First seen Jun 26, 2026 · Last updated Jul 15, 2026 · Updated 3 times
Summary
This study looked at whether using a forced-air warming blanket during knee replacement surgery helps prevent hypothermia (low body temperature) and related problems like shivering. Researchers compared 240 patients who either got the warming blanket or standard care. The goal was to see if the device keeps patients warmer and improves recovery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Forced-air warming device
- What this could lead to
- If effective, forced-air warming could become a standard practice to prevent hypothermia and improve recovery after knee replacement surgery.
- What could go wrong
- This is a completed historical control study, not a randomized trial, so results may be less reliable. The intervention is a device, not a drug, so benefits are limited to warming and may not affect major outcomes.
