Using alveolar dead space measurements to predict organ failure in severe sepsis patients

Alveolar Dead Space as Predictor of Multi-organ Failure and Mortality in Medical Intensive Care Patients With Sepsis Requiring Mechanical Ventilation

Observational The University of Texas Health Science Center, Houston · NCT01315782

This study is testing if measuring a specific lung space in severe sepsis patients on ventilators can help predict if they will experience organ failure.

What this trial studies

This observational study aims to investigate the changes in alveolar dead space in critically ill patients suffering from severe sepsis who require mechanical ventilation. By utilizing advanced ventilators with microprocessors, the study seeks to rapidly calculate alveolar dead space with minimal intervention. Patients will be monitored daily for the first 48 hours and then weekly for up to two weeks during their ICU stay. The goal is to determine if these measurements can serve as predictors for multi-organ failure.

Who should consider this trial

Good fit: Ideal candidates are adults with severe sepsis or septic shock who are on mechanical ventilation and are enrolled within the first six hours of ICU admission.

Not a fit: Patients with terminal diseases, those on hospice care, or those with COPD may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prediction and management of organ failure in patients with severe sepsis.

How similar studies have performed: While the approach of measuring alveolar dead space is established, the specific application in predicting organ failure in severe sepsis is novel and has not been extensively tested.
