Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Aneurysmal subarachnoid hemorrhage is a life-threatening condition that occurs when a cerebral aneurysm ruptures, causing bleeding into the subarachnoid space. Surgical clipping of the aneurysm is a standard procedure used to stop the bleeding and prevent re-rupture, thereby stabilizing the patient's condition.
Remote ischemic conditioning (RIC) is a non-invasive treatment that involves using a blood pressure cuff to induce brief, temporary cycles of ischemia and reperfusion in a limb. Research suggests that this process may confer systemic protective effects, potentially improving recovery from brain injury or surgery. Although RIC has shown potential to improve outcomes in patients with other neurological conditions, its effect on patients with aSAH who undergo surgical clipping remains unclear.
This study will evaluate whether RIC can reduce complications, improve neurological function, and enhance overall recovery in these patients. The findings will help determine whether RIC should be incorporated into the standard treatment regimen for aSAH.
