Pseudomonas Aeruginosa Infection, Rapid Detection
Conditions
Brief summary
The aim of this study is to observe specimens of bronchoalveolar lavage fluid from patients using a reflection enhanced dark-field scattering microscopy. By observing parameters such as the size, morphology, scattering intensity, and movement speed of pathogens, combined with the clinical characteristics of patients, a rapid diagnosis of Pseudomonas aeruginosa infection can be made. At the same time, the bronchoalveolar lavage fluid samples of patients infected with Pseudomonas aeruginosa before and after treatment were compared, and the quantity and vitality of Pseudomonas aeruginosa were observed to judge the efficacy of antibiotics.
Interventions
We will perform bronchoscopy and collect bronchoalveolar lavage fluid (BALF)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The size of pathogens | From enrollment to the end of treatment at 2 weeks | Measure the size of pathogens |
| scattering intensity of pathogen | From enrollment to the end of treatment at 2 weeks | Determine the shape of pathogens through scattering intensity |
| movement speed of pathogens | From enrollment to the end of treatment at 2 weeks | Measure the movement speed of pathogens, such as flagellates like Pseudomonas aeruginosa, which have a fast movement speed |
