| 目的探讨层流洁净手术室术后并发感染的病原菌调查、危险因素及相关防控措施。方法 2016年 7月至 2019年2月在延安大学附属医院层流洁净手术室进行手术治疗的病人 360例纳入本次研究，统计术后并发感染及其病原菌检出情况，并对层流洁净手术室病人感染的危险因素行 logistic分析。结果 360例层流洁净手术室病人术后并发感染 43例，病原菌检出 54株，多数为革兰阳性菌，占 94.44%，其中表皮葡萄球菌、金黄色葡萄球菌比例最高；发生感染者与未发生致病菌者年龄、手术刀使用时间、参观人员及术前住院时间差异无统计学意义(P＞0.05)；与未发生感染者比较，发生感染者手术室级别(普通无菌)、手术室无菌管理(不达标)、手卫生(不达标)、手术中人员流动大所占比例较高，差异有统计学意义(P＜0.05)；经logistic分析，手术室级别、手术室无菌管理、手卫生、手术室人员流动大是术后并发感染的危险因素( OR＝8.873、13.474、1.191、2.053，P＝0.000、0.008、0.002、 0.012)。结论层流洁净手术室术后并发感染中革兰阳性菌所占比例最高。手术室级别、手术室无菌管理不达标、手卫生不达标及术中人员流动大是层流洁净手术室术后并发感染危险因素，应当采取有效防控措施改善预后生存质量。 |

| Objective To investigate the pathogens，risk factors and related prevention and control measures of infection in laminar flow clean operating room.Methods Three hundred and sixty cases of patients who were treated in the laminar flow clean operat? ing room in the Yan’an University Affiliated Hospital from July 2016 to February 2019 were enrolled in the study.The postopera?tive infection and the detection of pathogens were statistically analyzed，and the risk factors of infection in laminar flow clean oper? ating room were analyzed by logistic analysis.Results There were 43 cases of infection in 360 patients with laminar flow clean op? eration.54 pathogens were detected，mainly Gram?positive bacteria，accounting for 94.44%.Among them，the proportion of Staphylo?coccus aureus and Staphylococcus epidermidis was the highest.There was no statistically significant difference in the age of thepathogen?infected patients，the time of scalpel use，the visitor and the preoperative hospital stay(P＞0.05).Compared with the non? infected patients，there was no statistically significant difference in the operating room level(general sterility)，surgical sterile sup? plies management(not up to standard)，hand hygiene(not up to standard)，and the flow of personnel during surgery(the propor? tion was higher)in infected patients(P＜0.05).Logistic analysis showed that the operating room level，operating room aseptic man? agement，hand hygiene，and large staff turnover in the operating room were the risk factors for postoperative infection(OR＝8.873， 13.474，1.191，2.053，P＝0.000，0.008，0.002，0.012).Conclusions The proportion of gram?positive bacteria is the highest in lami? nar flow clean operating rooms.The operation room level，the management of sterile equipment in the surgical room and the hand hy? giene are not up to standard，and the staff turnover of the intraoperative is greater，which are risk factors for the infection of the lam? inar flow clean room.Effective prevention and control measures should be taken to improve the prognostic quality of life of patients. |
