{Abstract}: BACKGROUND: Patient blood management recommends the use of intravenous (IV) iron infusion to reduce inappropriate blood transfusion perioperatively for anaemic surgical patients. However, evidence regarding its use in urgent femoral fracture surgery is limited. This systematic review aims to collate the current evidence regarding the utilisation of IV iron in femoral fracture surgery.
METHODS: MEDLINE, Embase, Cochrane CENTRAL, Clinicaltrials.gov, and the WHO ICTRP databases were systematically searched for randomised controlled trials (RCT) comparing the outcomes of perioperative IV iron infusion with placebo in adults requiring surgical management for femoral fractures. Risk ratios (RR) were calculated using the Mantel-Haenszel method for dichotomous outcomes, and mean differences (MD) were calculated with the inverse-variance method for continuous outcomes.
RESULTS: Six RCTs with 1292 patients were included. No statistically significant difference was found in the proportion of patients receiving red blood cell (RBC) transfusion (RR = 0.87, 95%CI: 0.75; 1.01, p = 0.058) between groups. Statistically significant difference in postoperative haemoglobin concentration was found between groups measured between day 4-7 of admission (MD = 1.93 g/L, 95%CI: 0.48; 3.39, p = 0.024), but not clinically significant. No statistically significant differences were found between groups in mortality rate, length of hospital stay, infection rate, or return to home rate.
CONCLUSIONS: Current evidence indicates that IV iron infusion alone does not provide any clinically significant benefit in femoral fracture surgery. Further high-quality RCTs are needed to explore its synergistic potential when used in combination with other perioperative optimisation methods, including tranexamic acid, erythropoietin and cell salvage.
