急诊外科医院感染临床特征分析

Clinical characteristics of nosocomial infection in emergency surgery department

目的探讨急诊外科医院感染临床特征。方法回顾性分析115例急诊外科医院感染患者的临床资料。结果共分离出121株病原菌,革兰阴性菌78株占64.5%、革兰阳性菌37株占30.6%、真菌6株占5.0%;分布最多的细菌为铜绿假单胞菌占21.5%、金黄色葡萄球菌占16.5%、大肠埃希菌占12.4%;标本分布以痰液(68.7%)和手术切口(16.5%)为主;115例医院感染患者接受各种侵入性操作,留置尿管68例为59.1%、留置胃管63例为54.8%、气管插管60例为52.2%、深静脉置管41例为35.7%、胸穿33例为28.7%和腹穿26例为22.6%。结论急诊外科医院感染以革兰阴性菌为主,降低侵入性操作有利于控制医院感染的发生。

OBJECTIVE To explore the clinical characteristics of nosocomial infection in emergency surgery department. METHODS The data of 115 cases with nosocomial infection in emergency surgery department were reviewed. RESULTS A total of 121 strains of pathogens were isolated of which 78 strains were Gram-negative bacteria （64.5%）, 37 Gram-positive bacteria strains （30.6%）, and 6 fungi strains （5.0%）. The three common bacteria were Pseudomonas aeruginosa （21. 5%）, Staphylococcus aureus （16. 5%） and Escherichia coli （12.4%）. The specimens were mainly distributed in sputum（68.7%） and surgical incision （16.5%）. The cases were treated with indwelling catheter （59. 1%）, indwelling gastric tube （ 54. 8%）, endotracheal intuhation （52.2%）, deep venous catheter （35.7%）, chest Thoracentesis （28.7%） and abdomen paracentesis （22.6%）. CONCLUSION The Gram-negative bacteria are the main bacteria in emergency surgery department, and to reduce invasive operation is useful to control the nosocomail infection.
