【摘要】：目的评估普通外科手术部位感染(SSI)的影响因素,提高目标监测的质量,为降低SSI发生率提供临床理论依据。方法依据医院感染监测规范于2015年1月1日至12月31日对普通外科手术部位感染进行目标性检测。监测期间共实施手术920例。采取SPSS19.0软件对相关数据进行统计学分析。结果 SSI综合发生率为4.35%;随着手术危险指数的增加,手术部位感染率升高。分离出病原菌17株,其中大肠埃希菌数量最多为11株。择期手术SSI发生率为2.40%,急诊手术SSI发生率为10.85%,差异有统计学意义(χ2=27.997,P0.05)。普通外科以Ⅱ类切口手术为主,Ⅱ类切口手术的SSI发生率为2.27%,Ⅲ类切口手术的SSI发生率为21.90%,Ⅰ类切口手术无SSI发生;手术时间大于3h的SSI发生率为7.27%,≤3h的SSI发生率为3.71%,差异有统计学意义(χ2=4.136,P0.05);切口长度大于或等于10cm的SSI发生率为13.11%,10cm的SSI发生率为1.82%,差异有统计学意义(χ2=48.966,P0.05)。结论 NNIS评分、切口类型、手术类型、手术持续时间等均可能成为SSI的危险因素。
[Abstract]:Objective to evaluate the influencing factors of (SSI) infection in surgical site, improve the quality of target surveillance, and provide a theoretical basis for reducing the incidence of SSI. Methods from January 1 to December 31, 2015, nosocomial infection surveillance was used to detect surgical site infection. A total of 920 patients underwent surgery during the monitoring period. Adopt SPSS19.0 software to carry on statistical analysis to the related data. Results the overall incidence of SSI was 4.35, and the infection rate of surgical site increased with the increase of surgical risk index. 17 strains of pathogenic bacteria were isolated, of which 11 strains were Escherichia coli. The incidence of SSI in elective operation was 2.40 and that of SSI in emergency operation was 10.85, the difference was statistically significant (蠂 2 27. 997 P 0.05). The incidence of SSI was 2.27 in type 鈪，
