ABSTRACT
A 28-year-old man known to have mild haemophilia A is admitted following a road traffic accident. He has an expanding intra-abdominal haematoma and requires emergency laparotomy. He has a bleeding disorder registration card that gives his baseline Factor VIII levels as 20 by both the one-stage and chromogenic assays. He is able to tell you that he bleeds infrequently and has previously only received treatment for procedures or trauma-related bleeding. His last treatment was an infusion of desmopressin 3 years before for a dental extraction. Prior to that, he has received Factor VIII concentrate on a few occasions.
