[A retrospective study on perioperative bleeding in patients for hip fracture surgery in patients treated with or without antiplatelet/anticoagulating drugs].

Background: Early operation for hip fracture patients is considered to have better outcome. Therefore, early operation was performed even if patients had been treated with antiplatelet and/or anticoagulating drugs (AP/AC) in our hospital for the past two years. This retrospective study was undertaken as excessive blood loss is expected in patients treated with AP/AC.

Methods: Elderly patients for hip fracture surgery were retrospectively studied in our hospital for the past two years. Perioperative decrease in hemoglobin level and the incidence of transfusion were compared between patients treated with AP/AC and those not treated.

Results: Sixty-four patients were treated with AP/AC and one hundred ninety-nine patients were not treated. Patients treated with AP/AC had more preoperative complications and worse ASA-PS scores. General anesthesia was used more frequently for patients with AP/AC. In the perioperative decrease in hemoglobin level and the incidence of transfusion, there were no significant differences between the groups.

Conclusions: Perioperative bleeding for hip fracture surgery was compared between patients treated with and without AP/AC. No significant difference was observed, and, discontinuation of AP/AC might not be necessary for hip fracture surgery.
