Transnasal Sphenopalatine Ganglion Block for Treatment of Acute Subarachnoid Hemorrhage Associated Headache
University of California, Davis
Summary
The study titled \"Transnasal sphenopalatine ganglion block for treatment of acute subarachnoid hemorrhage associated headache\" is a randomized controlled pilot study aimed at evaluating the efficacy of a transnasal sphenopalatine ganglion (SPG) block in addition to standard pain medication for reducing headache severity in patients with acute subarachnoid hemorrhage (aSAH). The study also examines whether this intervention can reduce opioid requirements during hospitalization and upon discharge.
Description
The study is designed to test the hypothesis that the addition of a transnasal SPG block to standard pain medication is more effective than medication alone in reducing headache associated with acute subarachnoid hemorrhage. It involves 40 participants who meet specific inclusion criteria, such as being over 18 years old, having a secured aneurysm, and the ability to verbalize pain scores. Those with conditions like recent nasal or facial trauma, allergies to specific anesthetics, or pregnancy are excluded. Participants are randomized into two groups: one receiving the standard care medicatio…
