On bleeding and clotting problems in post-traumatic states.

The most common bleeding and clotting problems in post-traumatic states are reviewed. The normal response of the coagulation system and the fibrinolytic system to trauma is described; this response must be considered when studying the abnormal situations. The laboratory tests need not be numerous or sophisticated but they must be repeated often enough to understand and interpret the data. A proper understanding of these abnormalities forms the rational basis for the correct choice of therapy, and is of utmost importance in the management of post-traumatic patients.
