ABSTRACT
OBJECTIVE To explore the effect of smearing catheter surface with chloramphenicol for preventing catheter -associated urinary tract infections. METHODS Totally 100 cases of preoperative patients needed for indwelling urethral catheters were randomly grouped, 50 of 100 cases as test group, and the others 50 cases as the control group. Catheters after smearing surface with chloramphenicol were inserted using aseptic technique in the test group, urinary catheters without using chloramphenicol were inserted in the control group according to routine aseptic technique protocol, and then regularly taken out urinary specimen from two groups respectively for microbial culture. RESULTS The observation showed bacterial growth positive rate was 30%, and 66.7%, respectively in the control group, but positive rate was 6.7%, and 30%, respectively in the test group after the seventh day and the tenth day. There was a statistic significant difference (P
