Prehospital epinephrine, vasopressin, and steroid for out-of-hospital cardiac arrest

Official title: A Randomized Clinical Trial of Patient Outcomes Following Out-of-Hospital Cardiac Arrest Receiving Epinephrine Versus In-together Vasopressin, Epinephrine, and Steroid. (OHCA REVIVES Trial)

Run by National Taiwan University Hospital · NCT06203847 · Data updated 2026-11-12

This trial tests whether giving epinephrine together with vasopressin and a steroid in the ambulance helps adults with non‑traumatic out‑of‑hospital cardiac arrest in Taipei and New Taipei City achieve sustained return of spontaneous circulation.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older who suffer non‑traumatic out‑of‑hospital cardiac arrest within the Taipei City or New Taipei City EMS systems and are resuscitated by trial‑trained paramedics with vascular access established are the intended participants.

Probably not a fit

Patients with traumatic cardiac arrest, obvious signs of death, DNR orders, known or suspected pregnancy, ROSC before medication, no vascular access, or who received epinephrine before trial paramedics arrive are unlikely to be eligible or receive benefit from the intervention.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized prehospital clinical trial comparing standard epinephrine alone to a combination of epinephrine, vasopressin, and methylprednisolone administered by trained paramedics. The combination arm uses standard epinephrine doses with 20 U vasopressin after each epinephrine dose (up to 80 U) and a single 40 mg dose of methylprednisolone after the first epinephrine. The primary outcome is sustained return of spontaneous circulation (ROSC) and secondary outcomes include longer-term survival. The trial plans to enroll about 1,344 adult non‑traumatic OHCA patients treated by EMS in Taipei City and New Taipei City.

Why it matters

Potential benefit: If successful, the combination treatment could increase rates of sustained ROSC and improve longer-term survival after out‑of‑hospital cardiac arrest.

How similar studies have gone: Previous randomized work combining vasopressin, steroids, and epinephrine showed promising results in some in‑hospital cardiac arrest populations, but evidence for prehospital OHCA is limited and results have been mixed.
