Is this trial a fit for you?

Likely a good fit

Adults (≥18) undergoing abdominal, orthopedic, or vascular major non-cardiac surgery under general anesthesia with expected duration >2 hours and at least moderate comorbidity (ASA II or higher).

Probably not a fit

Patients without the identified risk factors or those undergoing procedures outside the included surgical categories may not experience a benefit.

What this trial studies

This post-hoc analysis looks at how patient characteristics and intraoperative management relate to postoperative morbidity and mortality in adults undergoing major non-cardiac surgery lasting more than 2 hours. It uses data from a multicenter cohort focused on tissue perfusion during surgery, and aims to identify determinants of complications in a large real-world population. The study is observational and analyzes existing data rather than testing a single intervention. Results could help tailor perioperative care to reduce risks for high-risk patients.

Why it matters

Potential benefit: Finding actionable risk factors could help clinicians refine perioperative strategies to lower postoperative complications.

How similar studies have gone: Previous studies have explored single-parameter effects; this analysis extends understanding by examining determinants across a large, real-world population in an observational design.
