Resumo: At the School of Veterinary Medicine and Animal Science, University of São Paulo, Brazil, preliminary surgical training involving live animals has been replaced by the use of embalmed canine cadavers. This study aimed to improve the embalming technique based on the modified Larssen solution by altering the original formulation. Twenty-four canine corpses obtained according to the norms and resolutions described by the animal research ethics committee were used in this study. The cadavers were randomly allocated to two groups, G1 and G2, and treated with modified Larsen solution containing 20% and 10% formalin, respectively. The Larssen solution used in G1 contained a higher volume of distilled water and higher formalin concentration than the one used in G2. Cadavers were used in hands-on surgical training labs for four weeks. The following evaluation criteria were considered: general appearance, muscle tissue color, tissue texture/consistency, joint flexibility, odor development, and skin integrity in the abdominal and other regions involved in surgical training. The cadavers in both groups showed good general appearance and retained satisfactory organoleptic properties for surgical training throughout the experimental period. There was no significant difference between the groups treated with 20% or 10% modified Larssen solution (p > 0.05; chi-square test). The present findings were considered positive, because the dilution of the original formulation exhibited similar efficacy and required smaller amounts of chemicals, thus reducing the formulation cost.Keywords: alternative methods; teaching; modified Larssen solution

O objetivo deste estudo foi melhorar a técnica de embalsamamento baseada na solução Larssen modificada através de modificações em sua formulação original. Vinte e quatro cadáveres caninos obtidos conforme as normas e resoluções descritas pelo comitê de ética em pesquisa animal foram utilizados neste estudo. Os cadáveres foram divididos aleatoriamente em dois grupos (G1 ou G2) e tratados com solução modificada de Larssen contendo 20% e 10% de formalina, respectivamente. A solução de Larssen usada em G1 continha um maior volume de água destilada e maior concentração de formalina em comparação com o utilizado em G2. Os cadáveres foram utilizados no laboratório de treinamento cirúrgico prático durante quatro semanas. Foram considerados os seguintes critérios de avaliação: aparência geral, cor do tecido muscular, textura/consistência do tecido, flexibilidade das articulações, desenvolvimento de odor e integridade da pele na região abdominal e outras regiões envolvidas no treinamento cirúrgico. Os cadáveres em ambos os grupos apresentaram boa aparência geral e mantiveram as propriedades organolépticas satisfatórias para treinamento cirúrgico ao longo do período experimental. Os cadáveres tratados com 20% ou 10% de solução modificada de Larssen não diferiram significativamente (p> 0,05, teste de qui-quadrado). Os resultados deste estudo foram considerados positivos, visto que a diluição da formulação original produziu eficácia semelhante e, no entanto, exigiu quantidades menores de produtos químicos, diminuindo o custo da formulação.Palavras-chave: métodos alternativos; ensino; solução de Larssen modificadaUniversidade Federal de Goiás2019-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/50266Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 20 (2019): Continuous publication; 1-11Ciência Animal Brasileira / Brazilian Animal Science; v. 20 (2019): Publicação contínua; 1-111809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/vet/article/view/50266/33302https://revistas.ufg.br/vet/article/view/50266/33303Copyright (c) 2019 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessZanuto, Erika De Brito MarcoSouza, Maria Cláudia Campos Mello Inglez deRibeiro, Antonio Augusto Coppi MarcelMatera, Julia Maria2023-03-23T18:49:21Zoai:ojs.revistas.ufg.br:article/50266Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:20.650169Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
