Aprotinin vs. tranexamic acid in isolated coronary artery bypass surgery: A multicentre observational study

imageBACKGROUND: Aprotinin appears to be more efficacious than lysine analogues to reduce bleeding and transfusion of blood products in high-transfusion-risk cardiac surgical patients. However, in isolated coronary artery bypass graft (CABG) surgery, the results from head-to-head trials remain less conclusive. OBJECTIVE: Our objective was to compare the efficacies and safety of aprotinin and tranexamic acid (TXA) in patients undergoing isolated on-pump CABG. DESIGN: A multicentre before-and-after study pooling individual data from published trials and unpublished data from three other databases. SETTING: Four tertiary care teaching hospitals (Haut-Lévêque Hospital in Bordeaux, Pitié-Salpêtrière Hospital and Bichat-Claude Bernard Hospital in Paris, and Laennec Hospital in Nantes). PATIENTS: We included data of 2496 isolated on-pump CABG surgery patients who received either aprotinin between November 2003 and May 2008 (n = 1267) or TXA between November 2007 and November 2013 (n = 1229). MAIN OUTCOME MEASURES: The primary outcome was total blood loss within 24 h after operation. Secondary outcomes were transfusion of blood products, reoperation for bleeding, renal replacement therapy, ICU length of stay and in-hospital mortality. RESULTS: Adjusted mean (SEM) 24-h blood loss after surgery [483 (11) vs. 634 (11) ml, P
