Reduced Platelet Activity in Patients with Acute Intracranial Hemorrhage

Area of Science:

• Neurotrauma
• Hematology
• Critical Care Medicine

Background:

• Acquired platelet dysfunction is a significant factor in trauma-induced coagulopathy, correlating with higher mortality rates.
• Understanding platelet function is crucial in managing patients with acute intracranial bleeding.

Purpose of the Study:

• To determine the prevalence of platelet dysfunction in patients experiencing acute intracranial bleeding.
• To investigate the characteristics of platelet function in this specific patient cohort.

Main Methods:

• Prospective monocentric study involving patients with acute intracranial bleeding requiring craniotomy.
• Platelet function assessed using multiple electrode aggregometry (TRAPtest, ASPItest, ADPtest) and standard coagulation tests.
• Primary outcomes measured by the area under the aggregation curves for ASPItest and ADPtest.

Main Results:

• Out of 49 enrolled patients, 14 (29%) exhibited clinically relevant platelet dysfunction.
• Six patients (12%) were diagnosed with acute acquired platelet dysfunction.
• Eight of the 14 patients with dysfunction were on antiplatelet medication at the time of enrollment.

Conclusions:

• A substantial proportion of patients with acute intracranial bleeding present with decreased platelet function.
• Aggregometric testing should be integrated into hemotherapy protocols for acute intracranial bleeding to guide rapid, targeted treatment.
• Early identification and management of platelet dysfunction are critical for improving outcomes in neurotrauma patients.
