Superimposed traumatic brain injury modulates vasomotor responses in third-order vessels after hemorrhagic shock

摘要

BackgroundTraumatic brain injury (TBI) and hemorrhagic shock (HS) are the leading causes of death in trauma. Recent studies suggest that TBI may influence physiological responses to acute blood loss. This study was designed to assess to what extent superimposed TBI may modulate physiologic vasomotor responses in third-order blood vessels in the context of HS.
