Monitoring brain activity and oxygen levels in ARDS patients in the ICU

Depth of Sedation and Its Impact on Cerebrovascular Reactivity in Acute Respiratory Distress Syndrome: a Pilot Analysis

Observational University of Manitoba · NCT05847634

This study is testing if new non-invasive methods can help doctors find the right level of sedation for patients with acute respiratory distress syndrome in the ICU by monitoring their brain activity and oxygen levels.

What this trial studies

This study investigates the feasibility of using non-invasive monitoring techniques, specifically processed electroencephalography (EEG) and near-infrared spectroscopy (NIRS), to assess the optimal depth of sedation in patients with acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU). The research aims to determine how these monitoring methods can help minimize the correlation between brain oxygenation and sedation levels. Data collected will include demographic information, medical history, and sedation dosages, allowing for a comprehensive analysis of sedation effects on cerebrovascular reactivity in ARDS patients.

Who should consider this trial

Good fit: Ideal candidates are adult patients admitted to the ICU with confirmed ARDS requiring deep sedation and/or neuromuscular blockade.

Not a fit: Patients who have been in the ICU for more than 24 hours or are deemed to have imminent death will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved sedation management in ARDS patients, enhancing their recovery and outcomes.

How similar studies have performed: While this approach is novel in the context of ARDS, similar monitoring techniques have shown promise in other critical care settings.
