Infusão contínua de fentanil e cetamina para controle de dor no transcirurgico: relato de caso / Continuous infusion of fentanyl and ketamine for trans-surgical pain control: case report

O paciente da espécie canina, sem raça definida, com 5 anos, deu entrada a clínica veterinária particular apresentando quadro de dor aguda e intensa em cavidade abdominal associada a prostração. Foram realizados exames de sangue, ultrassonografia e radiografia de abdômen, cuja suspeita foi torção parcial do estômago, com esplenomegalia, além de gastrite e enterite. O paciente foi submetido imediatamente ao procedimento cirúrgico para alívio, reposicionamento do órgão e gastropexia. O animal foi medicado previamente com metadona, tramadol e dipirona duas horas antes do ato cirúrgico, portanto não foram utilizadas medicações pré-anestésicas e optou-se pelo propofol e cetamina para a indução anestésica, além da infusão contínua com cetamina e fentanil para se obter a analgesia multimodal. Os parâmetros de dor foram avaliados por meio das frequências cardíaca e respiratória, traçado eletrocardiográfico, pressão arterial sistólica e média, aferição da temperatura retal e coloração de mucosas, a cada 5 minutos. Os mesmos indicaram boa estabilidade hemodinâmica, segurança e analgesia, sem necessidade de alterar as doses estabelecidas durante o procedimento. Pode ser observada também redução do requerimento de isoflurano para manutenção do plano cirúrgico. O paciente acordou sem sinais de dor no pós-operatório imediato evitando estresse sistêmico, o que conferiu o bom resultado do protocolo analgésico instituído.

The patient (Caramel) canine, mixed breed, approximately 5 years old, weighing 26kg was seen at the Ame Vet veterinary clinic, with severe abdominal pain, apathy, anorexia, prostration. Blood tests, abdominal ultrasound and abdominal x-ray were performed according to the tests a suspicion of partial torsion of the stomach and splenomegaly with right displacement, in addition to gastritis and enteritis. It was decided by the clinic and surgeon to perform laparotomy and prophylactic gastropexy. The animal was previously medicated by the clinic that treated the animal for analgesia with methadone, tramadol and dipyrone two hours before the beginning of the surgical procedure, therefore, pre-anesthetic medications, anesthetic induction with propofol, and ketamine were not used, aiming to perform analgesia. Multimodal with continuous infusion of ketamine and fentanyl, that is, more than one different mechanism of action, acting synergistically and reducing dose-dependent adverse effects and monitoring hemostasis and patient parameters, presenting its efficacy and safety in intraoperative pain control. The parameters addressed were heart rate (HR), respiratory rate (RR), electrocardiographic tracing, Spo2, systolic blood pressure (SBP), mean arterial pressure (MAP), temperature and mucosal color, evaluated every 5 minutes. The parameters evaluated indicated good hemodynamic stability, safety and analgesia, with no need to change the doses established during the procedure. A reduction in the requirement of isoflurane to maintain the surgical plan can also be observed. The patient woke up without signs of pain in the immediate postoperative period, thus avoiding systemic stress. which conferred the good result of the analgesic protocol instituted.

Efeito da temperatura e do tempo de armazenamento de amostras de leite cru nos resultados das análises eletrônicas / Effect of temperature and time of storage of raw milk samples on eletronic analysis results

Objetivou-se com este trabalho avaliar os efeitos da temperatura e do tempo de armazenamento de amostras de leite cru refrigerado nos resultados das análises eletrônicas da qualidade do leite. Amostras de leite cru refrigerado foram coletadas de tanques de expansão de uso individual de fazendas localizadas na mesorregião Centro Goiano, no estado de Goiás, e armazenadas em quatro temperaturas diferentes (3°C, 11°C, 17°C e 25°C) durante 16 dias. Foram realizadas diariamente análises de contagem bacteriana total (CBT), contagem de células somáticas (CCS) e composição química. Os resultados obtidos foram submetidos à análise de variância em esquema de parcelas subdivididas no tempo em delineamento de blocos ao acaso, e as médias comparadas pelo teste de Duncan. Concluiu-se que as amostras destinadas à análise de CBT, adicionadas do conservante azidiol, podem ser analisadas por até 16 dias após a coleta, quando armazenadas em temperaturas de 3°C e 11°C, e por até 10 dias, quando armazenadas a 17°C. As amostras destinadas às análises de CCS e composição química, adicionadas do conservante bronopol, podem ser analisadas por até 16 dias após a coleta, quando armazenadas em temperaturas de 3°C e 11°C, e por até sete dias, quando armazenadas a 17°C.(AU)

