目的 调查河北医科大学第三医院骨科术后切口感染情况。方法 回顾性分析2 106例骨科术后切口感染患者相关资料。结果 骨科术后切口感染率为6.23%。切口感染病原菌：革兰阴性杆菌占65%,革兰阳性球菌32%,真菌3%。检出率较高的7种病原菌为金黄色葡萄球菌（27.87%）、铜绿假单胞菌（23.84%）、阴沟肠菌（12.25%）、大肠埃希菌（11.30%）、鲍曼不动杆菌（7.74%）、凝固酶阴性葡萄球菌（3.99%）、普通变性杆菌（2.85%）。引起感染的因素为开放性污染伤口、糖尿病、反复使用抗生素及住院时间过长。感染细菌中耐药细菌及比率：耐甲氧西林金黄色葡萄球菌（4.84%）、多重耐药鲍曼不动杆菌（1.19%）、超广谱β-内酰胺酶的细菌和头孢菌素酶（0.94%）。还有1例为泛耐药铜绿假单胞菌。结论 骨科手术后切口感染率较高,部分病原菌耐药性明显。

英文摘要：

Objective To investigate the infection of incision in department of orthopedics of the third affiliated hospital of Hebei medical university. Methods The related data of 2 106 patients with incision infection after operation in department of orthopedics were retrospectively analyzed. Results The wound infection rate was 6.23% after orthopaedics operations. The main pathogens were Gram-negative bacteria （65%）, the next was Gram-postive bacteria（32%）, and the rate of fungus inecftion was 3%. The top 7 pathogens were staphylococcus aureus（27.87%）. pseudomonas aeruginosa （23.87 %）, enterobacter cloacae （ 12.25 %）, escherichia coli （ 11.300%）, baumanii（7.74%）, coagulase negative staphylococcus （3.99%）, and bacillus proteus vulgaris （2.85%）. The causive factors for infecetrion were open infection wound, hyperglycemia, repeated usage of antibiotics, and long hospitalization. There were multi-resistant bacterias such as methicillin-resistant staphylococcus aureus （4.84%）, multiresistant Acinetobacter baumannii （1.19%）, produce ultra broad spectrum beta lactamase coli（0. 94%）, and 1 case of pan-drug- resistant pseudomonas aeruginosa. Conclusion The infection rate of incision infection after operation in department of orthopedics was high, and the drug resistance of some pathogenic bacteria was obviously.
