Using advanced imaging to study biofilm in endotracheal tubes for critically ill patients

Dynamic Full-field Optical Coherence Tomography for Endotracheal Tube Biofilm Characterization in Critically Ill Patients

Observational Centre Hospitalier Universitaire Dijon · NCT06379139

This study is trying to understand the germs that build up in breathing tubes used for critically ill patients to see if it can help prevent pneumonia caused by ventilators.

What this trial studies

This observational study aims to characterize the biofilm present in endotracheal tubes used in critically ill patients, which is linked to ventilator-associated pneumonia (VAP). By employing Dynamic Full-Field Optical Coherence Tomography, the study seeks to provide a detailed analysis of the microbiological structures within the biofilm. The findings could lead to improved strategies for managing and preventing VAP in intensive care settings. The study includes patients who have been mechanically ventilated for at least two days and have provided informed consent.

Who should consider this trial

Good fit: Ideal candidates are critically ill patients over 18 years old who have been on mechanical ventilation for at least two days.

Not a fit: Patients who are unable to provide informed consent or whose endotracheal tube samples cannot be collected will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prevention and management strategies for ventilator-associated pneumonia in critically ill patients.

How similar studies have performed: While the approach of using advanced imaging techniques for biofilm characterization is relatively novel, previous studies have indicated the importance of targeting biofilm in preventing VAP.
