A simple Warm-Up before surgery may help tissues breathe better

NCT ID NCT07702487

First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time

Summary

This observational study looks at whether briefly warming adults before elective kidney removal surgery (nephrectomy) can lower blood lactate levels — a sign of how well tissues are getting oxygen — and improve recovery. Researchers will compare patients who receive routine prewarming with those who do not, tracking lactate, blood pressure, heart rate, ICU stay, and complications. No extra tests or procedures are added beyond standard care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
preoperative active warming using a device applied to the body surface for 10-15 minutes before anesthesia
What this could lead to
If prewarming is linked to lower lactate and fewer complications, it could support a simple, low-cost change to routine surgical care.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The prewarming decision is made by the care team, not randomly assigned, which may bias results.
