Study Objective: To identify risk factors for coagulopathy in patients undergoing liver resection. Design: A retrospective cohort study. Setting: Patients who underwent liver resection at a university hospital between April 2010 and May 2011 were evaluated within seven days after surgery. Patients: One hundred forty-seven patients were assessed for eligibility. Thirty needed to be excluded because of incomplete data (23) or a preexisting coagulopathy (7). Measurements: Coagulopathy was defined as 1 or more of the following events: international normalized ratio >= 1.4, platelet count <80,000/mu L, and partial thromboplastin time >38 seconds. Related to the time course and coagulation profile thresholds, 3 different groups could be distinguished: no coagulopathy, temporary coagulopathy, and persistent coagulopathy. Main Results: Seventy-seven patients (65.8%) had no coagulopathy, whereas 33 (28.2%) developed temporary coagulopathy and 7(6%) developed persistent coagulopathy until day 7. Preoperative international normalized ratio (P = .001), postoperative peak lactate levels (P = .012), and resected liver weight (P = .005) were identified as independent predictors. Preoperative liver transaminases and transfusion volumes of red blood cells and fresh frozen plasma were significantly higher in patients with persistent coagulopathy. Conclusions: Epidural anesthesia is feasible in patients scheduled for liver resection. Caution should be observed for patients with extended resection 3 segments) and increased postoperative lactate. In patients with preexisting liver disease, epidural catheters should be avoided.
