Fast Identification of Pathogen in the Setting of Hospital-acquired Pneumonia Using Ion Mobility Spectrometry

Pneumonia Clinical Trial

Official title:
Identification of Microbes Through Detection of Pathogen Specific Volatile Compound Patterns, Using Multi-capillary Column Coupled Ion Mobility Spectrometry (MCC-IMS) in the Setting of Hospital-acquired Pneumonia

Clinical Trial Summary

With this study the investigators want to determine, if a fast identification of germs, causing hospital-acquired infections of the lower respiratory tract, is possible through the use of MCC-IMS technology - a method that allows on time detection and identification of very small amounts of substances in gas samples. Therefore aspiration samples from the respiratory tracts of ventilated patients, which are suspected to develop such an infection, will be collected, cultivated and analyzed by MCC-IMS. The investigators want to determine if MCC-IMS diagnostic could be a faster alternative to conventional microbiological methods. The results of the MCC-IMS analyses therefore will be compared with results of conventional microbiological methods.

Clinical Trial Description

In this clinical feasibility study it is to be investigated if MCC-IMS analyses over clinical samples from ventilated critically ill patients could be a fast and secure alternative to conventional microbiological diagnostic methods in the identification of human pathogenic microbes in the setting of hospital-acquired pneumonia. Therefore aspiration samples from intubated and ventilated critically ill patients, which are suspected to develop such an infection, will be collected and cultivated for a short period of time. The headspace over these cultures will be analyzed using MCC-IMS - a technology that allows on time detection and identification of very small amounts of substances in complex and humid gas samples. Conventional microbiological investigations, including MALDI-TOF, will be carried out parallel to the MCC-IMS analyses. ;
