Is this trial a fit for you?

Likely a good fit

Adults aged 18-75 undergoing surgical repair for acute Stanford type A aortic dissection, able to provide informed consent.

Probably not a fit

Patients with very limited life expectancy, severe preoperative liver or renal failure, COPD/asthma, or immunosuppression may not benefit and could be excluded from participation.

What this trial studies

This is a multicenter, double-blind, randomized controlled trial in adults undergoing repair for acute Stanford type A aortic dissection. Participants receive either intravenous sivelestat sodium for 72 hours or a placebo, in addition to standard ICU care. The study measures organ function using the SOFA score from day 0 to day 5 and looks at 28-day clinical outcomes. The trial aims to determine whether sivelestat can reduce organ failure and improve recovery compared with placebo. Recruitment involves several hospitals in China and Hong Kong, with strict eligibility criteria to exclude patients with limited life expectancy or significant preoperative organ dysfunction.

Why it matters

Potential benefit: If successful, sivelestat could help preserve organ function and improve recovery after surgery for type A aortic dissection.

How similar studies have gone: Previous studies in similar contexts have explored neutrophil elastase inhibitors for organ protection, with mixed results; this trial tests effectiveness in a rigorous randomized setting.
