【摘要】 目的分析四肢骨折以及人工关节置换手术住院患者术后发生医院感染的相关危险因素。方法选取2016年1月至2019年1月医院骨科收治的800例四肢骨折以及进行人工关节置换手术住院患者作为研究对象,患者术后均持续随访调查1年。依据医院感染事件发生情况将研究对象分为感染组(n=28)与非感染组(n=772)。总结感染组患者的感染特点,分析患者发生医院感染的相关危险因素。结果单因素分析结果显示,两组的年龄、术前住院天数、手术治疗部位以及出血量比较,差异有统计学意义(P<0.05);多因素Logistic回归分析结果显示,年龄、术前住院天数以及出血量是术后院感事件发生的危险因素(P<0.05)。结论高龄、术前住院天数较长以及术中大量出血是四肢骨折以及进行人工关节置换手术住院患者受术后感染发生的危险因素,针对存在此类因素患者应加强围术期院感事件预防措施,以降低院感事件发生率。更多还原

【Abstract】 Objective To analyze the related risk factors of nosocomial infection in hospitalized patients with limb fractures and artificial joint replacement.Methods From January 2016 to January 2019, 800 hospitalized patients with limb fractures and artificial joint replacement were selected as the research objects.All patients were followed up for 1 year.The objects were divided into infected group(n=28) and non-infected group(n=772) according to the occurrence of nosocomial infection events.The infection characteristics of patients in the infection group were summarized, and the risk factors of nosocomial infection were analyzed.Results Univariate analysis showed that there were significant differences in age,preoperative hospital stay, surgical site and blood loss volume between the two groups(P <0.05); multivariate Logistic regression analysis showed that age, preoperative hospital stay and blood loss volume were the risk factors of postoperative nosocomial infection events(P<0.05).Conclusion The risk factors of postoperative infection in hospitalized patients with limb fracture and artificial joint replacement are old age, long preoperative hospital stay and massive intraoperative bleeding.In order to reduce the incidence of nosocomial infection events, preventive measures should be strengthened for patients with such factors.更多还原
