Abstract

History and objectives: Many factors influence the indication of nalmente. blood transfusion for critical ill patients. Nevertheless there are Em relação a outros estudos, houve menor prevalência few studies concerning the transfusion of blood components in de pacientes cirúrgicos e maior tempo médio de internação patients under intensive care. This study is aimed at analyzing the na UTI por paciente admitido. Isto sugere predomínio de rate and the transfusion incidence-density of red blood cells (RBC) transfusões por doenças crônicas ou de evolução arrastada, in an Intensive Care Unit (ICU) of the University Hospital of Federal University of Santa Catarina and to describe the clinical onde baixos níveis de hemoglobina seriam o critério de trans- criteria and the haemoglobin values applied to indicate fusão mais esperado. transfusions. Method: For this study, patients admitted into the Estudos recentes contestam a utilização do nível de ICU between January 2003 and December 2004 were included. hemoglobina como parâmetro isolado na indicação de CH e Results: A total of 654 patients were studied.
