BACKGROUND

Management of traumatic brain injury (TBI) is focused on preventing secondary brain injury. Remote ischemic conditioning (RIC) is an established treatment modality that has been shown to improve patient outcomes secondary to inflammatory insults. The aim of our study was to assess whether RIC in trauma patients with severe TBI could reduce secondary brain injury.

METHODS

This prospective consented interventional trial included all TBI patients admitted to our Level 1 trauma center with an intracranial hemorrhage and a Glasgow Coma Scale (GCS) score of 8 or lower on admission. In each patient, four cycles of RIC were performed within 1 hour of admission. Each cycle consisted of 5 minutes of controlled upper limb (arm) ischemia followed by 5 minutes of reperfusion using a blood pressure cuff. Serum biomarkers of acute brain injury, S-100B, and neuron-specific enolase (NSE) were …
