Nosocomial infection is important in the management of the nursing care in the I.C.U. and has been found to be related with the airborne microbes contamination.
The purpose of this study is to identify the differences of the airborne microbes between I.C.U. of 3 hospitals, nursing units in the I.C.U., days and times and to identify the difference in the types of microorganisms between I.C.U. of 3 hospitals, nursing units in I.C.U., days and times.
The survey has been determined from April 4. to April 18. 1983 and use of three general hospitals in Gwang ju City according to R. Koch´s methods for guantative samplings of airborne microbes and the results of this study were reviewed in a statistical method.
The results abtained were as follows,
1. There was a significant difference of airborne microbes between I.C.U. of 3 hospitals. (F=3.15, p<0.05)
2. There was a significant difference of airborne microbes between 3 nursing units in I.C.U. (F=3.15, p<0.05)
3. There was not a significant difference of airborne microbes between Monday, Wednesday and Saturday. (F=3.15, p>0.05)
Monday : 12.96 colonies
Wednesday : 18.54 colonies
Saterday : 8.42 colonies
4. There was not a significant difference of airborne microbes between AM 8:00, PM2:00 and PM 8:00. (F=3.15, p>0.05)
AM 8:00: 18.71 colonies
PM 8:00: 9.92 colonies PM2:00: 11.29 chlonies
5. There was a significant difference in the types of airborne microbes between I.C.U. of 3 hospitals. (F=7.27, p<0.01)
6. There was a significant difference in the types of airborne microbes between 3 nursing units in the I.C.U. (F=8.07, p<0.01)
7. There was not a significant difference in the types of airborne microrobes between Monday, Wednesday and Saturday. (F=3.36, p>0.01)
8. There was a significant difference in the types of airborne microbes between AM 8:00, PM 2:00 and PM 8:00. (F=5.36,p<0.05)
9. 958 colonies were divided into more 15 types and the classification was as follows,
Gram positive cocci (421 colonies) 43.9%
Gram negative bacillus (182 colonies) 19.0%
Fungus (54 coronies) 5.6%
Gram positive bacillus (44 colonies) 4.6%
Gram negative cocci (1 colonies) 0.2%
Others(256 colonies) 26.7%
