894例外科感染致病菌分析

目的　了解外科感染的特点和主要病原菌及耐药性。方法　对临床上有可疑感染的 894例 ,进行细菌培养归类和耐药性分析。结果　 894例中培养阳性者 2 85例 ,占 31.8% ;主要的病原菌依次为铜绿假单胞菌 2 8.7%、金黄色葡萄球 18.6 %、大肠埃希菌 19.4 %、霉菌 15 .4 %。药敏试验 (1)铜绿假单胞菌的耐药性为 :哌拉西林 19% ,头孢他啶为 4 .4 % ,亚胺培南为 1.9% ,庆大霉素 4 8% ,阿米卡星 8.4 % ,环丙沙星 14 %。 (2 )金黄色葡萄球菌 (非MRSA)对青霉素和氨苄西林的耐药率分别为 83%和 19% ;哌拉西林 5 6 % ;头孢唑林 0 .9%、阿米卡星 1.5 % ;对亚胺培南 0 .1% ,对万古霉素为 0。 (3)大肠埃希菌的耐药率为 :氨苄西林 78% ,庆大霉素 2 6 % ,哌拉西林 2 9% ,环丙沙星 4 9% ,头孢他啶为 3.4 % ,亚胺培南 4 % ,阿米卡星 3.4 %。结论　我院外科感染的主要致病菌依次为铜绿假单胞菌、金黄色葡萄球菌、大肠埃希菌、克雷伯菌和霉菌。感染的首要致病菌是铜绿假单胞菌 ,真菌感染在我院的外科感染中也占有突出的位置

Infection analysis of Pathogenic bacteria in Surgery department for 894 Cases

Objective To analtses the infection characteristic of surgical department and the main pathogenic bacteria and their resistances.Methods Eight hundreda and ninety four patients with clinical infection evidences were collected and 285 strains were isolated from them.The resistances of these bacteria were analysed by the method of culture of bacteria.Results It was found that 285 of all 894 cases (31.8%) were positve in culture of bacteria,and the main pathogenic bacteria of the isolated strains were successively P.aeruginosa (28.7%),S. aureus (18.6%),E. coli (9.4%) and fungi (15.4%).P. aeruginosa was resisant to piperacllin (19%),ceftazidine (4.4%),imipenem (1.9%),gentamycin (48%),amikacin (8.4%),and cipirofloxacin (14%),S.aureus was resistant to penicillin (83%),ampicillin (91%),piperacillin (56%),cefazlin (9%),amikacin (1.5%),pmipenm (0.1%),and vancomycin (0%),E.colil was resistant to ampicillin (91%),gentamycin (26%),piperacillin (29%),ciprofloxacin (49%),ceftazidine (3.4%),imipenm (4%),and amikacin (3.4%).Conclusion The main pathogennic bacteria are P.aeruginosa,S.aureus,E.coli and fungi in surgcal infection in propre order.Eungi infection was prominent in surgery department.
