Can a quick ultrasound prevent dangerous blood pressure drops in hip surgery?
NCT ID NCT07669376
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether an ultrasound measurement of a large vein near the heart (the inferior vena cava) can predict when a patient's blood pressure will drop dangerously during hip replacement surgery. Researchers will measure this vein's flexibility before cement is used to secure the new hip joint. The goal is to find a cutoff value that warns doctors ahead of time. Thirty adults having elective hip replacement under general anesthesia will take part.
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 ultrasound test to predict and prevent severe blood pressure drops during hip replacement surgery.
- What could go wrong
- This is a very small, early study with only 30 participants. The ultrasound measure may not reliably predict blood pressure changes in all patients.
