Sponsor's own description

BLOCK-SAH is a phase II, multicenter, randomized, double-blinded, placebo-controlled clinical trial with a sequential parallel comparison design (SPCD) of bilateral pterygopalatine fossa (PPF) injections with 20mg ropivacaine + 4mg dexamethasone (active, PPF-block) compared to saline (placebo) for headache in survivors of aneurysmal subarachnoid hemorrhage (SAH), while monitoring intracranial arterial mean flow velocities with transcranial Doppler (TCD) peri-intervention (intervention = PPF-injections: active or placebo)
