Stroke; a journal of cerebral circulation

Systemic inflammatory response syndrome (SIRS) without infection is a well-known phenomenon that accompanies various acute cerebral insults. We sought to determine whether the initial SIRS score was associated with outcome in subarachnoid hemorrhage (SAH). ⋯ In SAH patients, SIRS on admission reflected the extent of tissue damage at onset and predicted further tissue disruption, producing clinical worsening and, ultimately, a poor outcome.
