- W1506665104 abstract "Introduction: Patients who undergo a total hip arthroplasty are still in a high risk of severe anemia that leads to a perioperative blood transfusion. As a first step to decrease the frequency of transfusions, it is necessary to determine those clinical conditions associated with this outcome. The purpose of this study was to determine the risk factors associated with perioperative blood transfusion. Methods: 230 total hip arthroplasties were retrospectively evaluated. Relevant clinical conditions were measured in the group of patients who needed transfusion as well as in the group that did not. Data were analysed through univariate and multivariate analysis. Results: 106 patients required transfusion which accounts for 46.1%. Female gender, a low preoperative hemoglobin level and an elevated arterial blood pressure were identified as risk factors for perioperative blood transfusion. These results were significant for both univariate and multivariate analysis. Other factors such as preoperative diagnosis, weight, bone mass index, comorbidities and type of anesthesia showed non-significant differences. Discussion: Our results encourage surgeons to focus on preoperative conditions. Specifically, hemoglobin blood levels and arterial blood pressure should be improved in order to reduce perioperative transfusion rates." @default.
