Resumo: The main purpose of this study is to determine a formula for the calculation of the volume of ultrafiltrate to be extracted by Modified Ultrafiltration (MUF) from adult patients undergoing heart surgery. The target population includes 489 cases corresponding to theheart surgeries performed from January 2003 to December 2005 meeting the inclusion and exclusion criteria that have been established. It is a retrospective, correlational, and quantitative study that takes a deductive approach, with the studied variables having been collected from the cardiovascular perfusion reports of the Cardiothoracic Surgery Unit of Hospital de Santa Marta, EPE. The relation between the variables being studied was studied by means of correlation and linear regression models. The model obtained to define the formula of calculation wanted takes the existent correlation as a base between the volume to take out for MUF and the body surface of the patient when there is this the only one of three studied models that demonstrate a dependence, still weak that, between the variables, and is expressed through the formula: Y=545,4.X3, in that Y, is the volume take out for MUF and X is the value of the body surface of each patient and is representative only for 4% of the population in the study. The average increase of hemoglobin value after MUF is 1.9±1.09g/dl, which evidences the efficacy of this technique in obtaining hemoconcentration.

A população-alvo é constituída por 489 casos relativos às cirurgias cardíacas realizadas entre Janeiro de 2003 e Dezembro de 2005, que cumprem os critérios de inclusão e exclusão definidos. Trata-se de um estudo retrospectivo, do tipo correlacional quantitativo com abordagem dedutiva, em que as variáveis estudadas foram obtidas através da consulta dos relatórios de perfusão cardiovascular do Serviço de Cirurgia Cardiotorácica do Hospital de Santa Marta, EPE. A relação entre as variáveis em estudo foi analisada através da correlação e modelos de regressão linear. O modelo obtido para definir a fórmula de cálculo desejada tem por base a correlação existente entre o volume a retirar por UFM e a superfície corporal do doente, sendo este o único dos três modelos estudados que demonstra uma dependência, ainda que fraca, entre as variáveis, e exprimindo-se através da fórmula Y=545,4.X3, em que Y é o volume a retirar por UFM e X é o valor da superfície corporal de cada doente, e sendo representativo apenas para 4% da população em estudo.” O aumento médio de hemoglobina pós-UFM é de 1,9±1,09g/dl, o que traduz eficácia da técnica na obtenção de hemoconcentração. Escola Superior de Tecnologia da Saúde de Lisboa (Instituto Politécnico de Lisboa)2008-05-15info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.25758/set.64https://doi.org/10.25758/set.64Saúde e Tecnologia; No. 01 (2008): Maio 2008; 42-46Saúde & Tecnologia; N.º 01 (2008): Maio 2008; 42-461646-9704reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journals.ipl.pt/stecnologia/article/view/773https://journals.ipl.pt/stecnologia/article/view/773/666Direitos de Autor (c) 2023 Saúde & Tecnologiainfo:eu-repo/semantics/openAccessGonçalves, Ana SofiaFigueira, Maria InêsFranco, Paulo JorgeRaposo, Susana Martins2023-06-02T08:30:24Zoai:journals.ipl.pt:article/773Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T17:56:04.325111Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
