Objective To study the influencing factors of perioperative hidden blood loss of femoral intertrochanteric fractures and explore the risk factors for clinical intervention （in-hospital blood transfusion） using retrospective analysis. Methods Data of patients with intertrochanteric fracture admitted to our hospital from 2020 to 2022 were retrospectively analyzed. Their gender, age, height, weight, comorbidities, preoperative and postoperative blood routine test results, postoperative complications, surgical methods, operation time, intraoperative blood loss, and blood transfusion were retrieved, and grouped accordingly. A t-test was used to analyze the amount of blood loss between different groups, and a binary logistic regression was used to evaluate the risk factors for in-hospital blood transfusion secondary to perioperative hidden blood loss in patients. Results A total of 274 patients were retrospectively analyzed, including 125 males and 149 females, 151 cases with left fracture and 123 cases with right fractue. All of the patients were treated by surgery without serious complications. The average operation time was （65.16±23.61） min, the total blood transfusion volume was （386±293） mL, the total blood loss volume was （862±477） mL, of which the average hidden blood loss volume was （753±444） mL, and the average hospitalization was （12.77±4.69） d. Unstable fracture （Evans Ⅲ-Ⅳ） was an influencing factor for increased hidden blood loss （P<0.05）. Age, body mass index, and comorbidities had no significant effect on total blood loss or hidden blood loss volume. Long operative time and low preoperative hemoglobin level were main risk factors for blood transfusion secondary to perioperative hidden blood loss （P<0.05）. Conclusion Unstable fracture is an influencing factor for hidden blood loss during perioperative femoral intertrochanteric fractures, and long operation time and low preoperative hemoglobin level are risk factors for in-hospital blood transfusion secondary to perioperative hidden blood loss.
