The Purpose of this study is for clinical nurses to be aware of the significance of prevention against
bacteriuria caused form foley catheterization, through probing variables related to the occurrence of
bacteriuria which appears as the most frequent occurring
infection, and try to lower
bacteriuria by applying to
nursing care at the clinical. For this study 46 patients with catheterization and the closed drainage system were sampled and investigated from among patients at Intensive Care Unit in Two hospitals affiliated to K University in Seoul. Those patients sampled had not shown
bacteriuria before foley catheterization. The research design is to explore the effectiveness of prevention against
bacteriuria in accordance with bladder irrigation and no bladder irrigation. Especially, the frequency of occurrence of
bacteriuria examined so as to compare the effectiveness of bladder irrigation depending on the type of foley
catheter between 2-lumen foley
catheter and 3-lumen foley
catheter. The results Were as follows. 1. The occurrence of
bacteriuria in patient with bladder irrigation was 21.7%, while in patient without bladder irrigation 26.1%. 2. The occurrence of
bacteriuria in patient without bladder irrigation according to duration of
indwelling catheter, was 4.3% after 48 h, 8.7% after 72 h and 21.7% after 96 h. 3. In case of 2-lumen foley
catheter the occurrence of
bacteriuria in patient with bladder irrigation was 0% after 72 h, and 4.35% after 96 h. In case of 3-lumen foley
catheter, the occurrence of
bacteriuria in patient with bladder irrigation was 13% after 48 h, 8.7% after 72 h and 4.3% after 96 h. 4. The occurrence of
bacteriuria according to duration of catheterization was 8.7% after 48h, 8.7% after 72 h and 15.2% after 96 h. In sex, female was 35% and male 15.4%. 5. The occurrence of
bacteriuria according to mental state was 15% in clear state, while 29.6% in
mental disorder. 6. In regard to a kind of microorganism induced
bacteriuria, Gram negative bacteria was 63.7%, Gram positive bacteria 36.3%.
