Intraoperative and immediate postoperative transfusion: Clinical-hematological profile of transfunded patients in a university hospital.

• Significant Transfusion Rates: 25.44% of patients undergoing elective surgeries required intraoperative or immediate postoperative blood transfusions, indicating a critical need for blood reserve management in surgical settings. • Pre-Surgical Hemoglobin as a Predictor: Patients with higher pre-surgical hemoglobin levels were less likely to need transfusions, underscoring the importance of pre-operative anemia management. • Diverse Surgical Needs: The study found a higher prevalence of transfusions in oncological surgeries compared to other types, highlighting varying blood component needs across surgical categories. • Blood Utilization Efficiency: The research revealed inefficiencies in blood utilization, with a high ratio of requested to transfused blood units, particularly in red blood cell concentrates. • Trend Towards Restrictive Transfusion Practices: The study aligns with global trends towards more restrictive blood transfusion practices, especially in cancer surgeries where transfusion probabilities are higher. The transfusion practice by surgery blood reserve, varied among services, must be performed through the rational and restrictive use of blood components because it is a scarce and expensive resource for health care services. Analyze the use of blood products for surgery blood reserve by means of the study of the clinical-hematological profile of patients submitted to intraoperative and immediate postoperative transfusions. This was an observational, cross-sectional, and retrospective study, conducted by collecting biological, operational, and laboratory variables, involving 680 patients at a university hospital who had elective surgery with surgery blood reserve request sent during the period from October 2021 to October 2022. The overall transfusion rate was 25.44%, and the mean preoperative hemoglobin level of transfused patients was 9.74 ± 2.50 g/dL, with the mean number of transfusions packed red blood cell units was 1.58 ± 0.77. Patients with higher preoperative hemoglobin levels were less likely to have transfusion (p < 0.001) and patients who had surgical oncologic were more likely to require transfusion (p = 0.048). The transfusion rate of packed red blood cells and platelets concentrates, compared to what was requested, was 15.86% and 5.82%. There is a tendency of transfusions to follow restrictive models, with higher transfusion probability in surgical oncologic. Furthermore, there should be more a conscise use of the surgery blood reserves request. [ABSTRACT FROM AUTHOR]
