Zusammenfassung der Studie

60 elderly patients undergoing hip fracture surgery were randomized to receive a medical compression stocking applied to the uninjured leg or no compression stocking. Compression stockings were applied after spinal anesthesia and removed 24 hours postoperatively. The primary outcome was the incidence of perioperative hypotension, assessed as intraoperative hypotension (IoH), postoperative hypotension (PoH), and concomitant intraoperative and postoperative hypotension (CoIPH). Secondary outcomes included vasopressor use, blood transfusion requirements, and hypotension-related complications. Outcomes were assessed throughout hospitalization. Overall, the results of the study revealed that compression stocking use significantly reduced the incidence of CoIPH and showed trends toward lower rates of postoperative hypotension and hypotension-related complications. These findings suggest that leg compression may be a simple and effective strategy to reduce perioperative hypotension in elderly patients undergoing hip fracture surgery.
