FEMART-1 Pilot Study (FEMART-1)

2026년 5월 18일 업데이트: Emergency Medical Service, Prague

The FEMART-1 Pilot Study is focused on evaluating the feasibility, safety, and procedural timing of prehospital femoral arterial sheath placement in patients with non-traumatic out-of-hospital cardiac arrest (OHCA), both during ongoing cardiopulmonary resuscitation and after return of spontaneous circulation (ROSC).

The primary objective of the study is to enable invasive arterial blood pressure monitoring for targeted and continuous hemodynamic management using vasopressor therapy in the prehospital setting. The study evaluates the feasibility, safety, and procedural performance of invasive arterial monitoring with the aim of improving assessment of the patient's hemodynamic status and enabling more accurate titration of vasopressor support. This approach may reduce episodes of hypotension and decrease the risk of recurrent cardiac arrest while allowing safer transport to specialized cardiac arrest centers.

Femoral arterial access enables more precise monitoring of perfusion pressure, targeted vasopressor titration, and early recognition of impending circulatory collapse. The intervention may contribute to improved early organ perfusion and could be associated with more favorable neurological and overall clinical outcomes after cardiac arrest. In accordance with the ERC Guidelines 2025, which emphasize active hemodynamic optimization after ROSC and acknowledge the potential role of invasive arterial pressure monitoring during ongoing resuscitation, the study evaluates not only feasibility, safety, and procedural timing, but also the potential clinical benefit of continuous hemodynamic-guided management in the prehospital phase, including (1) early identification of hypotension, (2) targeted vasopressor administration, and (3) prevention of re-arrest.

The study is conducted by the Prague Air Rescue Service Kryštof 01 (Prague Emergency Medical Services) in collaboration with the Central Bohemian Emergency Medical Service, the Second Department of Internal Medicine - Cardiology and Angiology of the General University Hospital in Prague and First Faculty of Medicine, Charles University, and the Department of Anesthesiology, Resuscitation and Intensive Care Medicine of the General University Hospital in Prague and First Faculty of Medicine, Charles University.

FEMART-1 is designed as a prospective pilot study without external funding.

활성 비교기: Prehospital Femoral Arterial Sheath Insertion
Patients receive standard advanced prehospital resuscitation and post-resuscitation care including ultrasound-guided femoral arterial sheath insertion for invasive blood pressure monitoring and potential facilitation of subsequent VA-ECMO cannulation if clinically indicated.
절차: Prehospital Ultrasound-Guided Femoral Arterial Sheath Placement
Ultrasound-guided placement of a femoral arterial sheath in the prehospital setting during ongoing cardiopulmonary resuscitation or after return of spontaneous circulation. The procedure is performed to enable invasive arterial blood pressure monitoring, optimization of hemodynamic management during ongoing cardiopulmonary resuscitation or post-resuscitation care, prevention of re-arrest, and to facilitate rapid transition to potential VA-ECMO cannulation if clinically indicated.
