1986—1996年我院烧伤病原菌和细菌耐药性变迁

目的 通过对我院１９８６￣１９９６年烧伤感染病原菌及耐药性的调查，分析烧伤感染病原菌和细菌耐药性变迁。方法 对１９８６年６月￣１９９１年５月，及１９９１年６月￣１９９６年６月两个时期的烧伤病人，分别进行血培养和创面培养细菌检出情况及药敏调查。结果 血培养结果表明微球菌上升至第一位，占２１．６％；金黄色葡萄球菌退居第三位，其中，Ｇ＾＋球菌占５６．５％，Ｇ＾－杆菌占３０．１％。创面培养，绿脓杆菌居首，

The change in bacterial flora and antibiotic resistance of bacteria of burn patients in our hospital during 1986-1996]

OBJECTIVE: In this article we investigated and analyzed the pathogenetic bacteria of burn infection and their drug resistance in recent 5 years from 1991. METHODS: The patients are divided into 2 groups. The 1st group is from June 1986 to May 1991, and the 2nd group is from June 1991 to June 1996. Blood culture and burn wound bacteria culture were done, and bacteria and their drug sensitivity were analyzed. RESULTS: In blood culture, Micrococcus had risen to rank the top (21.6%), while Staphylococcus aureus fell to rank the third. Among these G+ cocci comprised 56.5%, and G- bacilli 30.1%. In burn wound culture, Pseudomonas aeruginosa with rate of 18.1% was still in the 1st place. Enterobacter cloacae was in the 2nd place with the rate of 13.1%. Among these G- bacilli comprised 58.6%, G+ cocci 35.3%. Micrococcus enterobacter cloacae, Pseudomonas maltophilia, fecal Staphylococcus and candida albicans increased remarkably. CONCLUSION: The changes of pathogenetic bacteria of burn infection and bacteria drug resistance have certain relations with the wide usage of broad spectrum antibiotics such as cefazidime and imipenem.
