Impact of Preoperative Treatment of Anemia and Iron Deficiency in Cardiac Surgery on Outcome.

This study is currently recruiting participants.

Verified May 2017 by University of Zurich

Information provided by (Responsible Party):
University of Zurich
ClinicalTrials.gov Identifier:
NCT02031289
First received: December 16, 2013
Last updated: May 4, 2017
Last verified: May 2017
  Purpose

We are performing the above prospective randomized trial in 1'000 patients undergoing cardiac surgery. The study will answer the question of whether preoperative treatment of anemia or iron deficiency indeed improves transfusion needs (primary outcome) and important clinical outcomes (secondary outcome) in a large group of cardiac surgical patients. The list of inclusion and exclusion criteria was deliberately chosen short so that this patient group largely reflects today's clinical practice .

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Care Provider, Investigator, Outcomes Assessor
Primary Purpose: Treatment
Official Title: Impact of Preoperative Treatment of Anemia and Iron Deficiency in Cardiac Surgery on Outcome.

Primary Outcome Measures:
  • Red blood cell (RBC) units transfused [ Time Frame: 7 days ]

Secondary Outcome Measures:
  • Percentage of patients without any RBC transfusions [ Time Frame: 90 days ]
  • Combined allogeneic transfusions (RBC, FFP( fresh frozen plasma), platelets) [ Time Frame: 90 days ]
  • Length of stay in the intensive care unit (ICU) [ Time Frame: 90 days ]
  • Duration of mechanical ventilation [ Time Frame: 90 days ]
  • Acute kidney failure [ Time Frame: 7 days ]
    RIFLE I, AKIN 2

  • Major Adverse Cardiac and Cerebrovascular Events (MACCE) [ Time Frame: 90 days ]
    Myocardial infarction, stroke, death

  • New atrial fibrillation [ Time Frame: 90 days ]
  • Infections [ Time Frame: 7 days ]

    Pneumonia, hospital acquired Deep Sternal Wound Infection

    Definition of infection: rise in inflammation markers after the initial postoperative period (acute phase reaction) and requires treatment and/ or prolongs days in hospital and/or microbiological confirmation of infection


  • Thrombotic and thromboembolic complications (90 days) [ Time Frame: 90 days ]
    clinical symptoms and evidence of thrombosis/ embolism in one of the following imaging methods (ultrasound, CT-scan)

  • Length of stay (LOS) in the hospital [ Time Frame: 90 days ]
  • Length of hospital stay (in comparison to median LOS published for relevant Swiss-DRGs) [ Time Frame: 90 days ]
  • In hospital mortality [ Time Frame: 90 days ]
  • 30 day and 90-day mortality [ Time Frame: 90 days ]
  • Costs (for blood products and pharmaceutical products related to transfusion and anemia management) [ Time Frame: 90 days ]
    Comparison of costs for study medication versus costs for blood products and products related to transfusion

  • Perioperative Hb concentrations [ Time Frame: 90 days ]
  • Calculated RBC and blood loss [ Time Frame: 90 days ]
  • Comparison of the treatment and placebo groups with the natural comparison group [ Time Frame: 90 days ]
  • Safety and tolerance of administered study drug and placebo [ Time Frame: 90 days ]
    Comparison of all serious adverse events between study drug group and placebo group

Patients without anemia or iron deficiency will be observed and the same postoperative measurements performed

Detailed Description:

Anemic or iron deficiency patients are randomized into treatment and placebo groups. Treatment (see below) will be given the day before the operation (day -1) or a maximum of 2 days prior to the operation (day -2) in iron deficiency patients and a maximum of 3 days prior to the operation in anemic patients (day -3). The treatment will not be disclosed to the patient or the health care workers treating the patients during and after the operation.

Patients without anemia or iron deficiency will also be observed and the same postoperative measurements performed. They will serve as a natural comparison group.

Treatment:

Erythropoietin alpha (Eprex, Janssen-Cilag AG, Baar) 40'000 U sc. Ferric carboxymaltose (Ferinject, Vifor (International) AG, St. Gallen) 1000 mg in 100 ml sodiumchloride (NaCl) over 30 min.

Vitamin B12 (Vitarubin®-superconc., Streuli Pharma AG, Uznach) 1 mg sc. Folic acid (Acidum folicum, Streuli Pharma AG, Uznach) 5 mg po.

The current transfusion and coagulation guidelines of the University Hospital of Zurich are followed in both groups identically. Postoperatively on the regular ward a Hb transfusion trigger of 80 g/L is applied
