We want to analyse patients from a diagnostic point of view (occult blood, diverticulitis, gastrorrhagia) and from the point of view of laboratory parameters (blood count, serum iron, transferrinemia, ferritinemia, transferrin saturation) in ordr to be able to suggest the best approach in preparation to the intervention.~We want to evaluate the effectiveness of this approach, considering the proposed treatments (ferric carboxymaltose, chelated iron, folic acid, sideremil vita) and the transfusion result (or not) obtained
We have been well guided in the Good use of blood during major surgery for many years, reaching a percentage of 4% of patients transfused after elective prosthetic operations. Valid patient blood management must provide for the possibility of limiting/zeroing the transfusion risk dependent on preoperative anemia, and the national guideline on PBM (Patient blood management) also underlines this Hypothesis and relevance
