Abstract

본 연구는 IP 카세트를 이용하는 이동촬영 장비의 세균오염도를 조사하여 이동촬영으로 인한 병원 감염을 예방하고 감염교육의 기초자료를 제공하고자 실시하였다. 결과는 IP Cassette 1번에서 CNS, VRE가 검출되었다. 2번에서는 CNS, 3번에서는 CNS, Pseudomonas aeruginosa, 4번에서는 CNS, 5번에서는 CNS, Bacillus sp., 6번에서는 Enterococcus faecium이 검출되었다. 영상판독기에서는 Enterococcus faecium, Bacillus sp., 장비 이동 손잡이에서 Acinetobacter baumannii, 조작버튼에서는 Bacillus sp., 조사야 조절 손잡이에서는 CNS, Bacillus sp., X-선 발생 스위치에서는 Acinetobacter baumannii, 바코드기 에서는 CNS가 검출되었다. IP Cassette 이동테이블에서는 Bacillus sp. Acinetobacter baumannii, 납 앞치마에서는 CNS, Bacillus sp.가 검출되었다. 방사선사가 촬영 중 착용한 의료용 장갑에서는 Acinetobacter baumannii, CNS가 검출 되었다. 따라서 IP Cassette는 사용 후에는 반드시 소독하고 재사용하며, 영상판독기, IP 이동테이블은 오염된 IP Cassette를 통해 세균이 전파될 수 있으므로 사용 후에는 소독을 실시해야 한다. 환자와 직접 접촉하는 의료용 장갑도 1회 사용 후 교체하고 촬영 시 접촉이 많은 X-발생 스위치, 납 앞치마도 철저히 소독하여 이동촬영으로 인한 감염을 예방하여야 한다. The purpose of this study is to prevent infection in the hospital by computed radiography portable and to provide basic data on infection-related education by investigating bacterial contamination level of computed radiography portable equipment using IP cassette. The results suggest that IP cassette No. 1 is infected with CNS and VRE, no. 2 with CNS, No. 3 with CNS and Pseudomonas aeruginosa, No. 4 with CNS, No. 5 with CNS and Bacillus sp., and No. 6 with enterococcus faecium. Enterococcus faecium and bacillus sp. were detected from the IP reader and Acinetobacter baumannii was detected on the mobile handle; Bacillus sp. on the control buttons, CNS and Bacillus sp. from the irradiation control handle, Acinetobacter baumannii on the x-ray generation switch, and CNS on the barcode scanner. In addition, Bacillus sp. Acinetobacter baumannii was found on the IP cassette mobile table and CNS and bacillus sp. were found on the lead apron. Acinetobacter baumannii and CNS were detected from the medical gloves worn by a radiological technologist during radiography. This suggests that IP cassette should be sterilized after use as it can hand over bacteria to IP reader and IP mobile table. Medical gloves that are in direct contact with patients should also be replaced after using them once and other supplies such as x-ray generation switch and lead apron should thoroughly be sterilized to prevent infection due to radiography as they are in a lot of contact with patients.
