【摘要】 目的了解群体烧/创伤患者医院感染发生情况,并探讨其危险因素。方法对2014年5月12日某院收治的"公交车爆燃事件"共25例住院群体烧/创伤患者的医院感染情况进行监测分析。结果 25例烧/创伤患者,其中发生医院感染7例,10例次,医院感染发病率为28.00%,例次发病率为40.00%;感染部位以创面和下呼吸道为主,分别占60.00%和30.00%。7例医院感染患者共检出病原菌30株,其中革兰阴性(G-)菌16株(53.34%)、革兰阳性(G+)菌13株(43.33%)、真菌1株(3.33%)。烧伤总面积大、吸入性损伤程度高、动静脉插管、泌尿道插管、气管切开、使用呼吸机、外科手术均是烧/创伤患者医院感染的危险因素。结论群体烧/创伤患者医院感染发病率较高,应根据其危险因素制定相应的干预措施,减少医院感染的发生。更多还原

【Abstract】 Objective To understand healthcare-associated infection(HAI)in group burn/trauma patients,and explore its risk factors.Methods HAI occurred among 25 hospitalized patients with group burn/trauma during a bus deflagration event on May 12,2014 were monitored and analyzed.Results Of 25 burn/trauma patients,7 developed 10 times of HAI,incidence and case incidence of HAI were 28.00% and 40.00%respectively;the main infection sites were wound and lower respiratory tract,accounting for 60.00% and 30.00% respectively.30 strains of pathogens were isolated from7 patients with HAI,including 16 strains(53.34%)of gram-negative bacteria,13strains(43.33%)of gram-positive bacteria,and 1 fungus(3.33%).Risk factors for HAI were large burned area,high degree of inhalation injury,arteriovenous catheterization,urinary tract catheterization,tracheotomy,use of ventilator,and surgery.Conclusion Incidence of HAI is high in the group burn/trauma patients,corresponding intervention measures should be formulated according to the risk factors,so as to reduce the occurrence of HAI.更多还原
