The aim of this pilot test was to test a new self-locking resorbable implant for hilum occlusion during a video-assisted thoracoscopic lung lobectomy in a surviving pig model. Once the thoracic cavity was assessed and structures identified, the right middle lobe and its respective hilum were exposed. The implant was introduced with a semiclosed loop through a working channel and positioned around the pulmonary lobe. Occlusion was performed with a conventional Crile forceps and a laparoscopic Kelly forceps. Lobe section was done with laparoscopic Metzenbaum scissors and tissue removal through the dorsal access. No signs of pneumothorax or bleeding were observed during a 60-day follow-up. Necropsy findings showed minimal pleuritis in caudal access and in the lobar stump. A granulomatous formation was found around a dense, amorphous material, which was identified as remains of a small part of the implant. Histopathological findings showed signs of a chronic healing process without other alterations. The resorbable implant LigaTie appears to exhibit similar handling and application characteristics during surgery as nonsurgical tie wraps. The resorbable implant avoids the uncontrolled substances not suitable for implants of conventional ties. The results of this pilot test suggested the resorbable implant's mechanical properties provided effective tissue support to complete the healing of the pulmonary hilum.

Recurrent prolapses did not recur in the 2 months of postoperative observation.

RESUMO:A orquiectomia é utilizada para esterilizar cavalos de baixo valor genético, melhorando o manejo. Pode ser realizada com anestesia geral ou local, em decúbito dorsal ou em estação. Algumas complicações podem ocorrer como hemorragia, edema, infecção e peritonite. O objetivo deste trabalho foi comparar o tempo cirúrgico, a ocorrência de complicações pós-operatórias e o tempo de internamento de cavalos submetidos à orquiectomia eletiva por meio de três diferentes técnicas empregadas por alunos e residentes do curso de medicina veterinária. Foram utilizados 25 cavalos, sendo separados em três grupos: grupo 1 (EMA, n=8), submetidos à orquiectomia bilateral em posição quadrupedal, bloqueio local e sedação, hemostasia com emasculador onde a túnica vaginal foi mantida aberta; grupo 2 (BRA, n= 8), submetidos à orquiectomia bilateral em posição quadrupedal, bloqueio local e sedação, hemostasia com duas abraçadeiras de náilon de 2,5mm e túnica vaginal mantida aberta; grupo 3 (ING, n=9), submetidos à orquiectomia bilateral em decúbito dorsal e anestesia geral, hemostasia com emasculador, e túnica vaginal e pele suturadas. O tempo médio dos procedimentos foi de 16,3±2,5min no grupo EMA, 14,5±1,6min no grupo BRA e 64,4±16,6min no grupo ING. No pós-operatório dos animais não foi observado sangramento no grupo ING; no grupo EMA houve sangramento grau 2 e no grupo BRA houve sangramento grau 1. O tempo médio de internamento foi de 22,7±3,2 dias, 20,75±0,7 dias e 10,7±4,5 dias respectivamente. A orquiectomia bilateral sob efeito de anestesia geral e fechamento da túnica vaginal, demanda maior tempo cirúrgico quando comparada às orquiectomias realizadas com os cavalos em posição quadrupedal e manutenção da túnica aberta. Porém, não foram observadas complicações pós-operatórias nos animais castrados com essa técnica, diminuindo assim o tempo de internação hospitalar e os cuidados pós-operatórios.Palavras-chave: castração; cirurgia; equinos ABSTRACT: Orchiectomy is used to neuter low genetic value horses, improving management. Can be performed under general or local anesthesia, supine or quadrupedal position respectively. Some complications can occur such as bleeding, swelling, infection and peritonitis. The aim of this study was to compare the surgical time, the occurrence of postoperative complications and length of hospital care of horses undergoing elective orchiectomy through three different techniques used by veterinary school students and residents. 25 horses were selected, divided into three

The measurement of serum parameters during general anesthesia procedures are subject to variations due to differences in protocol, splenic storage, and by the instituted fluid therapy. The aim of this study was to assess the hematocrit changes promoted by controlled fluid therapy and general anesthesia. Six mongrel female dogs underwent an anesthetic protocol with acepromazine (0.03 mg kg -1 ) and tramadol (5 mg kg -1 ) for premedication, induction with propofol (3 mg kg -1 ), and maintained with isoflurane and mechanical ventilation for 120 minutes. After induction, they were infused with 10 ml kg hr -1 of Ringer's lactate solution. Hematocrit measurements were performed from the start until 72 hours from anesthesia and evaluated statistically to check if there were significant changes over time. The fluid therapy, the acepromazine and propofol in the anesthetic protocol promotes a significant reduction of hematocrit up to four hours after general anesthesia. Key words: Packed cell volume, crystalloids, acepromazine, propofol, bleeding ResumoA mensuração de parâmetros séricos durante procedimentos dependentes de anestesia geral são passíveis de variações devido a diferenças do protocolo utilizado, armazenamento esplênico e também da fluidoterapia instituída. O objetivo deste trabalho foi avaliar o hematócrito buscando evidenciar as alterações flutuantes promovidas por fluidoterapia controlada e anestesia geral em cães submetidos a ovariohisterectomia laparoscópica. Seis cadelas sem raça definida foram submetidas a um protocolo anestésico com acepromazina (0,03 mg kg -1 ) e tramadol (5,0 mg kg -1 ) como medicação pré-anestésica, indução com propofol (3,0 mg kg -1 ) e mantidas com isoflurano e ventilação mecânica durante 120 minutos. Após a indução, receberam a infusão de 10,0 ml kg hr -1 de solução Ringer com lactato. Foram realizadas aferições de hematócrito do início (ou antes?) até 72 horas após a anestesia, sendo avaliadas 1 Discente, Programa de Pós-graduação em Ciências Veterinárias, Universidade Federal do Paraná, UFPR, Curitiba, PR.

