Heparin levels and activated clotting time (ACT) during open heart surgery.
Heparin levels were followed by an amidolytic method during open heart surgery in 10 adult patients and correlated to the activated clotting time (ACT) (Haemochron). There was a good correlation between the 2 parameters when the ACT was below 600 s. Based on the present and previous studies of the ACT the authors conclude that the ACT is a useful tool in control of heparinization during open heart surgery.
