| Abstract: | Ninety cases of closed drainage urinary catheterization were studied by daily bacteriologic monitoring with Microstix. In 23 per cent of the patients bacteriuria developed, and 92.6 per cent of all catheter infections occurred within three days. These infections occurred primarily in postsurgical patients, and were probably related to initial contamination during catheter insertion. Only 1 patient had a positive drainage bag urine culture prior to the development of bladder bacteriuria. At our institution poor catheter technique was much more important as a risk factor of nosocomial urinary tract infection than an antiseptic drainage bag system. |
