Tailoring blood flow during surgery may cut deadly complications

NCT ID NCT05648279

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This large international trial tested whether keeping a patient's blood flow (cardiac index) at their own personal baseline during major abdominal surgery reduces serious complications. Over 1,100 high-risk adults aged 45 and older took part. The goal was to see if this personalized approach lowers the chance of kidney injury, heart injury, severe infections, or death within a week after surgery compared to standard care.
