摘要
目的分析手术室医院感染的相关危险因素。方法回顾性选取2018 年1 月至2019 年1 月期间在广东省第二中医院术后出现感染的115 例患者作为观察组,并随机选取同期未发生手术室医院感染的85 例作为对照组。比较两组患者在手术室的手卫生及空气质量状况的差异,并分析影响手术室感染的相关危险因素。结果观察组和对照组患者手术前的空气菌落数[(210.42±51.32) cfu/m^3 vs (108.25±43.73) cfu/m^3]、手术后空气菌落数[(877.30±76.51) cfu/m^3 vs (629.81±53.45) cfu/m^3]及手菌落数[(4.56±0.90) cfu/m^3 vs (2.42±0.82) cfu/m^3]比较,观察组明显高于对照组,差异均具有统计学意义(P<0.05);单因素分析结果显示,观察组在术中不同参观人数、不同手术次数、是否应用呼吸机、是否术中输血、手术类型、手术模式、不同手术持续时间、是否合并其他慢性病及不同年龄发生手术室感染的比例比较,差异均具有统计学意义(P<0.05);多因素分析结果显示:手菌落数、术后空气菌落数、应用呼吸机、术中参观人数3 人以上、手术频率1 次以上、污染手术、合并其他慢性病、有术中输血、紧急手术、手术持续2 h以上、年龄大于60岁是手术室感染的独立危险因素(P<0.05)。结论手术室医院感染患者与年龄、手术模式、手术类型、手术持续时间等因素密切相关,临床应分析其感染危险因素,为降低手术室感染率提供参考依据。
Objective To analyze the risk factors of nosocomial infection in operating room. Methods A retrospective study was conducted on 115 patients with nosocomial infection after operation in Guangdong Second Hospital of Traditional Chinese Medicine from January 2018 to January 2019, and 85 patients without nosocomial infection in operation room during the same period were randomly selected as the control group. The differences of hand hygiene and air quality between the two groups were compared, and the related risk factors affecting the infection in the operating room were analyzed. Results The air colony count before operation, air colony count after operation and hand colony count in the observation group were (210.42±51.32) cfu/m^3,(877.30±76.51) cfu/m^3,(4.56±0.90) cfu/m^3, respectively, which were significantly higher than corresponding (108.25±43.73) cfu/m^3,(629.81±53.45) cfu/m^3,(2.42±0.82) cfu/m^3 in the control group (all P<0.05). Univariate analysis showed that the observation group had different number of visitors, different times of operation, whether to use ventilator, whether to transfuse blood during operation, type of operation, mode of operation, different duration of operation, whether to merge other chronic diseases and whether to occur in the operating room at different ages (all P<0.05). The results of multivariate analysis showed that hand colonies, air colonies after operation, ventilator application, more than three visitors during operation, more than one operation frequency, contaminated operation, combined with other chronic diseases, intraoperative blood transfusion, emergency operation and operation duration over 2 h and over 60 years old were independent risk factors for infection in operating room (all P< 0.05). Conclusion Nosocomial infection in operating room is closely related to age, mode of operation, type of operation and duration of operation, and risk factors of nosocomial infection are analyzed to provide reference for reducing the infection rate in operating room.