The aim of this study was to evaluate the effects of temperature and storage time of cooled samples of raw milk on the results of milk quality electronic analysis. Refrigerated raw milk samples were collected from expansion tanks for individual use of farms located in the middle region of the state of Goiás, and stored at four different temperatures (3°C, 11°C, 17°C, and 25°C) for 16 days. Total bacterial count (TBC), somatic cell count (SCC), and chemical composition were performed daily. The results were submitted to analysis of variance in split plot design in randomized blocks, and the means were compared by Duncan test. We concluded that, when azidiol is added as preservative to samples for TBC, they can be analyzed up to 16 days after collection when stored at temperatures of 3°C and 11°C, and up to 10 days when stored at 17°C. Moreover, when bronopol is added as preservative, samples for SCC and chemical composition analysis can be stored for up to 16 days after collection when stored at temperatures of 3°C and 11°C, and for up to seven days when stored at 17°C.(AU)

Corn replacement by broken rice in meat-type quail diets

An experiment was conducted to evaluate the effects of broken rice inclusion as substitute for corn in the diet on the performance, carcass yield, and economic viability of meat-type quails between 7 and 49 days of age. A number of 288 quails was distributed according to a completely randomized design into six treatments with six replicates of eight birds each. Treatments consisted of increasing levels of broken rice (0, 20, 40, 60, 80 and 100%) in replacement of corn. Increasing levels of corn substitution by broken rice in the diet of 7- to 49-day-old meat-type quails did not affect feed intake, weight gain or feed conversion ratio (p>0.05). Relative to carcass traits, the inclusion of broken rice in the diets did not influence (p>0.05) dressing percentage or breast, leg (thigh+drumstick), liver, and gizzard yields. Moreover, feed cost per kilogram of live weight gain, cost index, and economic efficiency index were not influenced by the replacement of corn by broken rice in the diets. The performance, carcass traits and economic viability of broilers fed the different levels of broken rice inclusion were not different from the control group (p>0.05). These results indicate the economic viability of total replacement of corn by broken rice in the feeding of meat-type quails.

Radiologia do intestino delgado de cães por meio da técnica de duplo-contraste / Small bowel double-contrast study in dogs

Radiographic exams still the main form to evaluate small bowel in all its extension, and when surveyprojections are not diagnostic, barium series are used although its sensibility can be imitated by filledoverlapped loops, difficulting detailed mucosa visualization. The objective of this study was to adjust anexam technique with intestinal double-contrast, based on techniques used in the human medicine, whichresulted satisfactorily in the demonstration of the mucosal surface in the 30 dogs submitted to the exam.The double-contrast in the lumen was achieved by a combination of a positive contrast medium,recovering the mucosal surface, and a negative filling the lumen. Ambient air and carboximethylcelullosewere the negative contrast medium tested and both were radiographicaly similar.(AU)

Osteossíntese de úmero em pombos domésticos (Columba livia) associando-se pinos metálicos e polimetilmetacrilato intramedulares após osteotomia diafisária / Humerus osteosynthesis using intramedullary pins and polymethylmethacrylate in domestic pigeons (Columba livia)

