Abstract(s)
As transfusões sanguíneas são cada vez mais comuns na prática de clínica de animais de companhia. A disponibilidade de diferentes produtos, tais como testes rápidos de tipificação sanguínea e a disponibilidade de produtos sanguíneos disponíveis no mercado facilitam a sua realização.
O presente estudo teve como objetivo caracterizar uma população de cães e gatos submetidos a terapêutica transfusional com sangue total ou concentrado de eritrócitos, em seis centros de atendimento médico veterinários de Portugal, entre Março de 2014 e Março de 2019. Foram recolhidos dados referentes à caracterização dos animais, ao número de transfusões, origem e tipo de componentes administrados, à tipificação, aos principais motivos da transfusão, à sobrevivência, ao número de dias de internamento e à variação do valor do hematócrito após a realização das transfusões sanguíneas.
No presente estudo foram analisados 116 animais, dos quais 59 cães e 57 gatos, aos quais foram realizadas transfusões sanguíneas de sangue total ou de concentrados de eritrócitos. A maioria dos animais não foi tipificada (63,8%) previamente à transfusão, sendo que, dos animais tipificados a maioria dos gatos (96,2%) pertencia ao tipo sanguíneo A, e a maioria dos cães (75,0%) ao DEA 1 positivo. A maioria dos animais sobreviveu após a transfusão (77,2% gatos e 64,4% cães). A sobrevivência dos gatos após a transfusão foi influenciada de forma significativa pela idade, e nos cães pela idade e origem do sangue, sendo que os animais mais velhos apresentaram menor sobrevivência, e os animais transfundidos com componentes provenientes do banco de sangue tiveram uma maior sobrevivência. A sobrevivência pode ter sido influenciada por outros fatores tais como o motivo/doença subjacente do animal. A média de hematócrito pré-transfusional nos gatos (11,8%) foi mais baixa que nos cães (16,7%), pela maior capacidade de adaptação dos primeiros. Nos cães, o aumento médio do hematócrito após a transfusão foi de 9,0%, próximo dos 10% conforme recomendado pela literatura consultada, enquanto que nos gatos foi de 6,2%. Não foram registadas reações transfusionais.
Blood transfusions are becoming increasingly common in companion animal clinical practice. The availability of different products, such as rapid blood typing tests and the availability of blood products available on the market facilitate blood transfusions. The present study aimed to characterize a population of dogs and cats submitted to transfusion therapy at six veterinary medical centres from Portugal between March 2014 and March 2019. Data were collected on the characterization of the animals, the number of transfusions, origin and type of components administered, typing, main reasons for transfusion, survival, number of days of hospitalization and increase in haematocrit value after blood transfusion. In the present study, 116 animals were analysed, of which 59 dogs and 57 cats, in which blood transfusions of whole blood or erythrocyte concentrates were performed. Most of the animals were not typified prior to transfusion (63,8%), and most typified animals belonged to group A, in cats (96,2%), and to DEA 1.1. positive in dogs (75,0%). After the transfusions, most of the animals survived (77,2% cats e 64,4% dogs). The survival of cats after transfusion was significantly influenced by age, and in dogs by age and origin of blood, being that older animals had lower survival and animals transfused with blood bank components had a higher survival. Survival may have been influenced by other factors such as the animal's underlying cause / disease. The mean pre-transfusional haematocrit in the cats (11,8%) was lower than in the dogs (16,7%), due to the greater adaptability of the former. In dogs, the haematocrit increase was 9,0%, close to 10% as recommended by the literature, while in cats was 6,2%. No transfusion reactions were recorded.
