Scientists track hidden body changes during sepsis after surgery
NCT ID NCT07442552
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how sepsis (a severe infection) changes the body's inflammation, blood clotting, heart function, and certain genetic markers in 40 adults after major abdominal surgery. Researchers compare patients who develop sepsis with those who do not, using blood tests and heart scans before and within 24 hours after surgery. The goal is to better understand these changes and find early warning signs of sepsis.

Who is studied
The study population includes adult patients (≥18 years) undergoing elective or emergency major abdominal surgery at a single academic university hospital. Eligible patients must be hemodynamically stable in the preoperative period, able to provide written informed consent, and have biological samples available both before surgery and within 24 hours postoperatively. A total of 40 patients are prospectively enrolled and followed during the perioperative period only. The patients are devided into septic or non-septic.