Foram utilizadas 28 aves adultas, separadas aleatoriamente em quatro grupos. Os pombos foram anestesiados com isoflurano para a realização da osteotomia diafisária transversa do úmero direito. No grupo I, a osteossíntese foi realizada associando-se dois pinos de Kirschner e polimetilmetacrilato, intramedulares; no grupo II, os pinos de Kirschner foram substituídos por pinos de Schanz; no grupo III, foram utilizados apenas dois pinos de Kirschner; e, no grupo IV, apenas dois pinos de Shanz. Os tempos médios para a consolidação óssea foram de 29±4,04 dias no grupo I; 24±5,29 dias no grupo II; 33±3,74 dias no grupo III; e 32,9±5,21 dias no grupo IV. Foi observada migração dos pinos em 42,9 por cento dos animais do grupo I, em 0 por cento nos do grupo II, em 85,7 por cento nos do grupo III, e em 28,6 por cento nos do grupo IV. Em duas aves dos grupos I, III e IV notou-se incapacidade de voar. Os resultados demonstram que a associação de dois pinos de Schanz e polimetilmetacrilato, ambos intramedulares, é um método efetivo para osteossíntese de úmero em pombos domésticos (Columba livia), proporcionando rápida consolidação óssea e mínimas complicações.(AU)

Twenty-eight adult domestic pigeons (Columba livia) were randomly divided into four groups of seven birds each. Anesthesia was performed with isoflurane and oxygen, and an osteotomy of the right humerus midshaft was performed with an electric cutter. On the sequence, one of the following treatments was chosen: group I, two Kirschner pins and polymethylmethacrylate intramedullary; group II, two Schanz pins and polymethylmethacrylate intramedullary; group III, two Kirschner pins only; and group IV, two Schanz pins only. The mean time ± standard deviation for fracture healing was 29±4.04 days in group I; 24±5.29 days in group II; 33±3.74 days in group III; 32.9±5.21 days in group IV. Pin migration was observed in 42.9 percent of the group I animals, 0 percent of group II, 85.7 percent of group III, and 28.6 percent of group IV. Two pigeons of groups I, III, and IV presented flight incapability. The results suggest that two Schanz pins and polymethylmethacrylate intramedullary are an effective method of humeral ostheosynthesis in domestic pigeons (Columba livia), resulting in faster fracture healing with minimal complications.(AU)

Influência da temperatura de armazenamento e do sistema de utilização do tanque de expansão sobre a qualidade microbiológica do leite cru / Influence of the temperature of storage and of the system of utilization of the tank of expansion about the microbiological quality of the raw milk

Objetivou-se com o presente estudo avaliar a influência da temperatura de armazenamento e do sistema de utilização do tanque de refrigeração sobre a qualidade microbiológica do leite cru. Foram analisadas 1.215 amostras quanto a contagem bacteriana total (CBT), através da metodologia de citometria de fluxo. Nas amostras abaixo de 4,0ºC , entre 4,1 e 7,0ºC e acima de 7,0ºC a CBT média foi 2.733.000 UFC / ml, 3.641.000 UFC / ml e 5.687.000 UFC / ml, respectivamente. A CBT média das amostras provenientes de tanques coletivos foi 5.536.000 UFC / ml e das colhidas em tanques individuais foi 2.604.000 UFC / ml, sendo significativamente diferente (p<0,05). Observou-se que 70,21 por cento das amostras analisadas apresentaram CBT abaixo de 1.000.000 de UFC / ml. A baixa qualidade microbiológica das amostras sugere predominantemente a ocorrência de falhas na higiene de ordenha.(AU)

The purpose of this survey was to verify the effects of temperature and system of bulk tank utilization (community or single) on the microbiological quality of raw milk. The total bacterial count (TBC) of 1,215 bulk tank raw milk samples was determined by flow cytometry. On the samples with temperature under 4.0°C, between 4.1°C and 7.0°C, and higher than 7.0°C the TBC was 2,733,000 CFU /ml, 3,641,000 CFU / ml and 5,687,000 CFU/ml, respectively. The average of TBC on the samples taken from community and single bulk tanks was respectively 5,536,000 CFU /ml and 2,604,000 CPU/ ml, showing significant difference, p<0.05. 70,21% of the samples presented TBC under 1,000,000 CPU/ ml. The high TBC may be occurred due to several failures on the milking procedures. (AU)
