Abstract
Background: Pre-operative iron deficiency anaemia (IDA) is common in patients undergoing elective major abdominal surgery and is associated with increased risk of perioperative complications. However, widespread implementation of pre-operative anaemia management is lacking. Guidelines recommend investigation of anaemia preferably 4-6 weeks before surgery to allow time for correction. However, this is not always feasible in abdominal cancer surgery with short time to surgery and may be influenced by concomitant chemotherapy. The objective of this study was to assess the efficacy of implementing a pre-operative screening and treatment programme for IDA in elective abdominal cancer surgery patients, with short duration to surgery and concomitant use of chemotherapy.
Methods: All patients scheduled for elective abdominal cancer surgery with IDA were included. Anaemia was defined according to the World Health Organization-criteria and iron deficiency as a transferrin saturation <0.20. The primary outcome was change in haemoglobin (Hb) between iron infusion and surgery in patients receiving pre-operative intravenous iron infusion.
Results: Of 178 diagnosed IDA patients 134 (75%) received intravenous iron, 103 pre-operatively (58%) at median day 17 (interquartile range: 9-27) before surgery while 31 (17%) received post-operative intravenous iron treatment. The pre-operative Hb increased 0.89 g/dL (95% CI: 0.64-1.13, p < .001) compared to a decrease of 0.4 g/dL (95% CI: 0.19-0.58, p < .001) in 75 patients not treated pre-operatively. Patients diagnosed with severe anaemia had the largest pre-operative Hb increase. Iron infusion >2 weeks pre-operatively resulted in a greater Hb increment of 1.13 g/dL (95% CI: 0.81-1.45) compared to iron infusion ≤2 weeks before surgery 0.48 g/dL (95% CI: 0.16-0.81). Hb increased by 0.64 g/dL (95% CI 0.19-1.21) in patients receiving chemotherapy ≤31 days prior to surgery.
Conclusion: In patients scheduled for abdominal cancer surgery, including in patients with concomitant chemotherapy, pre-operative IDA management is feasible and results in a significant pre-operative Hb increase compared to patients not treated. On the day of surgery 25% patients treated pre-operatively were no longer anaemic.
期刊介绍：
Acta Anaesthesiologica Scandinavica publishes papers on original work in the fields of anaesthesiology, intensive care, pain, emergency medicine, and subjects related to their basic sciences, on condition that they are contributed exclusively to this Journal. Case reports and short communications may be considered for publication if of particular interest; also letters to the Editor, especially if related to already published material. The editorial board is free to discuss the publication of reviews on current topics, the choice of which, however, is the prerogative of the board. Every effort will be made by the Editors and selected experts to expedite a critical review of manuscripts in order to ensure rapid publication of papers of a high scientific standard.
