New device aims to prevent dangerous blood pressure drops during surgery
NCT ID NCT07554599
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a non-invasive device called the Hypotension Prediction Index (HPI) in 60 elderly patients (ages 65-90) undergoing shoulder surgery in a beach chair position. The device predicts when blood pressure might drop dangerously low, allowing doctors to intervene early. The goal is to reduce brain oxygen drops and complications like stroke or kidney injury.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- non-invasive Hypotension Prediction Index (HPI) device
- What this could lead to
- If successful, this device could help doctors prevent dangerous drops in blood pressure during surgery, reducing the risk of brain injury and other complications in elderly patients.
- What could go wrong
- This is a small, early-stage trial with only 60 participants, so results may not apply to all patients. The device may not reliably predict hypotension or improve outcomes.
