Ultrasound might predict which heart surgery patients face catheter insertion trouble
NCT ID NCT04730479
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This study looks at whether measuring the size of the radial artery with ultrasound before surgery can predict if placing a small tube (catheter) in the wrist will be difficult. It involves 330 adults scheduled for heart or aortic surgery. The goal is to see if ultrasound measurements can help doctors anticipate and avoid multiple puncture attempts.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ultrasound measurement of the radial artery's internal diameter
- What this could lead to
- If ultrasound can reliably predict which patients are likely to have catheter insertion problems, it could help doctors choose better insertion sites or techniques in advance, reducing complications and improving patient comfort.
- What could go wrong
- This is an observational study, so it won't directly test a new treatment. The predictive value of ultrasound may not be high enough to change clinical practice, and results may not apply to all patient groups or settings.
