Summary

This study tests a small sensor placed in reconstructed tissue after flap surgery. The sensor measures CO2 and temperature continuously for up to 10 days to detect early signs of poor blood flow. If it works, doctors could be alerted sooner and take action to save the tissue. About 56 adults having reconstructive flap surgery will take part.

What this could mean

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

Active substance: IscAlert CO2 and temperature sensor
What this could lead to: If successful, this sensor could help doctors catch blood flow problems early after reconstructive surgery, potentially reducing the need for emergency reoperations.
What could go wrong: This is an early-stage study with only 56 patients, so results may not apply to everyone. The sensor might cause minor bleeding or infection at the insertion site.
