Investigating kidney blood flow changes after traumatic injury

Renal Perfusion and the Development of AKI Following Traumatic Injury - A Longitudinal Observational Cohort Study

Observational King's College Hospital NHS Trust · NCT06917053

This study looks at how blood flow to the kidneys changes in patients who have had serious injuries and are at risk for kidney problems after receiving blood products.

What this trial studies

This observational study aims to explore how traumatic hemorrhagic shock affects renal microcirculatory perfusion in patients who have experienced traumatic injuries. By utilizing advanced imaging techniques such as ultrasound and sublingual incident dark field videomicroscopy, the study will assess intra-renal perfusion changes in the early hours following ICU admission. The research focuses on patients who have received blood products and have elevated lactate levels, indicating a risk for acute kidney injury (AKI).

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who have been admitted to the ICU within 24 hours of a traumatic injury and have received blood products.

Not a fit: Patients with known chronic kidney disease stage 4 or end-stage renal failure, as well as those with un-survivable injuries, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of acute kidney injury in trauma patients, potentially reducing mortality rates.

How similar studies have performed: While there is existing knowledge regarding AKI in septic shock patients, this specific investigation into renal perfusion changes following traumatic hemorrhagic shock is relatively novel.
