Temperature management during long abdominal surgeries

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In prolonged abdominal surgeries, patients frequently become hypothermic, which can increase bleeding, infection risk, and hospital stay. The trial compares two warming strategies: standard forced-air warming alone versus forced-air warming plus warming intravenous fluids to 39 °C. It is a single-center, randomized, parallel-group, open-label pilot in Saint Petersburg, enrolling adults undergoing 3+ hour abdominal procedures. Outcomes include perioperative temperatures, hemodynamics, fluid use, lactate, inflammatory markers, and early organ function scores. All participants receive general anesthesia with a standardized warming protocol; however, only the intervention group receives actively warmed IV fluids.
