Brief Summary

Iron deficiency anaemia (IDA) in postoperative patients with confirmed preoperative iron deficiency (ID) in a population with planned major surgery who need fast replenishment of iron as judged by the treating physician will be treated with i.v. iron using Polyglucoferron, Ferric Carboxymaltose or oral iron

Detailed Description

In this study, patients with confirmed and documented preoperative non-anaemic iron deficiency (diagnosis up to 28 days before surgery in routine pre-surgery monitoring) who develop anaemia within 12 to 72 hours after start of surgery (with additional confirmation at Baseline) and for whom fast replenishment of iron stores is necessary, will be included and substituted within 24h after Screening Visit/V1. Peri- or postoperative anaemia will be assessed as soon as possible but earliest 12 h after surgery. For short term safety analysis iron in urine will be measured in the first urine after the end of i.v. administration in the first 35 patients who are eligible for analysis in each i.v. treatment group. Only those patients are eligible for whom haematuria and/or proteinuria are excluded using dip stick test. The Ferric Carboxymaltose treatment arm will be closed if a sufficient number of patients is included for safety analysis.The study will then be continued for assessment of co-primary efficacy endpoint: The effectiveness of postoperative i.v. iron substitution with Polyglucoferron compared to conventional oral iron substitution with Ferrous sulfate (treatment 28 - 35 days) to normalize Hb-values or to increase Hb-values by at least 1.5 g/dl until visit 4 will be evaluated as well as patient related outcomes, such as the decreased need for allogenic blood transfusions. In addition, the well-being of the patient will be assumed to improve after treatment using the SF36 questionnaire.
