为确定病人入院时其口咽部和(或)直肠内携带绿脓杆菌的发生率,以及入院后此菌在其体内生长繁殖的危险性,作者对连续入院的186例次(180例)病人,分别在入院时,入院1周后和(或)出院时取其直肠和咽部拭子做绿脓杆菌培养。结果发现42例(22.6%)病人入院时培养阳性。20例(10.8%)病人在住院期间感染上绿脓杆菌。入院时从重病房和外科病房的病人体内培养出菌落次数是内科病房的2倍.直肠内细菌培养阳性率明显高于口咽部阳性率(p<
In order to determine the incidence of Pseudomonas aeruginosa in the oropharynx and / or rectum of a patient admitted to hospital and the risk of growth and reproduction of this bacterium in the body after admission, 186 consecutive patients (180 patients) , Respectively, at admission, 1 week after admission and (or) discharged from the rectal and pharyngeal swab Pseudomonas aeruginosa culture. As a result, 42 (22.6%) patients were found to be positive on admission. Twenty patients (10.8%) were infected with Pseudomonas aeruginosa during hospitalization. The number of colonies cultured in intensive care units and surgical ward patients at admission was twice that of the medical ward, and the positive rate of bacterial cultures in the rectum was significantly higher than that in oropharyngeal tissues (p <
