骨折术后医院感染的危险因素分析与控制

Risk factors and control measures for nosocomial infections in patients undergoing fracture surgery

目的探讨骨折术后患者医院感染的危险因素并分析相应控制对策,为控制医院感染率提供依据。方法回顾性分析2010年1月-2011年12月医院骨折1897例住院患者病历,统计患者姓名、性别、年龄、病史等临床资料以及骨折类型、手术切口类型、感染部位等可能与感染相关的因素。结果调查1897例患者中发现医院感染68例,感染率为3.58%;患者年龄、病史、骨折类型、手术切口类型、侵入性操作、手术时间和住院时间均是可能诱发骨折术后患者医院感染的危险因素(P<0.05);其中骨折类型和侵入性操作对医院感染的影响尤其值得注意,开放性骨折或接受了侵入性操作的患者更易发生医院感染(P<0.01)。结论临床上应积极采取针对性措施,尽量避免或减少骨折术后患者医院感染的发生。

OBJECTIVE To investigate the risk factors and preventive measures for nonsocomial infection in the patients undergoing fracture operation so as to provide basis for control of nosocomial infections. METHODS The patients who underwent fracture operation in the hospital from Jan 2010 to Dec 2011 were selected to investigate the factors such as the name, gender, age, case history, fracture types, surgical wound types, and surgical sites that may relate to the infections. RESULTS Of 1897 patients investigated, the nosocomial infections accured in 68 patierrts with the infection rate of 3. 58%. The age, case history, fracture types, surgical wound types, invasive operation,operation time and hospitalization duration were the risk factors that may induce the nosocomial infections in the patients after the fracture surgery. （P〈0.05）, the high attention should be paid to the fracture type and the invasive operation, the patients who underwent the open fracture surgery and received the invasive operation were more prone to the nosocomial infections （P〈0.01）. CONCLUSION The hospital should adopt the targeted measures to avoid and reduce the incidence of the nosocomial infections.
