    Predictors of red blood cell transfusion after cardiac surgery: a prospective cohort study
    (2015) LOPES, Camila Takao; BRUNORI, Evelise Helena Fadini Reis; CAVALCANTE, Agueda Maria Ruiz Zimmer; MOORHEAD, Sue Ann; LOPES, Juliana de Lima; BARROS, Alba Lucia Bottura Leite de
    Objective: To identify predictors of red blood cell transfusion (RBCT) after cardiac surgery. Method: A prospective cohort study performed with 323 adults after cardiac surgery, from April to December of 2013. A data collection instrument was constructed by the researchers containing factors associated with excessive bleeding after cardiac surgery, as found in the literature, for investigation in the immediate postoperative period. The relationship between risk factors and the outcome was assessed by univariate analysis and logistic regression. Results: The factors associated with RBCT in the immediate postoperative period included lower height and weight, decreased platelet count, lower hemoglobin level, higher prevalence of platelet count < 150x10(3)/mm(3), lower volume of protamine, longer duration of anesthesia, higher prevalence of intraoperative RBCT, lower body temperature, higher heart rate and higher positive end-expiratory pressure. The independent predictor was weight <66.5Kg. Conclusion: Factors associated with RBCT in the immediate postoperative period of cardiac surgery were found. The independent predictor was weight.

    Excessive bleeding predictors after cardiac surgery in adults: integrative review
    (2015) LOPES, Camila Takao; SANTOS, Talita Raquel dos; BRUNORI, Evelise Helena Fadini Reis; MOORHEAD, Sue A.; LOPES, Juliana de Lima; BARROS, Alba Lucia Bottura Leite de
    Aims and objectivesTo integrate literature data on the predictors of excessive bleeding after cardiac surgery in adults. BackgroundPerioperative nursing care requires awareness of the risk factors for excessive bleeding after cardiac surgery to assure vigilance prioritising and early correction of those that are modifiable. DesignIntegrative literature review. MethodsArticles were searched in seven databases. Seventeen studies investigating predictive factors for excessive bleeding after open-heart surgery from 2004-2014 were included. ResultsPredictors of excessive bleeding after cardiac surgery were: Patient-related: male gender, higher preoperative haemoglobin levels, lower body mass index, diabetes mellitus, impaired left ventricular function, lower amount of prebypass thrombin generation, lower preoperative platelet counts, decreased preoperative platelet aggregation, preoperative platelet inhibition level >20%, preoperative thrombocytopenia and lower preoperative fibrinogen concentration. Procedure-related: the operating surgeon, coronary artery bypass surgery with three or more bypasses, use of the internal mammary artery, duration of surgery, increased cross-clamp time, increased cardiopulmonary bypass time, lower intraoperative core body temperature and bypass-induced haemostatic disorders. Postoperative: fibrinogen levels and metabolic acidosis. ConclusionsPatient-related, procedure-related and postoperative predictors of excessive bleeding after cardiac surgery were identified. Relevance to clinical practiceThe predictors summarised in this review can be used for risk stratification of excessive bleeding after cardiac surgery. Assessment, documentation and case reporting can be guided by awareness of these factors, so that postoperative vigilance can be prioritised. Timely identification and correction of the modifiable factors can be facilitated.
