Two Cases of Postoperative Bleeding Monitored by Thromboelastography in Reoperation of Open Heart Surgery / 대한마취과학회지

The excessive postoperative hemorrhage increases the mortality and morbidity after surgery. The longer expracorporeal circulation time, the worse the patient's blood coagulation disorder. And it makes the possibility of bleeding tendency predictable. We have two clinical experiences of reoperation due to postoperative hemorrhage after open-heart surgery. As with the heparin independent thromboelastography(TEG) following Cardiopulmonary Bypass(CPB) and postbypass TEG, we could distinguish expectantly surgical bleeding from medical bleeding relating with open heart surgery.
