Testing a device to stimulate the vagus nerve after a brain hemorrhage

Investigating the Tolerability and Feasibility of Transcutaneous Vagus Nerve Stimulation Following Aneurysmal Subarachnoid Haemorrhage

Not applicable Interventional Sheffield Teaching Hospitals NHS Foundation Trust · NCT06374693

This study is testing whether a device that stimulates the vagus nerve can help people recover better after a brain hemorrhage caused by a burst aneurysm.

What this trial studies

This pilot study investigates the tolerability and feasibility of transcutaneous vagus nerve stimulation (tVNS) in patients who have recently experienced a subarachnoid hemorrhage from a cerebral aneurysm rupture. Participants will be randomly assigned to receive either active tVNS or a sham treatment for 45 minutes twice daily over five days following their aneurysm securing procedure. The study aims to evaluate the success criteria for tolerability and feasibility while also exploring potential effects on clinical outcomes and mechanisms. This research is significant as it seeks to address complications associated with subarachnoid hemorrhage, which can lead to increased disability and mortality.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 who have been admitted to the neurosurgery department with a confirmed aneurysmal subarachnoid hemorrhage and have undergone aneurysm securing within the last five days.

Not a fit: Patients with prior vagus nerve stimulation treatment or certain cardiac conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could reduce complications and improve recovery outcomes for patients following a subarachnoid hemorrhage.

How similar studies have performed: While non-invasive vagus nerve stimulation has been explored for headache relief, this specific application in the acute phase following subarachnoid hemorrhage is novel and has not been extensively tested.
