Patients with pertrochanteric hip fracture may benefit from preoperative intravenous iron therapy:: a pilot study

BACKGROUND: Patients undergoing pertrochanteric hip fracture (PHF) repair surgery often receive perioperative allogeneic blood transfusions (ABTs) to avoid the deleterious effects of anemia. Nevertheless, concerns about adverse effects of ABTs have prompted the review of transfusion practice and the search for a safer treatment of perioperative anemia. MATERIAL AND METHODS: The effect of preoperative 200 to 300 mg of intravenous (IV; Group 2; n = 55) iron sucrose administration on transfusion requirements and postoperative morbidity-mortality in patients with PHF has been prospectively investigated. A previous series of 102 PHF patients served as the control group (Group 1). All patients were older than 65 years and were operated on at the third day after admission to the hospital, by the same medical team and with the same implant. RESULTS: Iron sucrose was well tolerated and reduced the transfusion rate in patients with admission hemoglobin levels of greater than 120 g per L (p < 0.05) who also received fewer units of red blood cells (p < 0.05). In addition, iron sucrose reduced postoperative infection rate (p < 0.05), but not 30-day mortality rate or mean length of hospital stay. CONCLUSION: The administration of IV iron sucrose seems to reduce ABT requirements in patients with PHF and is associated to lower postoperative morbidity. The possible mechanisms involved in these effects are discussed.
