Preoperative intravenous iron to treat anaemia before major abdominal surgery (PREVENTT): a randomised, double-blind, controlled trial. Lancet. 2020;6736(20):1–9. A multicenter randomized trial, which compares preoperative intravenous iron to placebo in anemic patients undergoing major abdominal surgery. The results demonstrated that administering a single dose of intravenous iron relatively close surgery to did not yield any short-term benefit but may reduce postoperative hospital re-admission rates.
