[Hospital infections with pseudomonas aeruginosa. II. Intensive care units (author's transl)].
72 newly admitted patients of three surgical intensive care units of the Medical School Hannover were examined bacteriologically for pseudomonas aeruginosa for a period of 7 months. A total of 810 specimens was examined during therapy. 95 strains of pseudomonas aeruginosa were isolated in 32 of 72 patients, taken either at the time of admission or during the stay of the patients in the hospital. The frequency of contamination increased with the duration of the stay of the patients in the hospital as follows: 20 per cent at the time of admission, 71 per cent after 8 to 10-day stay and up to 100 per cent for a duration of stay exceeding 14 days. The germs were mainly localized in the nose-throat region and in the respiratory tract. The results of phage typing suggested a hospital infection in about 50 per cent of the patients. The relationship between infection and infectious disease was discussed with respect to the epidemiologic characteristics of intensive care units. Furthermore, it was attempted to formulate recommendations for interrupting or abolishing the infection chains.
