Interest of S100B Protein for Patient Victim of Minor Traumatic Brain Injury and Treated by Antiplatelet (PETEChIA)

December 19, 2025 updated by: Poitiers University Hospital

All the patients admitted in emergency department for minor traumatized cranial, with antiplatelet therapy, can be included, after checked inclusion and non inclusions criterias. If they are agree, a blood sample for the dosage of S100b will be done.

No other modification of the medical care, all patients will have tomodensitometria, according with recommendations. The aim of the study is to validate the negative predictive value of S100b in this population.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: S100B protein dosing
Biological: S100B protein dosing
Patients under antiplatelet therapy and who have a minor traumatic brain injury will have a blood samples with protein S100B dosage on arrival to the emergency room and after they will have a brain scanner between 4 and 8 hours after the trauma to analyse the negative predictive value with a treshold of 0.105 μg/L