RESUMO:Afecções dentárias são as principais enfermidades da cavidade oral de equinos, podendo estar relacionadas à dieta e ao escore corporal. Objetivou-se neste estudo avaliar as desordens dentárias, escore corporal e o manejo alimentar que cavalos de tração da região metropolitana de Curitiba apresentam, e verificar se há correlação entre eles. Foram avaliados 64 equinos, através de exame clínico e avaliação odontológica. Destes, 52 apresentaram escore corporal adequado, 54 apresentaram apenas uma alteração dentária e 27 apresentaram duas ou mais, sendo a presença de caninos longos a alteração mais encontrada, observada em 20 cavalos. Pontas de esmalte, ganchos, rampas, presença do dente primeiro pré-molar, fraturas dentárias, cálculos dentários, degraus e ausência de dentes foram outras alterações encontradas. Os principais componentes da dieta desses cavalos de tração são: pasto, capim picado, farelo de trigo, milho e restos de comida. Através do Teste de Correlação de Spearman verificou-se ausência de significância estatística na correlação entre a dieta, as alterações dentárias e o escore corporal. Conclui-se com este estudo que os cavalos carroceiros da região metropolitana de Curitiba apresentam baixa prevalência de problemas dentários, os quais não são influenciados pela dieta e não acarretam em prejuízos ao seu escore corporal. Palavras-chave: alterações dentárias; carroceiro; dieta; escore corporal; equinos ABSTRACT: Dental diseases are the main affections of the horse oral cavity and may be related to diet and body condition. The aim of this study was to evaluate these disorders, the body condition and feeding management of draft horses from Curitiba metropolitan areas, checking if there is a correlation between them. Sixty-four horses were evaluated by clinical examination and dental evaluation. From those 52 had adequate body condition, fifty-four had only one tooth affection and 27 had two or more. The presence of wolf teeth the most frequent alteration, observed in 20 horses. Enamel ends, hooks, ramps, presence of the first premolar tooth, fractures, dental calculi, steps and missing teeth were other alterations. The main components of the diet were grass, chopped grass, wheat bran, and corn and food debris. Using the Spearman's correlation test there was no statistically significance between diet, dental change and body condition. This study concludes that the draft horses from Curitiba metropolitan areas have a low prevalence of dental problems, which are not influenced by diet and do not result in damage to body condition.

Background: Pulmonary aspiration of gastric content can result in intraoperative and postoperative complications, such as regurgitation, gastro-esophageal reflux and esophagitis. There are variations among authors about the ideal period of solid and liquid fasting. Determination of the appropriate amount of food abstinence in surgical patients is important, because of the metabolic disorders that interfere in response to anesthetic protocol or surgical intervention. Thereby, this research aimed to evaluate the appropriate period of fasting for elective anesthesia and surgical procedures in cats, by analysis of gastric emptying time based on the daily energy requirement.Materials, Methods & Results: Seven cats of mixed breed, health and with an average weight of 2.857 ± 0.3780 were evaluated by gastroscopy for the presence of food and obtaining tissue samples. To evaluate the gastric emptying time, dry and moist food were offered at two different times, 8 h and 4 h before each evaluation, with an interval of seven days between each food treatment (dry and moist). There was no significant difference in all biochemical parameters evaluated (cholesterol, glucose, and lactate) in both fasting times and food types (P > 0.05). All animals underwent gastric biopsy for histological evaluation and urease test, to discard morphological changes. After 4 h it was observed dry food in all cat’s stomach, however just five cats presented food in their stomach after eight hours. In other hand all the animals, which ate moist food, did not present any gastric content after four hours and eight hours of feeding. Gastric mucosa were considered normal in all cats with moderate amount of Helicobacter sp.Discussion: The difficulty of a consensus on the fast time in cats, and the great variability of the emptying time according to the feeding type, makes this study useful as basis for future studies on fasting with wet food, as well as providing immediate clinical application in surgical routine. Only a moderate gastritis related to helicobacter sp. was detected, but even healthy animals can carry Helicobacter sp.  Four h of fasting time if feed the patient with 80% humidity ration improve anesthetic security of the patient with typical biochemical values. As shown, the appropriate preoperative fasting directly implies on decrease in the number of complications related to full stomach. Thus, always should take into account the possibility to perform fast in an appropriate period to prevent vomiting and aspiration, without the risk of hypoglycemia benefiting the patient and reassuring the anesthesiologist, especially in situations requiring urgent or emergency intervention. As observed through endoscopy, even eight hours of fasting with dry feed is inappropriate due to significant gastric volume of food in almost all cats. This suggests that prolonged preoperative fasting is no guarantee of low stomach volume. Wet feed can be an option for elderly and debilitated patients requiring surgical intervention within a short period of fasting. The time varies with type and volume of food that is variable according patients and different species and digestive conditions. The research were conducted with none complications. By means, this experiment it was concluded that the fasting time of 4 h with 80% humidity moist food allows complete gastric emptying without any complication.
