Treatment of the Bleeding Patient
How does DDAVP function for platlets
to release von Willebrand factor and factor 8 from endothelial cells.
In addition, it enhances the density of platelet surface glycoprotein receptors, thereby increasing their adhesion potential.
A dose of 1 mcg/kg subcutaneously should be considered in patients with evidence of platelet dysfunction. DDAVP administration could be repeated every 24 hours for up to 3 days, although there is about a 30% reduction in its efficacy compared with the initial administration.
