Abstract
Desmopressin (1-deamino-8-D-arginine vasopressin, DDAVP) is a synthetic analogue of the antidiuretic hormone L-arginine vasopressin. Because it can raise circulating levels of Factor VIII and of von Willebrand's factor, DDAVP is used for nontransfusional treatment of mild and moderate hemophilia and von Willebrand's disease. DDAVP also shortens the prolonged skin bleeding time in patients with uremia, liver cirrhosis, and platelet dysfunctions and is given to prevent or stop excessive bleeding in such conditions. Finally, there is evidence that DDAVP can reduce blood loss and transfusion requirements during and after surgical operations in which blood losses are unusually large. Hence DDAVP is useful as a nontransfusional hemostatic agent in many of the bleeding disorders frequently encountered in clinical practice.
