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 investigate the characteristics, risk factors and distribution of pathogenic bacteria in surgical intensive care unit (SICU) hospital, and to provide a reliable basis for infection control. Methods The clinical data of patients admitted to SICU> 48h from July to September of 2011 were retrospectively analyzed and analyzed. Results The infection rate in SICU hospital was 34.4%, the infection rate in one millennium was 28.61 ‰, the infection rate in case-one was 45.6%, and the infection rate in case-one was 37.92 ‰. The most common site of infection was lower respiratory tract, accounting for 59.65%. The most common pathogen Acinetobacter baumannii, accounting for 36.67%; multi-drug resistant bacteria isolation rate of 51.11%; invasive mechanical ventilation> 7d is an independent risk factor for nosocomial infection. Conclusion The incidence of multidrug-resistant SICU is high, and nosocomial infection is the result of multi-factor.
