Minimal Sedation After Out-of-Hospital Cardiac Arrest
Official title: Effect of Early Discontinuation of Sedation on Biomarkers of Hypoxic-Ischemic Brain Injury After Out-of-Hospital Cardiac Arrest: A Prospective Randomized Non-Inferiority Trial
Run by University Medical Centre Ljubljana · NCT07895771 · Data updated 2026-11-12
This study tests whether stopping continuous sedation right after return of circulation is as safe as keeping patients sedated in the early hours after OHCA.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older who have had an OHCA with ROSC and remain comatose (FOUR motor score <4 or no verbal response).
✕Probably not a fit
Patients with rapid improvement, severe pre-existing neurological impairment, or conditions meeting exclusion criteria (e.g., hypothermia at randomization, high vasopressor needs) may not benefit.

What this trial studies
This is a single-centre, open-label randomized non-inferiority trial enrolling comatose adults after out-of-hospital cardiac arrest. Participants are assigned to either a minimal sedation strategy (no continuous sedation unless needed) or standard continuous sedation for at least 36 hours, with analgesia and active temperature management in both groups. The primary endpoint is serum NSE at 72 hours, with secondary outcomes including mortality, neurological status at discharge, duration of mechanical ventilation, and ICU length of stay. The study uses a web-based randomization system and follows a structured protocol for hyperthermia, shivering, seizures, and EEG monitoring over about two years. Lead site is University Medical Centre Ljubljana, Slovenia.
Why it matters
Potential benefit: If successful, the minimal sedation approach could shorten time on ventilation and ICU stay without increasing brain injury, potentially improving recovery after OHCA.
How similar studies have gone: Previous sedation strategies after OHCA show mixed results; this trial addresses a novel non-inferiority question about minimizing sedation, with prior data suggesting possible safety in carefully managed patients but not definitive.
