Introduction: Percutaneous Stellate ganglion blockade (PSGB) is an increasingly recognised technique for the management of refractory ventricular arrhythmias (VA). Both ultrasound guided and landmark based techniques have been used to successfully decrease the burden of VA. The role of intra-arrest PSGB remains unknown, however it may represent a cost-effective point of care intervention that can be performed for shockable cardiac arrest. Methods: A systematic review of all clinical studies of PSGB performed intra-arrest will be performed across multiple databases. Studies will be included if they described the use of intra-arrest PSGB in humans. Studies will be qualitatively assessed to describe data regarding the PSGB technique, the training of the proceduralist, patient demographics, the context of the arrest and clinical outcomes and complications. This protocol was drafted according to the PRIMSA-P ScR.

This study did not receive any funding

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.

Yes
