A Study on the Degree of Contamination of Air and Materials in a Hospital
병원내 공기오염과 물품의 항균에 대한 상태조사
Abstract
The incidence of hospital infection has been seriously increased in the general hospital in recent years. This study was performed on hospital air and materials in a General Hospital in Seoul from June to December in 1980. The results were as follows: 1. Air sampling was done in multiple strategic areas by exposing standard petridishes for 5 minutes. There was a significant difference of airborne microbe between places. ($F._{99}$ = 3.2, p < 0.01). 2. The mean colony count was 8.6$\pm$6.2 colonies / plate / 5 minutes. 3. Gram stains of colony in air sampling were Gram (+) cocci 66.5%. Gram (+) rod 18.4%, Gram (-) cocci 1.3%, Gram (-) rod 8.7% Fungus 4.5%. 4. For the evaluation of sterilization of steam sterilizer and ethylene oxide gas sterilizer, biological monitoring were done by commercial spore strip. Positive culture was obtained in 2 out of 41 tests on 3 steam sterilizers, and in 3 out of 13 tests on ethylene oxide gas sterilizer. 5. Product sampling and culture were done for 2 kinds of disinfectants and 30 sets of various operation package or dressing materials. Positive culture was obtained in one disinfectants.
