摘　　要：目的调查分析成都市医院手术部位感染的流行病学特征,为进一步研究手术部位感染相关危险因素及干预措施提供依据。方法对成都市10所二甲及以上医院术后住院患者进行24 h现患率调查,分析手术部位感染的危险因素与分布,明确主要病原菌和围手术期用药情况。结果共调查1088例外科术后患者,手术1107例次,发生手术部位感染25例、26例次,手术部位感染率2.3%、例次感染率2.35%;26例次手术部位感染中,表浅切口感染占76.92%,深部切口感染占19.23%,器官/腔隙感染占3.85%;手术部位感染与切口、手术类型、术前感染情况密切相关(P<0.01);手术部位感染主要集中在泌尿外科、烧伤科、骨科和普外科,肠杆菌科是主要病原菌,围手术期抗菌药物使用不规范,Ⅰ类切口手术前使用率为58.50%,术后使用率>99.34%。结论初步揭示了该地区手术部位感染发生的一般规律和存在的问题,为预防和控制手术部位感染提供了参考依据。OBJECTIVE To explore the epidemiologic characters of surgical site infection（SSI） in the hospitals in Chengdu, to provide reference for further research on the risk factors and intervening measures related to SSI. METHODS The risk factors, distribution, major pathogens, and the use of antimicrobials related to SSI were studied by means of 24h prevalence survey on all postoperative inpatients in 10 Grade ⅡClass A Hospitals. RESULTS 1107 operative cases and 1088 surgical patients were investigated and the results showed that 25 patients developed 26 cases of SSI. SSI rate was 2.3%, case infection rate was 2. 35%. Among 26 cases of SSI, superficial incision infection accounted for 76. 92%, 19. 23% deep incision SSIs, and 3. 85% organ/space SSIs. SSI was closely related to the surgical wound classification, urgent or planned surgery, and preoperative infection （P〈0.01）, SSI distributed mostly in Department of Urinary Surgery, Burns, orthopaedics and general surgery, Enterobacteriaceae was the main pathogen; The perio-operative using of antimicrobials was not up to the standard. The using rate of antimicrobials was 58. 50% before operation and above 99. 34% after operation among the patients with surgical wound Class I. CONCLUSIONS This survey preliminarily reveals the general rules and existing problems of the outbreak of SSI, which provide references for the prevention and control on SSI.
