Resumo
Em animais de companhia, as feridas traumáticas ocorrem com elevada frequência e o seu maneio geralmente está associado e elevados custos económicos. Porém, o seu acompanhamento adequado permite alcançar resultados bastante positivos e economizar a longo prazo.
Com o presente relatório de estágio, pretendeu-se realizar uma revisão de literatura sobre as recomendações mais atuais ao nível da abordagem e maneio das feridas traumáticas. Também se pretendeu avaliar o penso de hidrogel de caseína ácida impregnado com Octiset®, quanto ao seu contributo para maior celeridade do processo de cicatrização. Para tal, procedeu-se à aplicação deste tipo de penso em 3 casos clínicos, cujo encerramento foi efetuado por segunda intenção.
O penso em estudo foi desenvolvido pelo Centro de Química Estrutural no Instituto de Ciências Moleculares e Departamento de Engenharia Química do Instituto Superior Técnico da Universidade de Lisboa. O seu desenvolvimento permitiu a libertação de propriedades antibacterianas de forma controlada, durante 48 horas. São pensos hemocompatíveis, não citotóxicos, nem irritantes, possuem propriedades elásticas e de desbridamento autolítico. Adicionalmente, considerando que os componentes necessários para fabrico deste penso são de baixo custo, os mesmos incluem vantagens quanto à sua disponibilidade comercial futura.
Para cada ferida foi efetuada a medição e documentação objetiva da sua geometria e progressão ao longo do tempo, de modo a analisar a taxa de redução por contração e epitelização. Deste modo verificou-se uma relação entre a gravidade do dano tecidual e o tempo decorrido até à resolução completa das lesões.
Embora o número de casos analisados não permita tirar conclusões, identificou-se um potencial de melhoria significativa do processo de cicatrização pela utilização deste tipo de penso. No último caso, foi possível verificar que o processo de cicatrização pela utilização de um penso tradicional, revelou ser menos célere (cerca de 3 vezes inferior) quando comparado com a utilização do penso em estudo.
Sugere-se o desenvolvimento de estudos futuros, de modo a melhor comprovar a eficácia e rapidez do processo de cicatrização obtida com a aplicação dos pensos em estudo.

In small animals, traumatic wounds occur with high frequency and their management usually involves heavy expenses. However, proper management of traumatic wounds can achieve very positive results and save money in the long term. The aim of this internship report was to perform a literature review of the approach and management of the most accepted traumatic wounds nowadays. It was also intended to evaluate the acid casein hydrogel dressing loaded with Octiset® for its contribution to the faster healing process. For this purpose, this type of dressing was applied in 3 clinical cases, which were closed by secondary intention. The dressing under study was developed by the Centre for Structural Chemistry at the Institute of Molecular Sciences and Department of Chemical Engineering of the Instituto Superior Técnico of the University of Lisbon. Its development allowed for the release of antibacterial properties in a controlled manner for 48 hours. These dressings are hemocompatible, non-cytotoxic, non-irritating, have elastic and autolytic debridement properties. Additionally, considering that the components needed to manufacture this dressing are low cost, they have advantages regarding their future commercial availability. For each wound, measurement and objective documentation of its geometry and progression over time was performed to analyze the rate of shrinkage reduction and epithelialization. In this way, a relationship was found between the severity of tissue damage and the time elapsed until complete resolution of the lesions. Although the number of cases analyzed does not allow conclusions to be drawn, a potential for significant improvement in the healing process by using this type of dressing was identified. In the last case, it was possible to verify that the healing process with the use of a traditional dressing was less rapid (about 3 times less) when compared to the use of the dressing under study. We suggest the development of future studies, in order to better prove the effectiveness and speed of the healing process obtained with the application of the dressings under study.
