摘　　要：目的探讨外科手术部位感染的危险因素,为采取有效措施减少手术部位感染提供依据。方法采用病例对照研究的方法对7种外科手术的手术部位感染状况进行监测研究。结果发生外科手术部位感染共24例,手术部位感染率为3.9%,其中Ⅰ类手术感染率为11.9%,Ⅱ类手术感染率为2.8%,Ⅲ类手术感染率为14.3%;颅脑手术手术部位感染率为17.8%,位居第1;感染部位分泌物培养病原菌以革兰阴性杆菌为主。结论手术部位感染危险因素与年龄、性别、手术时间、住院天数、有无植入物、是否引流及麻醉方式有关,其中有无植入物、住院天数、年龄、手术时间这4个因素与医院感染有显著关系。OBJECTIVE To investigate incidence and risk factors of surgical site infection（SSI）,and provide the reference for taking effective measures to reduce incidence of SSI.METHODS A case-control methods was used to study the incidence of surgical site infection of seven surgical operations.RESULTS SSI occurred in 24（3.9%） of 609 patients,of which 11.9% were typeⅠ,2.8% were type Ⅱ and 14.3%were type Ⅲ.The SSI rate of neurosurgery was 17.8%,was highest.Gram-negative bacilli is the most common in the secretion culture of the site of infection.CONCLUSIONThe risk factors for surgical site infection are associated with the age,sex,surgical duration,length of stay,implants,drainage and anesthesia.The implants,length of stay,age,surgical duration are significantly related to SSI.
