P-16 Assessment of muscle oxygen saturation in the early phase of extracorporeal life support

Introduction. Patients with extracorporeal life support (ECLS) may be at risk of inadequate tissue perfusion and oxygenation that leads to multiple-organ dysfunction. Near-infrared spectroscopy has emerged in recent years as a non-invasive tool for monitoring peripheral oxygenation (StO2) in various tissues, including muscle. Using a dynamic vascular occlusive test (VOT), StO2 abnormalities were identified during septic shock and severe trauma, suggesting microvascular dysfunction [1-3]. We wondered whether StO2 abnormalities could exist during the early phase of ECLS.
