Hemostasis in children undergoing liver transplantation.

We reviewed the records of 200 children who underwent 238 orthotopic liver transplantations in order to determine which preoperative factors could predict intraoperative blood loss. A coagulation abnormality score (CAS) was calculated by allowing one point for each abnormality in six preoperative coagulation tests. The mean CAS values were significantly greater in children suffering from fulminant hepatic failure (Fulm) or post-necrotic cirrhosis (PNC) and those having retransplantation (ReTx) than in those with disease of other etiologies.

Analysis of coagulation and fibrinolysis after intravenous anisoylated plasminogen streptokinase activator complex or heparin in patients with acute myocardial infarction. A Belgian multicentre study.

A multicentre randomised trial including 87 patients admitted for acute myocardial infarction compared the effects of a single intravenous bolus of an anisoylated plasminogen streptokinase activator complex (APSAC) 30 units with those of heparin treatment on haemostasis during the first 4 days after treatment. In the APSAC group, a rapid and significant reduction in fibrinogen, plasminogen and alpha 2-antiplasmin was observed, associated with an increase of fibrin(ogen) degradation products, reflecting a strong systemic lytic activity. None of these parameters were significantly modified by heparin, but the anticoagulant effect was apparent as assessed by the activated partial thromboplastin time.
