The Effectiveness of Preoperative Iron Therapy in Improving Anemia After Multi-level Lumbar Fusion in the Elderly

Ferric Carboxymaltose

Preoperative iron therapy has important value in improving the outcomes after lumbar fusion surgery, but there is significant heterogeneity in both domestic and international studies. International studies provide high-level evidence-based evidence for intravenous iron, but lack spinal surgery-specific data; domestic studies focus on the comparison of iron types and the improvement of clinical practice, but high-quality evidence is still insufficient. At present, there are still few studies on preoperative iron therapy in the field of spinal surgery, especially its specific impact on the prognosis of patients after lumbar fusion surgery is still unclear. Therefore, it is particularly important to study the preoperative iron supplementation regimen for lumbar fusion surgery to improve the efficacy and safety. Through multidisciplinary collaboration and technological innovation, preoperative iron therapy is expected to become an important part of accelerated recovery after lumbar fusion surgery.

This study aimed to investigate the correlation between ferric carboxymaltose and iron deficiency anemia (IDA) patients with or without concurrent iron therapy on hemoglobin changes, 90-day adverse events, and satisfactory health-related quality of life (HRQOL) indicators after multilevel lumbar spine fusion. Outcome measures 1. Differences in hemoglobin and iron metabolism indicators (serum iron, ferritin, transferrin, transferrin saturation) levels on the 1st, 4th, 7th day after surgery and at discharge 2. Differences in the incidence of adverse events and length of hospital stay within 90 days after lumbar multilevel fusion surgery Any adverse event (AAE): serious or minor adverse event Serious adverse events (SAE): pulmonary embolism, wound infection, deep vein thrombosis, sepsis, myocardial infarction, neurological complications, delirium, septic shock, reoperation Minor adverse events (MAE): wound dehiscence, hematoma, other wound complications, acute kidney injury, blood transfusion, cerebrospinal fluid leak, urinary tract infection, pneumonia 3. Study-specific surveys conducted at the time of assessment included the following health status-related quality of life scores (HRQOL): Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and EuroQol-5D (EQ-5D), 36-Item Short Form Health Survey (SF-36)
