Trauma is a serious global health problem, accounting for approximately one in 10 deaths worldwide. Uncontrollable bleeding accounts for 39% of trauma-related deaths and is the leading cause of potentially preventable death in patients with major trauma. While bleeding from vascular injury can usually be repaired surgically, coagulopathy-related bleeding is often more difficult to manage and may also mask the site of vascular injury. The causes of coagulopathy in patients with severe trauma are multifactorial, including consumption and dilution of platelets and coagulation factors, as well as dysfunction of platelets and the coagulation system. The interplay between hypothermia, acidosis and progressive coagulopathy, referred to as the 'lethal triad', often results in exsanguination. Current management of coagulopathy-related bleeding is based on blood component replacement therapy. However, there is a limit on the level of haemostasis that can be restored by replacement therapy. In addition, there is evidence that transfusion of red blood cells immediately after injury increases the incidence of post-injury infection and multiple organ failure. Strategies to prevent significant coagulopathy and to control critical bleeding effectively in the presence of coagulopathy may decrease the requirement for blood transfusion, thereby improving clinical outcome of patients with major trauma.

BACKGROUND: During surgical procedures, patients with bleeding disorders have a major risk of bleeding complications. To reduce the risk of bleeding it is necessary to provide pre-, peri- and postoperative antihaemorrhagic therapy. In less severe bleeding disorders, pharmacologic treatment may be sufficient, but in patients with severe bleeding disorders there is always a need for clotting factor concentrates. MATERIALS AND METHODS: This study includes all patients with bleeding disorders admitted to Rikshospitalet University Hospital between 1997 and 2003 for surgical procedures during which therapy with clotting factor concentrates was mandatory. RESULTS AND INTERPRETATION: Over the study period, 135 patients underwent a total of 255 different surgical procedures. In 47% of the patients there was a causal relationship between the need for surgery and the bleeding disorder. Our results show that patients with severe bleeding disorders, including patients with inhibitors, can be treated safely provided that the patients receive adequate treatment with clotting factor concentrates. However, substitution therapy with clotting factor concentrates is very expensive. Cost related to substitution therapy is the main determinant of how many patients with severe bleeding disorders can undergo elective surgery in our hospital each year.
