Infraclavicular axillary vein collapsibility to predict who will respond to fluids in sepsis

Official title: Infraclavicular Axillary Vein Collapsibility Index as a Predictor of Fluid Responsiveness in Spontaneously Breathing Patients in Sepsis-related Acute Circulatory Failure: a Prospective Observational Study

Run by Ain Shams University · NCT07507877 · Data updated 2026-11-12

This trial tests whether the infraclavicular axillary vein collapsibility index can tell which adults with sepsis who are breathing on their own will increase their blood flow after getting IV fluids.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults (≥18 years) with sepsis who are breathing without mechanical ventilation, meet at least two SIRS criteria, and show clinical signs of acute circulatory failure.

Probably not a fit

Mechanically ventilated patients, children under 18, or patients without sepsis-related circulatory failure are unlikely to benefit from this technique as studied here.

What this trial studies

This observational study measures the infraclavicular axillary vein collapsibility index using ultrasound in spontaneously breathing adult patients with sepsis and clinical signs of acute circulatory failure. Investigators will compare the vein collapsibility measurements with patients' fluid responsiveness after fluid administration to determine predictive value. The protocol enrolls adults meeting at least two SIRS criteria and excludes mechanically ventilated patients and those under 18. The goal is to validate a noninvasive alternative to inferior vena cava measurements for guiding resuscitation decisions.

Why it matters

Potential benefit: If successful, this approach could help clinicians decide who needs IV fluids and avoid fluid overload by providing a noninvasive bedside predictor of fluid responsiveness.

How similar studies have gone: Previous work has established inferior vena cava collapsibility as a predictor of fluid responsiveness, and axillary or other peripheral venous collapsibility measures have shown promising but less well-validated results.
