Comparison of impairment of blood coagulation during peri-op between two groups. x-axis type of impairment of blood coagulation, A heparin residual, B coagulopathy for low PLT, C coagulopathy for low FIB, D coagulopathy for low clotting factors, E hyperfibrinolysis, T total (A + B + C + D + E). y-axis cases of each type, T 1 at the time of after anesthesia induction and 5 min before surgery, T 2 5 min after heparin was reversed by protamine during surgery, T 3 at the end of surgery, post-op during postoperative period, T 4 at the time of 24 h after surgery. *p = 0.024(T3 − A), 0.043(T3 − T), 0.010 (post-op − A), 0.040 (post-op − T), respectively
