【摘要】：目的探讨下颌阻生智齿拔除术后医院感染患者的病原学特点及危险因素,为术后感染采取积极的预防措施等方面提供思路。方法选择医院口腔科2014年6月-2016年4月期间收治的847例下颌阻生智齿的患者,均采取下颌阻生智齿拔除术治疗,详细记录患者年龄、性别等一般临床资料,记录其术后感染率的发生情况、感染部位、病原学特点,对引起其发生感染的相关因素进行单因素和多因素Logistic分析。结果在847例下颌阻生智齿拔除术后的患者中,有115例患者感染,感染率为13.6%;发生感染的部位主要分布于创面、口腔黏膜和呼吸道;115例感染患者中共分离出病原菌127株,以革兰阴性菌为主,共101株占79.5%;Logistic多元回归分析结果显示,年龄、手术时长、手术方式、术后出血情况、术前未预防性使用抗菌药物是下颌阻生智齿拔除术后感染的独立相关因素(P0.05)。结论应根据下颌阻生智齿拔除术后医院感染的相关因素进行综合防控,降低感染率。
[Abstract]:Objective to explore the etiological characteristics and risk factors of nosocomial infection after mandibular impacted wisdom tooth extraction. Methods from June 2014 to April 2016, 847 patients with mandibular impacted wisdom teeth were treated with mandibular impacted wisdom tooth extraction. The patients' age, sex and other general clinical data were recorded in detail. The incidence of infection, site of infection and etiological characteristics were recorded. Univariate and multivariate Logistic analysis were carried out to analyze the related factors that caused the infection. Results among 847 patients after mandibular impacted wisdom tooth extraction, 115 patients were infected, the infection rate was 13.60.The site of infection was mainly distributed in wound, oral mucosa and respiratory tract. A total of 127 strains of pathogenic bacteria were isolated from 115 infected patients, of which 101 strains were Gram-negative bacteria (79.5%). Logistic multiple regression analysis showed that age, length of operation, operation mode, postoperative bleeding, preoperative non-prophylactic use of antimicrobial agents were the independent factors of infection after mandibular impacted wisdom tooth extraction (P0.05). Conclusion according to the related factors of nosocomial infection after mandibular impacted wisdom tooth extraction, comprehensive prevention and control should be carried out to reduce the infection rate.
