초록

영상의학과에는 다양한 질병을 가진 환자들이 검사를 받는 곳으로 병원감염의 교차 오염이 될 가능성이 큰 부서이다. 특히 자기공명영상(MRI)검사는 다른 검사에 비해 검사시간이 오래 걸려 교차오염에 더욱더 노출이 될 수 있다. 이에 본 연구는 MRI검사장비의 소독실태를 파악하고, 환자와 접촉이 가장 많은 Head coil, 환자 고정용 Block, 밀폐된 공간인 Bore에서의 세균분포도를 파악 하였다. MRI 검사장비의 소독실태는 MRI실 근무자 150명을 대상으로 설문을 실시하였으며, 세균분포의 파악은 10 곳의 의료기관에서 측정하였다. MRI 장비의 세균 분포도결과 Staphylococcus, 등의 다양한 세균들이 발견되었다. MRI실 소독실태 파악결과 Head coil, Block, Bore의 소독은 잘 시행되는 것으로 나타났으며, 소독의 시기는 아침에 1회 소독을 가장 많이 시행 하는 것으로 나타났다. 또한 감염관리자에 따른 소독의 유, 무와 소독의 시기에서는 MRI실 검사자가 감염관리 할 때 잘 시행되는 것으로 나타났다. 환자를 검사한 후 교차오염을 방지하기 위하여 바로 적절한 소독제로 소독을 실시하여 교차오염을 방지하여야 할 것이다.

In radiology department, where patients with a variety of diseases receive their tests, there is a large possibility of cross contamination of nosocomial infection. Magnetic resonance imaging (MRI) tests take particularly more time than other tests do, which increases the possibility of being exposed to cross contamination. Therefore, this research examines the status of MRI equipment sterilization and investigates the bacterial distribution on head coils, which have the most frequent contact with patients, patient fixation blocks, and bores, which are confined spaces. The status of MRI equipment disinfection was examined by a survey targeting 150 employees, and the distribution of bacteria was measured in ten medical facilities. The result of bacterial distribution tests on MRI equipment showed various bacteria, including Staphylococcus, Acinetobacter, Sphingomona, Pantoea agglomeranss, Micrococcus, Bacillus, Saprophyticus, Brevundimona, and Myroidesspecies. The result of examining the stat us of MRI room disinfection showed that the disinfections of the head coil, block, and bore were implemented well, and the largest proportion was carried out once a day in the morning. The time and implementation of disinfection by the disinfection manager showed that they were implemented well when the manager was the MRI room examiner. The disinfection after examining a patient using an appropriate disinfectant is mandatory to prevent cross contamination.
