A lavagem traqueal e a lavagem broncoalveolar como métodos de diagnóstico da doença respiratória em equinos

Abstract

ABSTRACT - The tracheal wash and bronchoaveolar lavage as methods used in the diagnosis of equine respiratory disease - The respiratory disease is one of the most important cause of poor athletic performance in race horses worldwide. Nowadays there is a large number of tools and ancillary diagnostic techniques that can be used to perform an accurate examination of the upper and lower respiratory tract. It is important for all the veterinarians to know the major indications, the information that can be obtained from them and their correct use in order to achieve a specific diagnosis. The main goal of this work was to develop and to apply a protocol for the sample collection, processing and evaluation of respiratory secretions suitable for the veterinary hospital where this work was developed. Secondarily we intended to verify the cells retrieved by tracheal wash and bronchoalveolar lavage in horses without a medical history or symptoms of respiratory disease and, thus conclude on the importance and indications of these techniques in the study of respiratory disease. With this work we noted the predominance of globet cells, ciliated columnar cells and alveolar macrophages in samples obtained by tracheal wash. Two of the five horses were diagnosed with pharyngeal lymphoid hyperplasia in the endoscopic examination but they had no symptoms of respiratory disease at the physical examination, highlighting the importance of the use of all the information gathered during the diagnosing process.

A doença respiratória é uma das causas mais importantes da má performance atlética em cavalos de desporto em todo o mundo. Actualmente estão disponíveis um grande número de ferramentas e exames complementares que permitem uma avaliação minuciosa do aparelho respiratório. É importante para os veterinários conhecer as principais indicações, as informações passíveis de ser obtidas através do uso correcto destes meios complementares para se chegar ao diagnóstico definitivo específico. O objectivo geral deste trabalho consistiu na implementação e desenvolvimento de um protocolo para a colheita, processamento e avaliação das secreções respiratórias em equinos adequado para o funcionamento do hospital veterinário onde este trabalho foi desenvolvido. Secundariamente pretendeu-se verificar os tipos celulares obtidos na lavagem traqueal e na lavagem broncoalveolar em equinos sem história clínica e sinais de doença respiratória e, deste modo inferir sob a importância e aplicabilidade de ambas as técnicas no estudo da patologia respiratória. Com este trabalho constatámos a predominância das células globulares, células colunares ciliadas e de macrófagos alveolares na lavagem traqueal. Dois dos cinco equinos seleccionados para colheita apresentaram hiperplasia linfóide folicular diagnosticada através da endoscopia não tendo demonstrado nenhuma sintomatologia no exame físico salientando a importância da conjugação de todas os dados recolhidos durante todo o processo de diagnóstico.
