Ultrasound-Guided Beta-Blockers: a new hope for septic shock?
NCT ID NCT07313605
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tests whether using ultrasound to guide treatment with the beta-blocker esmolol is feasible in patients with septic shock. Septic shock is a life-threatening condition where infection causes very low blood pressure and a dangerously fast heart rate. The trial will enroll 100 adults and compare those receiving esmolol (to slow the heart) against standard care, monitoring for 90 days. The main goal is to see if a larger, definitive trial can be done successfully.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Esmolol (a beta-blocker drug given intravenously to slow heart rate)
- What this could lead to
- If this pilot succeeds, it could pave the way for a larger trial testing whether beta-blockers guided by ultrasound improve survival in septic shock.
- What could go wrong
- This is a small, early-phase feasibility study, not designed to prove benefit. Beta-blockers can be harmful if the heart is not well-filled or functioning poorly, and results may not generalize.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age 18 years or older 2. Within 24 hours of diagnosis of septic shock based on Sepsis-3 criteria (requirement for vasopressors to maintain organ perfusion, lactate greater than 2 mmol/L, suspected or confirmed infection) 3. Within 72 hours of ICU admission 4. Tachycardia with heart rate 100 beats per minute or greater, defined as either sinus tachycardia or atrial fibrillation/flutter Exclusion Criteria: 1. Known allergy to beta-blockers 2. Second or third-degree heart block without a functioning pacemaker 3. Acute bronchospasm or status asthmaticus 4. Pregnancy 5. Patient receiving extracorporeal membrane oxygenation 6. Decision to limit life-sustaining therapies 7. Untreated pheochromocytoma 8. Fluid-responsive patients as determined by POCUS assessment 9. Moderate to severe right ventricular and/or systolic left ventricular dysfunction as determined by POCUS assessment 10. Patient already receiving calcium channel blocker or beta-blocker therapy
