Identifying lipid biomarkers in critically ill patients on mechanical ventilation

Oxidative Lipidomic Biomarkers During Mechanical Ventilation in Critically Ill Patients (OXY-BAL).

Observational Ohio State University · NCT05412810

This study is trying to find out if certain fats in the body can help understand how well critically ill patients on mechanical ventilation are responding to high levels of oxygen.

What this trial studies

This observational study aims to identify and measure the levels of oxidized lipids and lipid mediators in critically ill patients undergoing mechanical ventilation with high oxygen supplementation. Patients will receive oxygen at a fraction of inspired oxygen (FiO2) of 0.5 or greater for at least 90 minutes, and two sequential mini bronchoalveolar lavages will be performed 24 hours apart. The study will utilize mass spectrometry lipid chromatography to analyze the lipid profiles and correlate them with clinical data to determine optimal oxygenation levels and their effects on inflammation and lung injury.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who require mechanical ventilation in an intensive care unit for at least 48 hours.

Not a fit: Patients who only need mechanical ventilation for procedures or have chronic respiratory failure prior to admission may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved oxygenation strategies that minimize lung injury in critically ill patients.

How similar studies have performed: While the approach of using oxidative lipidomics in this context is novel, similar studies have shown promise in understanding lipid mediators in inflammatory conditions.
