神经外科医院感染危险因素分析及干预措施

目的探讨神经外科医院感染状况及其危险因素，采取有效干预措施。方法采用回顾性调查方法，对某院神经外科2009年1～12月医院感染状况进行了调查和分析。结果神经外科住院患者1230例，发生医院感染91例，医院感染率7．40％，例次感染率7．97％。感染部位以下呼吸道居首位，构成比为52．04％；病原菌以铜绿假单胞菌为主，占26．3％。基础疾病、免疫力低下、住院时间长、侵入性操作、不合理应用抗生素为医院感染发生的主要危险因素。结论神经外科患者易发生医院感染，针对危险因素采取综合性的防范措施，对预防控制医院感染发生具有重要意义。

Risk factors and interventions of hospital infection in neurosurgery department

Objective To analyze the situation, risk factors of hospital infection and to take effective interventions. Methods The situation of some hospital infection in neurosurgery department from Jan to Dec 2009 was retrospectively ana- lyzed. Results 1230 inpatients in neurosurgery department, of which 91 had hospital infection. The rate of nosocomial infec- tion in neurosurgery department was 7.40% （91 cases） or 7.97% （98 case times）. The infections of lower respiratory tract ranked the first （52. 04 % ）. Pseudomonas aeruginosa was the major infection pathogens （26. 3 % ）. Uderlying diseases, im- munocompromised, prolonged hospitalization, invasive operation, unreasonable application of antibiotic were the major risk factors of hospital infection. Conclusion Hospital infection rate is high in neuresurgery patients and it is important to prevent and control hospital infection by taking comprehensive preventive measures according to the risk factors.
