Sound waves aimed at spleen may tame deadly inflammation in septic shock
NCT ID NCT06990295
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a non-invasive ultrasound device, aimed at the spleen, can safely reduce dangerous inflammation in people with septic shock. Septic shock is a life-threatening condition where the body's response to infection causes organ damage. Forty adults in the intensive care unit will either receive standard care alone or standard care plus twice-daily ultrasound treatments for five days. Researchers will measure changes in inflammatory markers and track recovery, organ function, and survival.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥ 18 years, regardless of sex * Diagnosed with septic shock according to Sepsis-3 criteria: Sequential Organ Failure Assessment (SOFA) score ≥ 2 and requiring vasopressor support to maintain a mean arterial pressure (MAP) ≥ 65 mmHg. * Admitted to the ICU within 24 hours of septic shock diagnosis * Expected to require intensive care for at least 72 hours * Informed consent obtained from the patient or legal representative Exclusion Criteria: * Known pregnancy or breastfeeding * Participation in another interventional clinical trial within 30 days * Known immunodeficiency or ongoing immunosuppressive therapy * Malignancy with life expectancy \< 6 months * Contraindications to focused ultrasound (e.g., splenic trauma, splenectomy, local skin infection) * Do-not-resuscitate (DNR) order or expected death within 24 hours * Any other condition deemed unsuitable for participation by the investigators
