Can a simple ultrasound predict organ failure in septic shock?
NCT ID NCT07698834
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study investigates whether Doppler ultrasound, a non-invasive imaging technique, can measure blood flow to the gut in patients with septic shock. The goal is to see if these measurements correlate with how well the body clears lactate (a marker of tissue oxygen debt), the severity of organ dysfunction, and whether patients can tolerate tube feeding. The study will enroll 80 adults in the ICU with septic shock and follow them for up to 72 hours.
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 non-invasive way to monitor gut health in septic shock, potentially improving care decisions.
- What could go wrong
- This is an observational study with 80 patients, so results may not apply broadly. Ultrasound quality can vary, and the technique may not reliably predict outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 1\. Adult patients (≥18 years). 2. ICU admission with septic shock (Sepsis-3 definitions). Exclusion Criteria: \- 1. Advanced chronic liver disease. 2. Portal vein thrombosis. 3. Mesenteric ischemia (or clinical suspicion strongly suggesting it). 4. Severe right-sided heart failure. 5. Pregnancy. 6. Morbid obesity or any condition causing poor/unsafe ultrasound acoustic window. 7\. Intra-abdominal conditions preventing adequate Doppler assessment. 8. Limitation of care / do-not-resuscitate orders. 9. Pre-existing major gastrointestinal bleeding/obstruction if that is relevant to enteral feeding intolerance outcomes in your ICU.
