In our study, we aimed to investigate the sufficiency of 2 and 5 min. waiting time that is required for activated clotting time measurement after anticoagulation with heparine for cardiopulmonary by-pass in the patients undergoing coronary artery surgery. 50 patients undergoing elective cardiopulmonary bypass (CPB) were included to the study. Standard premedication, monitorization, anesthesia induction and maintenance were applied to all patients. 300 U kg-1 heparin was applied before left internal mammarian artery clamping during the surgical procedure. After heparin application ACT values that were measured in 2 and 5th min. were compared. In conclusion, we found that in order to control ACT value, there is no statistical difference between taking blood 2 min. after and taking blood 5 min. after heparin application. Especially in cases that required urgent aortic cannulation and induction of cardiopulmonary by-pass, 2 minutes waiting time for ACT is safe as well as 5 minutes waiting time.
