AI Article Synopsis
- - The study aimed to identify factors that predict the need for red blood cell transfusions (RBCT) after cardiac surgery, using a group of 323 adults who underwent the procedure. - Researchers collected data on various risk factors related to excessive bleeding and analyzed the relationship between these factors and RBCT using statistical methods. - Key findings indicated that lower weight was a significant predictor of RBCT, along with several other factors such as decreased platelet and hemoglobin levels, and longer anesthesia duration.
Article Abstract
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.
