Tranexamic acid

Antifibrinolytic agent that stabilizes clots by preventing their breakdown. Particularly useful in platelet storage pool disorders to compensate for reduced ADP release from dense granules.

medication
3

Medication review and avoidance

Systematic review of all medications to eliminate NSAIDs, aspirin, and other antiplatelet agents that could exacerbate bleeding tendency in patients with abnormal platelet nucleotide ratios.

monitoring

Additional treatment options

Desmopressin (DDAVP)

Synthetic hormone that increases plasma levels of von Willebrand factor and may improve platelet adhesion. Can be administered intravenously or intranasally before procedures.

medication

Platelet transfusion

Transfusion of donor platelets to provide normal platelet function during surgical procedures or for management of significant bleeding episodes.

procedure

Bleeding precautions and injury prevention

Implementation of environmental modifications, protective equipment, and activity restrictions to minimize trauma risk and identify bleeding early.
