手外伤伤口感染细菌分布及耐药性分析

目的：了解引起手外伤伤口感染的常见分离菌及耐药情况。方法：采用纸片扩散（KB）法对分离出的病原菌做药敏试验。结果：298株细菌中G-杆菌占62.75%,G＋球菌占33.9%,从药敏结果发现：G＋球菌中葡萄球菌对青霉素、复方新诺明、氨苄西林、阿奇霉素耐药率高达47.17%-94.44%,而肠球菌耐药率多数超过50%;G-杆菌中铜绿假单胞菌对氨苄西林、头孢曲松、头孢呋辛钠、耐药率〉50%,不动杆菌耐药率多数〉50%,大肠埃希菌耐药率相对较低。结论：手外伤伤口感染的常见分离菌为铜绿假单胞菌、凝固酶阴性葡萄球菌、洛菲不动杆菌、金黄色葡萄球菌、鲍曼不动杆菌、肠球菌和大肠埃希菌,而且分离出的细菌存在严重耐药。

DISTRIBUTION AND RESISTANCE OF BACTERIAL INFECTION IN TRAMA WOUND OF HAND

Objective： To investigate the bacteria and resistance in trama wound of hand.Methods：Antimicobial susceptibility test was performed clinical isolates by means of Kirby-Bauer（KB） method.Results：In 298 clinical isolates,gram-postive bacilli acounted 62.75%,gram-negative coccued acounts 33.9%.Antimicobial susceptibility test showed： The resistance rate of Staphylococcus accunted from 47.17% to 94.44% to penicillin,SMZ-TMP,ampicillin,azithromycin.The resistance rate of Enterococcus accunted higher than 50% to ampicillin, ceftriaxome, cefuroxime, Cefazolin. The resistance rate of Acinetobacter accunted higher than 50% to most of antibiotics. The resistance rate of Escherichia coli accunted lower than others. Conclusion：Bacteria in trama wound of hand including Pseudomonas aeruginosa CNS,Acinetobacter lwoffii, Staphylococcus aureus, Acinetobacter baumannii, Enterococcus and Escherichia coli had strong resistance to antibiotics.
