|
The study was performed to investigate the bacteriological contamination of portable digital radiography system and their detectors in a university hospital. CNS and VRE were detected in the samples collected from vinyl cover on detectors used for the infection control patients. On the other hand, no bacteria was detected in the samples collected from detectors with vinyl cover removed. In the series of imaging of patients from general wards, no bacteria was detected from the patient 1. However, CNS was detected from the patients 2 and 3, CNS and Enterococcus faecalis detected from the patient 4, CNS and Enterococcus casseliflavus detected from the patient 5, and CNS, Enterococcus casseliflavus, and Klebsiella pneumoniae all detected from the patient 6. CNS and Enterococcus faecium were detected in the controller handle of collimator. Also, CNS was detected from the handle of detector and exposure switch. In the treatment gloves of the radiological technologist after the imaging, CNS, Enterococcus gallinarum, and Klebsiella pneumoniae were detected. Therefore, it is recommended for DR portable to take images after sterilizing the detector after taking each image and to use disposable vinyl covers on detectors to remove after imaging. And treatment gloves must be changed after each imaging. Also, hospital infection via portables must be prevented by complete sterilization of the controller handles of collimator which are in frequent contact during imaging and infection education of employees.
