Finger sensor and ultrasound may predict blood pressure danger in shoulder surgery
NCT ID NCT07572539
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at whether two simple, non-invasive tests can predict when a patient's blood pressure will drop dangerously during shoulder surgery performed in the 'beach chair' position (sitting upright). The tests are a finger sensor that measures blood flow and an ultrasound that checks the main vein in the belly. Researchers will study 70 adults having elective shoulder arthroscopy to see how accurate these tests are. The goal is to help doctors prevent complications during surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could give doctors a simple, non-invasive way to predict and prevent dangerous blood pressure drops during certain types of shoulder surgery.
- What could go wrong
- This is a small, early observational study, not a treatment trial. The measurements may not prove accurate enough to use in routine practice.
