© 2019 European Society of Anaesthesiology. All rights reserved. BACKGROUNDIt is assumed that transfusion of allogeneic red cells is associated with increased peri-operative mortality and morbidity. Also assumed is the theory of transfusion-related immunomodulation.OBJECTIVEThe aim of this study was to investigate the hypothesis that red cell transfusion specifically leads to an immunological response in surgical patients.DESIGNProspective observational study.SETTINGDepartments of Orthopedic Surgery and Anaesthesia, University Hospital, Thailand.PATIENTSLow-risk, noncancer patients, aged 18 to 75 years undergoing elective major spine surgery, with and without red cell transfusion therapy.INTERVENTIONSBlood specimens were withdrawn four times (prior to surgery and on days 1, 3 and 5).MAIN OUTCOME MEASURESAssessment of immunocompetent cells and cytokines in transfused and nontransfused patients using flow cytometry and multiplex ELISA.RESULTSFrom a total of 78 patients, 61 met the requirements and were analysed in three groups: 19 with no transfusion and 26 and 16 transfused intra-operatively and on day 1 or 2, respectively. No patient experienced peri-operative haemorrhage. Postoperative infection or thrombosis occurred in 5.5% of nontransfused patients and 16.6% of transfused patients; the difference was not significant. There was no significant immunomodulatory effect of red cell transfusion: of 45 immunological parameters, only five little-relevant cytokines were significantly affected, although slightly and nonspecifically.CONCLUSIONOur data indicate that red cell transfusion alone does not create an immunological response in otherwise healthy surgical patients. Our findings do not generally contradict the transfusion-related immunomodulation phenomenon, which has, however, primarily been observed in patients with an already weakened or procedure-deteriorated immune system, such as from malignant disease, significant comorbidity, extensive abdominal/thoracic surgery and cardiopulmonary bypass.TRIAL REGISTRATIONThe study was registered on 15 May 2014, before enrolment of the first patient, at www.ClinicalTrials.gov, NCT02140216.
