耳鼻咽喉科住院患者医院感染调查分析

目的了解耳鼻咽喉科住院患者医院感染发生的特点,为进一步控制医院感染提供依据. 方法对耳鼻咽喉科1999～2003年住院患者进行医院感染调查,并对造成医院感染的病原菌进行分析. 结果耳鼻咽喉科住院患者医院感染率为4.19%,手术患者医院感染率明显高于非手术患者,其中喉切除并颈淋巴结清扫术感染率最高,感染部位以手术切口为主;引起医院感染的主要病原体为铜绿假单胞菌、表皮葡萄球菌和大肠埃希菌,对临床常用抗生素均存在一定的耐药性. 结论加强手术管理是耳鼻咽喉科控制医院感染的重点,临床医师避免长期滥用广谱抗生素,根据主要诱发因素采取有效地控制措施.

Nosocomial Infection for Inpatients in Department of Otolaryngology: An Investigational Analysis

OBJECTIVE To investigat e the characteristics of nosocomial infection(NI) in department of otolaryngology,and to provide basis for controlling nosocomial infection. METHODS Investigation of inpatients in de partment of otolaryngology by retrospective sampling studied for nosocomial infe ction was carried out during Jan 1999-Dec 2003,and the pathogenic bacteria lea ding to hospital infection were analyzed. RESULTS The incidence rate of nosocomial infection in otolaryngologic department was 4.19%.NI rate of inpatients who un derwent surgical treatment was higher than that of other inpatients.The rate of infection in cases with laryngectomy and necknode dissections was the highest(6 2.38%).The most frequent site of NI was the surgical site wound(45.54%). The pathogens leading to hospital infection mainly were Staphylococcus epid ermidis,Pseudomonas aeruginosa and Escherichia coli which were 31.63%,22.45%,and 13.27% respectively.and they ha d higher resistance against common antibiotics. CONCLUSIONS More attention should be paid to those patients with operation in controlling hospital infection in d epartment of otolaryngology.Long lasting abusing of broad-spectrum antibiotics should be avoided.We should strengthen surveillance on factors inducing infecti on and adopt effective measures to prevent NI.
