Platelet Administration To Patients With Traumatic Brain Injury Who Were Treated With Aspirin
Summary
Traumatic brain injury (TBI) is a devastating disease with high morbidity and mortality. Although not fully proved, it is commonly accepted that the morbidity and mortality and proportional to the extent of intracranial bleeds (i.e. - larger hemorrhages cause more injury than smaller ones).
Aspirin is a commonly used antiaggregate drug that interferes with the clotting system. The antiaggregate effect may be neutralized by administration of platelets. Thus, potentially, patients receiving Aspirin and undergoing TBI, are at a higher risk for increasing an intracranial bleed.
In this prospective study, the investigators randomize patients receiving aspirin that have a traumatic intracranial bleed to two groups, one - that will receive platelets, and the other that will not receive platelets.
The primary end point of the study is to evaluate the effect of platelet administration of the enlargement of traumatic intracranial bleeds, and try and evaluate any clinical outcome differences between the two groups.

Medical and Biotech [MESH] Definitions
Aspirin
The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)
Sodium Salicylate
A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)
Asthma, Aspirin-induced
Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.
Aspirin, Dipyridamole Drug Combination
A drug combination of aspirin and dipyridamole that functions as a PLATELET AGGREGATION INHIBITOR, used to prevent THROMBOSIS and STROKE in TRANSIENT ISCHEMIC ATTACK patients.
Platelet Adhesiveness
The process whereby PLATELETS adhere to something other than platelets, e.g., COLLAGEN; BASEMENT MEMBRANE; MICROFIBRILS; or other "foreign" surfaces.
