Efficacy of Scalp Block in Managing Post Subarachnoid Hemorrhage Headache in Critically Ill Patients. A Single Centre Randomized Controlled Trial

Subarachnoid hemorrhage (SAH) is a devastating neurological disorder associated with significant mortality and morbidity rates, arising not just from the hemorrhage itself but also because of the catastrophic multisystem sequelae that can accompany the condition. Rupture of an intracranial aneurysm accounts for up to 85% of instances of SAH, occurring in approximately 3 to 25 people per 100,000 annually in most populations. Treatment of aneurysmal SAH (aSAH) includes prevention of re-bleeding, evacuation of space-occupying hematomas, management of hydrocephalus, and prevention of secondary cerebral insult. Severe headache is the predominant characteristic symptom of aSAH, developing almost instantaneously at ictus in 50% of cases and continuing into the first days. Its severity has a variety of physiological and psychological effects on the patient. Scalp blocks have been suggested to alleviate this headache in case series. However, there is no strong evidence supporting this intervention. In this study, we aim to assess the impact of scalp blocks on headache reduction in patients undergoing endovascular treatment of an aneurysm (coiling or flow diversion) with aneurysmal subarachnoid bleeding.
