恶性肠道肿瘤手术患者医院感染危险因素调查分析

Risk factors of nosocomial infection in patients with malignant intestinal tumor

目的探讨恶性肠道肿瘤手术患者医院感染的危险因素,加强医院感染的防治。方法采用前瞻性的调查方法对医院2008-2009年350例恶性肠道肿瘤手术患者的医院感染进行分析,医院感染相关的危险因素进行卡方检验。结果发生感染51例,感染率为14.57%,以腹盆腔感染最多见,病原菌以革兰阴性杆菌为主,占62.27%;感染因素与住院天数、年龄、基础疾病个数、引流管个数及引流时间、是否合并肠梗阻和预防性抗菌药物等有关,差异有统计学意义(P<0.05)。结论为了预防医院感染的发生,应针对危险因素采取相应的预防控制措施。

OBJECTIVE To investigate the risk factors of nosocomial infection for the malignant intestinal tumors as well as its clinical control measures.METHODS A total of 350 patients with malignant intestinal tumors from 2008 to 2009 were enrolled in this research.A prospective survey was used for the nosocomial infection and the risk factors were analyzed by chi-square test.RESULTS Nosocomial infection happened in 51 cases（14.57%）,the common sites of infection was abdominopelvic cavity,the common pathogen was Gram-negative bacteria（62.27%）.The infection risk factors were related to the patient′s ages,the days in hospital,numbers of basis diseases,intestinal obstruction,prophylactic antibiotics,numbers of drainage pipes and drainage time,and so on.CONCLUSION Prophylactic control measures should be taken according to the risk factors in order to prevent the nosocomial infection.
