Summary
Aneurysmal subarachnoid hemorrhage (aSAH) can cause a severe headache (HA) that is famously
treatment-resistant. Current pain regimens are too reliant on opioids, which results in
long-term opioid dependence and can obfuscate the neurological examination, which is critical
to detect vasospasm and delayed cerebral ischemia. This study will gather the initial
evidence of whether the pterygopalatine fossa (PPF) regional anesthesia nerve block can treat
aSAH-related HA and reduce opioid consumption in patients with aSAH.
