We aimed to evaluate differences in laboratory tests, bleeding, transfusions, and thrombosis between (1) children without and with cirrhosis and (2) children and adults with cirrhosis, and to correlate thromboelastography (TEG) parameters with biomarkers of hemostasis, bleeding, and transfusions in children and adults with cirrhosis.This single-center, retrospective study included 20 children without cirrhosis, 40 children with cirrhosis, and 40 adults with cirrhosis who underwent a liver transplant (LT). We collected demographic data, preoperative laboratory values, and intraoperative TEG parameters. Biomarkers of hemostasis just prior to the start of LT surgery were analyzed including international normalized ratio (INR), platelet, fibrinogen level, R time, K time, alpha angle (α), and maximum amplitude (MA). We also collected outcome data including blood loss, transfusion requirements, and thrombosis.A significantly higher proportion of children with cirrhosis had abnormal PT ( P = 0.001), platelet ( P = 0.001), K time ( P = 0.02), and MA ( P = 0.05) compared to children without cirrhosis. The incidences of thrombosis, bleeding events, blood loss or PRBC transfusion were not significantly different between these 2 groups. A significantly higher proportion of adults with cirrhosis had abnormal R time ( P = 0.01) and alpha angle ( P = 0.01) than children with cirrhosis.Children with cirrhosis had defects in fibrinogen and platelets compared to children without cirrhosis at time of LT; however, these abnormalities did not translate into higher rates of bleeding in the former. Adults with cirrhosis had more defects in clotting factors compared to children with cirrhosis. |
