SUMMARY
In order to identify opportunities to enhance blood‐sparing strategies, we studied blood‐transfusion practices in patients undergoing scheduled major surgery in Spain. This prospective, multicenter epidemiological study involved 20 Spanish hospitals. We recorded the pre‐ and postoperative hemoglobin concentrations, the estimated and calculated blood loss, the number of patients transfused and the blood‐sparing techniques used. A total of 359 patients from 18 centers were included in the analysis. Mean preoperative hemoglobin concentration was 13.7 ± 1.6 g/dL. In 29% of the patients, preoperative hemoglobin concentration was lower than 13 g/dL. All surgeries combined, mean estimated blood loss was 845 ± 659 mL and mean calculated blood loss 1722 ± 1021 mL. The percentage of patients transfused with allogeneic blood was 28.4% altogether and ranged from 47.2% in cardiac surgery patients to 4.5% in plastic‐maxillofacial surgery patients. Blood‐sparing techniques were used only in 70 patients (19.4%). For a large percentage patients who underwent scheduled major surgery, blood transfusion was needed and perioperative blood loss was underestimated. Blood‐sparing techniques were underused in non‐orthopedic surgery, despite the fact that sufficient time was available to plan appropriate blood‐sparing measures.
