Using a nerve block to improve outcomes in cardiac arrest patients

Percutaneous Left Stellate Ganglion Block In Out-of-hospital Cardiac Arrest Due to Refractory VEntricular Arrhythmias

Observational Fondazione IRCCS Policlinico San Matteo di Pavia · NCT04168970

This study is testing if a special nerve block can help people who have had a cardiac arrest due to a severe heart rhythm problem by seeing if it increases their chances of getting their heart beating again.

What this trial studies

This observational study aims to evaluate the feasibility and effectiveness of performing a percutaneous stellate ganglion block (PSGB) in patients experiencing out-of-hospital cardiac arrest (OHCA) due to refractory ventricular fibrillation. The study will enroll patients who meet specific criteria and will assess whether PSGB can increase the rate of return of spontaneous circulation (ROSC) compared to historical controls. The intervention will be conducted by emergency medical personnel after standard advanced cardiac life support (ACLS) measures have been attempted. The study will also monitor for any complications related to the procedure.

Who should consider this trial

Good fit: Ideal candidates are patients who have suffered an out-of-hospital cardiac arrest with a shockable rhythm.

Not a fit: Patients whose cardiac arrest is due to non-medical causes or who have contraindications for the procedure will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve survival rates and outcomes for patients experiencing cardiac arrest.

How similar studies have performed: While this approach is novel in the context of OHCA, similar interventions have shown promise in other settings, but specific outcomes for this method remain untested.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* All patients with an OHCA occurred in the Province of Pavia in which the first rhythm was a shockable one

Exclusion Criteria:

* Patients in which the cause of the cardiac arrest is non-medical following Utstein-style 2014 (trauma, overdose, drowning, electrocution, asphyxia)
* Patients who has an anisocoria at the arrival of medical doctor on the scene
* Patients whose neck is judge unsuitable for PSGB by the operator (i.e. presence of big scar, thyroid goiter, etc.)
