Summary
This study tests whether a cervical sympathetic block (an injection near the spine) can increase blood flow to the brain in patients who develop narrowed blood vessels (vasospasm) after a bleeding aneurysm. Ten adults in the ICU will receive the block, and researchers will measure changes in brain blood flow and neurological function. The goal is to see if this simple procedure can help recovery.
