Skin blood flow and capillary refill monitoring in ICU patients with circulatory failure
Official title: Effects of Therapeutic Hemodynamic Interventions on Peripheral Perfusion in Intensive Care
Run by Assistance Publique - Hôpitaux de Paris · NCT06384287 · Data updated 2026-11-12
This study will see if capillary refill time and local skin blood flow change after routine treatments (fluids, vasopressors, or inotropes) in ICU patients with acute circulatory failure from sepsis or heart failure.

Is this trial a fit for you?
✓Likely a good fit
ICU patients with acute circulatory failure due to sepsis or cardiac failure who are receiving a fluid challenge, vasopressor, or inotropic therapy and who do not have agitation, hemorrhagic shock, or severe skin lesions.
✕Probably not a fit
Patients with hemorrhagic shock, severe skin lesions, or agitation that prevents reliable peripheral measurements, and patients treated outside the study ICU, are unlikely to benefit.

What this trial studies
Microcirculatory abnormalities are a major driver of organ hypoperfusion in septic and cardiogenic shock, and capillary refill time (CRT) is an easy bedside tool linked to outcomes. This prospective observational study will record the kinetics of CRT and local skin blood flow before and after routine hemodynamic interventions such as fluid challenges, vasopressor adjustments, or inotropic drugs. Eligible patients are those in the medical intensive care unit with acute circulatory failure related to sepsis or cardiac failure, excluding those with agitation, hemorrhagic shock, or severe skin lesions. Measurements will be performed as part of usual care at Saint-Antoine Hospital to describe how peripheral perfusion responds to common treatments.
Why it matters
Potential benefit: If successful, the results could help clinicians use changes in capillary refill time and skin blood flow to determine whether fluids or vasoactive drugs are improving tissue perfusion and to guide more targeted resuscitation.
How similar studies have gone: A recent randomized trial reported promising results for CRT-guided resuscitation, but the specific effects of different hemodynamic drugs on CRT and skin blood flow remain underexplored.
