A neck artery may reveal how the heart copes during lung surgery
NCT ID NCT07808749
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Lung resection surgery changes pressure inside the chest, which can reduce blood returning to the heart and lower cardiac output. Researchers at the University of Valencia are observing 50 patients scheduled for thoracoscopic lung resection to see how a noninvasive ultrasound measure called corrected carotid flow time responds to anesthesia, body position, one-lung ventilation, chest opening, and fluid given during surgery. They also test whether this measure can predict which patients respond to fluids and tolerate lung recruitment maneuvers. The study tracks these changes rather than testing a treatment.
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 carotid flow time tracks cardiac output reliably, doctors could use a simple neck ultrasound to guide fluid and ventilation decisions during lung surgery without invasive monitoring.
- What could go wrong
- This is a small observational study of 50 patients at one hospital, so any link between carotid flow time and cardiac output may not hold in other patients, surgeries, or hospitals. It cannot prove that acting on these measurements improves outcomes.
