Blood coagulation of 65 patients that needed reoperation to control excessive bleeding after cardiopulmonary bypass surgery was evaluated by hematologist that didn't know the reoperation findings. Forty-six (90.2%) of 51 patients with normal tests before the reintervention had localizated bleeding, and five (9.8%) had difuse hemorrhage. From 14 patients with abnormal coagulation tests, eight (57.2%) had difuse bleeding and six (42.8%) had a localizated bleeding. The authors concluded that with normal coagulation tests and excessive bleeding after cardiopulmonary bypass surgery a new reoperation is indicated. Otherwise, patients with abnormal coagulation tests can receive initial clinical treatment.
