Early prognosis value of the first 24 hours mean plasma S100β protein level after subarachnoid aneurysmal hemorrhage

Plasma S100β protein (PS100β) was described as a biological marker of white substance damage and brain ischemia. Studies of new neuroprotective approaches in patients with traumatic brain injury and subarachnoid aneurysmal hemorrhage would benefit from the development of such markers. The aim of this study was to evaluate the first 24 hours mean plasma PS100β for predicting outcome at ICU discharge after subarachnoid aneurysmal hemorrhage (SAH).
