目的对神经内科住院患者医院感染发生情况及病原菌流行病学进行调查分析,提出医院感染控制措施。方法调查自2004年9月至2006年9月我院神经内科193例住院患者医院感染发生情况,分析所分离出病原菌的分布及耐药情况。结果医院感染发生率6.87%,其中肺部感染发生率59.65%。分离出的病原菌以革兰阴性菌为主(67.36%),其次为革兰阳性菌(26.94%)和真菌(5.70%)。革兰阴性菌以铜绿假单胞菌居首位,且呈多重耐药。结论神经内科医院感染发生率较其他科高,医院感染病原菌复杂且对抗菌药物呈多重耐药。应合理选用抗菌药物,医护人员要严格无菌技术操作和消毒隔离管理,预防交叉感染。
Objective To investigate the prevalence of nosocomial infections and the epidemiology of pathogenic bacteria in inpatients in neurology department and put forward the control measures of nosocomial infection. Methods The incidence of nosocomial infections in 193 inpatients from September 2004 to September 2006 in our department of neurology was investigated. The distribution and drug resistance of the isolated pathogens were analyzed. Results The incidence of nosocomial infection was 6.87%, of which the incidence of pulmonary infection was 59.65%. Gram-negative bacteria were the main pathogens isolated (67.36%), followed by Gram-positive bacteria (26.94%) and fungi (5.70%). Gram-negative bacteria Pseudomonas aeruginosa ranks first, and was multi-drug resistance. Conclusion The incidence of nosocomial nosocomial infections is higher than that of other departments. The pathogenic bacteria of nosocomial infections is complex and multi-drug resistant to antimicrobial drugs. Antimicrobials should be used rationally, and medical staff should strictly control the operation of aseptic techniques and disinfection and isolation to prevent cross-infection.
