed, Scielo and Google Scholar platforms) and physical (reference books) in the last ten years, within articles with case reports, literature reviews and unpublished research. Thus, a broad survey was obtained, covering the main pharmacological classes used in anesthetic procedures in patients classified as at risk, that is, cardiopath, nephropath, liver disease, pediatric and senile patients, trying to determine those that cause less cardiovascular and respiratory depression respecting their limitations. Therefore, for safer anesthesia, focus must placed on preventing anesthetic complications in the intraoperative and postoperative periods. Observing, studying, analyzing the patient and the protocol to be used as a whole is necessary and indispensable in veterinary anesthesia, associating theory with practice.(AU)

RESUMO

Background: The knowledge of secure anesthetic protocols for reptiles is very important, especially because they are aggressive species and they have peculiar physiology, unpredictable reactions to the same drug in different environmental conditions and different physiological responses can be observed. The anesthetic protocol aims immobilization, analgesia and muscle relaxation for adequate, safe and easily reversible anesthesia. Few reports have been described on anesthesia in animals and, before that, the objective of this study is to report the anesthetic protocol that was used and vital parameters monitoring in an Alligator mississipiensis that was submitted to surgery for limb amputation. Case: A female American alligator was attended, with about 8-year-old, 2 m long and 268,964 pounds, with fight history with other animal six months ago, resulting in a wound in the right toracic limb. When the lesion occurred, it was the breeding season of the species, so we chose not to perform the treatment at that time. An X-ray of the member was performed, which showed, among other changes, osteomyelitis and septic arthritis. Thus, the limb amputation was indicated. Ketamine association (10 mg/kg) and medetomidine (0.1 mg/kg) were used as anestesic premedication, both administered intramuscularly. For anesthetic induction, propofol (4 mg/kg) intravenously was used. The animal was [...](AU)

A doença do disco intervertebral (DDIV) é uma das causas mais comuns de alterações neurológicas em cães [2], sendo provocada pela degeneração do disco intervertebral. Pode ocorrer extrusão (Hansen tipo I) ou protrusão (Hansen tipo II) do disco, as quais podem causar compressão da medula ou das raízes nervosas, e até concussão medular [7]. É observada com frequência em raças condrodistróficas, com idade entre três e sete anos [1,6].Os sinais clínicos são variáveis e dependem da localização da lesão, do volume de material no interior do canal vertebral e da velocidade com que esse material é ejetado, variando desde hiperestesia espinhal até paraplegia com perda da percepção à dor profunda. O tratamento de cães com DDIV toracolombar pode ser clínico ou cirúrgico, dependendo do grau de disfunção neurológica [2].As indicações para o tratamento cirúrgico da DDIV são a falta de resposta ao tratamento clínico, os sinais clínicos recidivantes ou progressivos, a paraparesia não-ambulatória, paraplegia com preservação da nocicepção (dor profunda) e paraplegia e ausência da nocicepção (grau V) com duração inferior a 48 horas [2,7]. Os objetivos do tratamento cirúrgico na DDIV são: a descompressão da medula espinhal, a remoção do material do interior do canal vertebral, a redução do edema, o alívio da dor e a prevenção de futuras extrusões [7].
