One centre routinely applied low-dose heparinization aiming for a partial thromboplastin time (PTT) of 35\u201340\u00a0s and the other routinely used a high-dose therapeutic heparinization strategy aiming for an activated clotting time (ACT) of 140\u2013180\u00a0s. We assessed number of and time to ECMO oxygenator changes, 15-day freedom from oxygenator change, major bleeding events, thromboembolic events, 30-day ICU mortality, activated clotting time and partial thromboplastin time and administration of blood products. Primary outcome was the occurrence of oxygenator changes depending on heparinization strategy; main secondary outcomes were the occurrence of severe bleeding events and occurrence of thromboembolic events. The transfusion strategy was more liberal in the low-dose centre.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Of 375 screened patients receiving VV-ECMO support, 218 were included in the analysis (117 high-dose group; 101 low-dose group). Disease severity measured by SAPS II score was 46 (IQR 36\u201357) versus 47 (IQR 37\u201355) and ECMO runtime was 8 (IQR 5\u201312) versus 11 (IQR 7\u201317) days (<jats:italic>P<\/jats:italic>\u2009=\u20090.003).
