Summary

This study aims to identify the key factors that lead to complications or death after major non-cardiac surgery. Researchers will analyze data from 350 adult patients who had abdominal, orthopedic, or vascular surgery lasting over two hours. The goal is to better understand these risks to improve future patient care.
