Abstract
Objective
To evaluate the efficacy of intravenous iron sucrose (IS) in the
perioperative period of a second thoracotomy after open-heart surgery.
Methods
This study enrolled patients that underwent a second thoracotomy after
previous open-heart surgery. Propensity-score matching was used to match
patients that received oral iron therapy with those that received IS after
admission. The baseline demographic and clinical characteristics,
perioperative data and adverse outcomes were compared between these two
matched groups.
Results
The study enrolled 447 patients: of these, 148 received oral iron therapy and
effective dietary guidance; and 299 patients received 300 mg IS per week.
After matching the propensity scores, there were no significant differences
between the two groups in terms of age, sex, smoking history, incidence of
major cardiac adverse events, Euro-score, time between the two
thoracotomies, application of recombinant erythropoietin, haemoglobin (Hb)
on admission and red blood cell (RBC) count on admission. The differences
between the two groups after propensity-score matching in terms of the
amount of RBC input and Hb after the operation were significant.
Conclusion
The administration of IS might be useful for improving postoperative Hb
levels and reducing intraoperative RBC input in patients undergoing a second
thoracotomy.
