Abstract
Objective: to determine whether there is an association between knowledge of the nursing professionals about blood transfusion and the variables related to the professional aspects. Method: this is an observational, cross-sectional and quantitative study, carried out at a large general teaching hospital. The sample consisted of 209 nursing professionals, obtained by simple random sampling. For data collection, a checklist was used. In the univariate analysis, descriptive statistics and central trend and dispersion measures were used. In the bivariate analysis, Student's t-Test, analysis of variance and Pearson's correlation were used. To determine the predictors, multiple linear regression was applied. The Institutional Review Board (Opinion number 2434) approved the study. Results: the overall average knowledge score was 52.66%; in the Pre-transfusion Step, it corresponded to 53.38%; in the Transfusion Step 51.25% and, in the Post-transfusion Step, 62.68%. The factors related to knowledge were professional category and received training and/or guidance to accomplish the transfusion process (p<0.01). Conclusion: this study showed the influence of training and guidance on the knowledge and provided a diagnosis to identify the professionals' difficulties regarding the transfusion process.

The average age of professionals was 38.2 years with a high concentration in the age group between 32 and 41 years. These data corroborate the other studies in which the mean age was between 36.8 and 37.9 years, with the highest concentration in the age group between 31 and 40 years of age[2,3,10,11,12] .With respect to gender, females prevailed, corroborating the results found in the literature[2,3,6,11,13]
This study highlighted the lack of knowledge of the nursing team professionals on blood transfusion, as well as the influence of training and guidance on knowledge
Summary
Blood therapy plays an important therapeutic role, being used to treat various health problems. Despite presenting risks by involving biological products of human origin, blood transfusion is an essential part of health care, promotion and recovery[2,3]. In Brazil, the standardization of transfusion procedures is determined by Resolution number 57 of the Board of Directors (RBD), issued on December 16th 2010, which determines the Health Regulations[4], and by Ordinance number 1353, published by the Ministry of Health (MH) on June 13th, 2011. The latter determines the Technical Regulations for services related to the cyclical production of human blood and its components and transfusion procedures. These regulations establish rules that blood transfusion professionals need to know and follow[5]
