Monitoring microvascular function in critically ill patients using near-infrared spectroscopy

Official title: Microvascular Monitoring in Circulatory Shock and Sepsis (MiMICSS): Prospective Observational Cohort Study

Run by University of Manitoba · NCT05985525 · Data updated 2026-11-12

This study is trying to see if a special light technology can safely check blood flow in the tiny blood vessels of critically ill patients in the ICU to help understand their health better.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are critically ill patients who are admitted to the ICU and receiving invasive mechanical ventilation.

Probably not a fit

Patients with a body mass index over 40 or those who are imminently dying may not benefit from this study.

What this trial studies

This observational study investigates the feasibility of using near-infrared spectroscopy (NIRS) to monitor microvascular function in critically ill patients admitted to the ICU. It involves the non-invasive application of NIRS monitors to assess skeletal muscle and brain microvascular metrics throughout the patient's ICU stay. Continuous vital signs and clinical data will be collected to explore the relationship between these metrics and ICU mortality, aiming to enhance understanding of microvascular health in sepsis and shock.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring of microvascular function, potentially enhancing patient outcomes in critical illness.

How similar studies have gone: While the use of NIRS in monitoring microvascular function is promising, this specific approach in critically ill patients is still being explored and may not have extensive prior success.
