Ultrasound inside the lungs could spot deadly clots in ICU patients
NCT ID NCT04047784
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study is testing whether a special ultrasound scope (EBUS) can diagnose acute pulmonary embolism (a blood clot in the lung) in critically ill patients in the ICU. These patients often cannot undergo standard CT scans because they are too unstable or have kidney problems. The study will enroll 60 intubated adults and compare EBUS findings to CT results when available, and track patient outcomes. If EBUS proves accurate, it could offer a faster, bedside way to diagnose life-threatening clots.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Endobronchial ultrasound (EBUS) device
- What this could lead to
- If successful, EBUS could provide a bedside tool to quickly diagnose dangerous blood clots in the lungs of ICU patients who are too unstable for standard scans.
- What could go wrong
- This is a small pilot study (60 patients) with no control group, so results may not be definitive. EBUS is not yet proven for this use, and the procedure carries risks like airway bleeding or low blood pressure.
