Anticoagulation Management in Complex Cardiac Surgery

Overview

The goal of this clinical trial is to compare the anticoagulation management with or without heparin concentration level guidance, in patients undergoing valve or complex cardiac surgery during cardiopulmonary bypass using closed, coated circuits. The main questions it aims to answer are: * initial heparin bolus, subsequent supplementary doses and total heparin variance among groups. * protamine dose among groups. Participants are adult patients scheduled for valve or complex cardiac surgery. They are randomised to either Activated Clotting Time guided management alone or combined with heparin level concentration monitoring.
