Summary

This study tests whether a scalp block (a numbing injection) can reduce severe headaches in patients who have had a brain aneurysm rupture. About 22 adults in intensive care will receive either standard care plus the scalp block or standard care alone. The goal is to see if the block lowers pain and the need for strong painkillers like opioids.
