Risk factors of the surgical site infection with type I incision and its infection management

目的探讨影响Ⅰ类手术切口感染的相关因素及预防对策。方法对深圳市第二人民医院2005年1月至2011年12月收治的40788例Ⅰ类手术切口患者进行调查,分析感染的相关因素。结果Ⅰ类手术切口感染率为0.451%(184/40788)。其中男性、老年患者、合并糖尿病、有侵入性操作、手术时间较长、住院时间≥20d及既往有手术史是术后切口感染发生的危险因素(P<0.05)。结论完善术前准备,缩短手术时间,术后合理的营养支持等措施能降低切口感染发生率。

Objective To investigate critical factors of all surgical site infection cases with type Ⅰ incision, provide resolution for each case in order to reduce incident rate of infection in hospital. Method 184 cases of surgical site infection were encountered over 40 788 patients with the type Ⅰ incision in our hospital over the period from June 2005 to June 2011. After sample classifications according to patient＇s sexual/age/diabetes status,operation time and operation invasiveness,χ^2 test was used to indicate statistical significant of each classification. Results The incidence rate of the surgical site infection with type Ⅰ incision was about 0.451% （184/40 788）. Aged male patient with diabetes and suffered long operation time has significant high risk in encountering the surgical site infection （P〈0.05）. Conclusion Refining the process of surgery preparation, shortening operation time, and refining the process of nutritional support after operation are main derived solutions in order to reduce the incidence rate of infection with type Ⅰ incision.
