Can a quick ultrasound predict dangerous blood pressure drops during surgery?
NCT ID NCT07742904
First seen Aug 03, 2026 · Last updated Aug 12, 2026 · Updated 3 times
Summary
This study is testing whether two different ultrasound measurements can predict a sudden drop in blood pressure that sometimes happens when anesthesia is given. The trial will include adults aged 40 to 70 with intestinal obstruction who are having exploratory abdominal surgery. Researchers will compare the accuracy of measuring the heart's stroke volume versus the collapsibility of the inferior vena cava, both done with a standard ultrasound, to see which better forecasts this complication.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Transthoracic echocardiography (ultrasound of the heart and major blood vessels) to measure stroke volume and inferior vena cava collapsibility index
- What this could lead to
- If one method proves more accurate, it could help anesthesiologists better predict and prevent dangerous blood pressure drops during surgery, improving patient safety.
- What could go wrong
- This is a single-center study with a relatively small number of participants, and results may not apply to all patients or settings. The ultrasound measurements can be technically challenging and may not always be reliable.
