NCT04620070

Brief Summary

Hypothesis: Implantation of on-scene ECPR by the HEMS teams in patients with sustained out-of-hospital cardiac arrest, results in the rapid return of circulation and, thus, improved survival and less neurological impairment, which is associated with lower health care costs.

Outcome Measures

Primary Outcomes (1)

  • Hospital Survival

    (% patients surviving hospital discharge)

    Hospital discharge (on average 6 weeks)

Secondary Outcomes (2)

  • Favourable neurological outcome (CPC 1-2)

    6 months after cardiac arrest

  • Survival prehospital ECPR vs ECPR at the hospital vs no ECPR

    Hospital discharge (on average 6 weeks after cardiac arrest)

Study Arms (2)

Conventional

NO INTERVENTION

In the Netherlands, out-of-hospital cardiac arrest (OHCA) is managed by paramedics. In this study, in the conventional arm, OHCA is managed by a physician of the Helicopter Emergency Medical Services (HEMS), but without the possibility of prehospital ECPR.

Intervention group

EXPERIMENTAL

OHCA managed by the physician of the HEMS team, but with the possibility of prehospital ECPR.

Procedure: ECPR

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Witnessed arrest (last seen well \<5 min), OR signs of life (gasping, movement)
  • Initial rhyme is VT/VF OR Suspected of having a pulmonary embolism
  • Refractory cardiac arrest lasting longer than 20 minutes and shorter than 45 min

You may not qualify if:

  • \- CO2 et\<1.2 kPa (10 mmHg) during CPR
  • No clear echographic visualisation of either the femoral artery or the femoral vein.
  • Expected time from collapse to arrival at an ECPR center with a direct available ECPR team is less than 30 min.
  • Known malignancy
  • Known intracranial haemorrhage/ischemia \<6 weeks
  • Care dependent for daily activities before arrest
  • Patients with a "do not resuscitate" order, which was not known at time of the arrest.
  • Refusal of deferred consent by the next of kin or by the patient himself to use the data. Deferred consent will not be asked to relatives of patients who die in scene, but are included in the study.
