Abstract

The authors reviewed 13,7099 medical records to obtain estimates of frequncy, causion, and pathogen of gram negative bacilli that were arised nosocomial infection among 26,220 pateints who were admitted in Chung-Ang University Hospital during the period from January, 1982 to December, 1985.
The results were follows;
1) 196 strains from 174 pateints were isolated gram negative bacilli from hospital infection. Above data were corresponding to 0.81 of admitted pateints in, our hospital, and that was composed of 1.3 % of all cultured GTN that sent to our clinical microbiology laboratory (Table 1).
2) The most frequent sources of isolates were specimen from urine (520o), sputum
(261), and pus (171) in orders (Table 3).
3) The major departments occured nosocomial infection are NeuroSurgery in 71, General Surgery in 27, Internal Medicine in 26, Orthopedic Surgery in 20, and Urology in 19 patients respectively (Table 4).
4) The mode of infection through the Foley catheterization were 61.21 in urinary
tract and 15.31 tracheostomy had done in respiratory tract (Table 5).
5) Nosocomial infections were developed on 14th or 18th day of hospitalization.
And the frequent risk predisposing disease were Intracranial and subarachnoidal
hemorrhage (49.8%), and various malignant diseases (14.51) in urinary tract
infection, and Burns were first rank in wound infection(Table 7).
6) The most commonly pathogen responsible for nosocomial infection were included
E. coli(31 strain), Klebsiella sp. (19 strain), and Pseudomonas SP. (14 strain),
which also showed mainly isolated from urine, sputum, and pus in orders
(Table 8).
7) In susceptibility test, Pseudomonas aeruginosa were susceptible to only Amikacin, and Klebsiella sp. showed sensitive to Cefotaxime, Cefoperazone. Especially E. coli revealed than 50% sensitive to Kanamycin, gentamicin, Amikacin, Cefotaxime, and Cefoperazone(Table 9).
