The summary below is from an episode of ERcast: Clinical Perspectives
Vasopressin plus methylprednisolone during in-hospital cardiac arrest increases return of spontaneous circulation, but whether that translates into meaningful patient benefit remains uncertain. The VAM-IHCA trial puts a hard spotlight on ROSC as a surrogate outcome in adult IHCA resuscitation.
VAM-IHCA Trial Takeaways
- ROSC signal strength: The intervention improved sustained ROSC, with 42% achieving circulation for at least 20 minutes versus 22% with placebo, a memorable separation that makes the trial hard to ignore.
- Patient-centered outcome gap: Thirty-day survival and favorable neurologic outcome did not improve, underscoring the central tension in IHCA research: better short-term physiology may not mean better long-term recovery.
- Resuscitation drug strategy: The study tested early methylprednisolone 40 mg plus vasopressin 20 IU after the first epinephrine dose, using a pragmatic intra-arrest approach rather than a post-ROSC bundle.
- Who the trial applies to: This was a multicenter, double-blind RCT in adults with IHCA who had already received epinephrine, which makes the findings directly relevant to real-world hospital arrest care.
- Surrogate endpoint caution: ROSC may matter for immediate resuscitation goals, but its value as a patient-oriented endpoint is debatable when neurologic outcome stays flat. We get into that tradeoff in the episode.
