摘　　要：目的探讨外科重症监护病房(SICU)医院感染的特点、危险因素、病原菌分布对预后的影响,为控制感染提供可靠依据。方法回顾性调查2011年7-9月入住SICU>48h患者的病历资料,对其进行分析。结果 SICU医院感染率34.4%,千日感染率为28.61‰,例次感染率45.6%,例次千日感染率为37.92‰;最常见的感染部位是下呼吸道,占59.65%;最常见的病原菌是鲍氏不动杆菌,占36.67%;多药耐药菌的分离率达51.11%;有创机械通气>7d是医院感染独立危险因素。结论 SICU多药耐药菌发生率高,医院感染是多因素作用的结果。OBJECTIVE To determine the epidemiology,risk factors,and outcome of nosocomial infections caused by pathogens in the SICU so as to provide basis for control of the infections.METHODS Retrospective investigation was performed on the clinical data of the patients who enrolled the SICU less than 48 hours from Jul 2011 to Sep 2011.RESULTS The nosocomial infection rate in the SICU was 34.4%,the thousand-day infection rate was 28.61‰,the case-time infection rate was 45.6%,and the case-time thousand infection rate was 37.92 ‰.The lower respiratory tract was the most common infection site,accounting for 59.65%.Acinetobacter baumannii was the most common species of pathogens,accounting for 36.67%.The isolation rate of multidrug-resistant bacteria was 51.11%.The invasive mechanical ventilation with the duration more than 7 days was the independent risk factor for the nosocomial infections.CONCLUSION The incidence of multidrug-resistant bacteria is high in the SICU,and the joint action of the multivariate factors contributes to the incidence of the nosocomial infections.
