摘　　要：目的探讨胫腓骨骨折内固定植入术后术区感染的致病菌及危险因素。方法通过医院感染监测和细菌分离鉴定方法,对某医院因胫腓骨骨折行内固定植入的患者术后术区感染及致病菌分布进行调查与分析。结果共调查胫腓骨骨折内固定植入术患者598例,发生术区感染41例,感染发生率为6.86%。从患者术区感染标本中共检出病原菌61株,其中革兰阴性菌和革兰阳性菌分别为34株和27株,构成比分别为55.74%和44.26%。年龄≥60岁、开放性骨折、术后引流不通畅、合并糖尿病及GustiloⅢ型骨折等因素构成胫腓骨骨折内固定植入术后术区感染的危险因素。结论胫腓骨骨折内固定植入术后术区感染的发生率较高,革兰阴性菌为主要致病菌,术区感染的发生与多种因素有关,应采取针对性防控措施。Objective To explore the pathogens and risk factors of operative area infection in internal fixation implantation after tibiofibular fracture.Methods Through hospital infection monitoring and bacterial isolation and identification methods,the operative area infection and pathogen distribution in patients with tibiofibular fractures who underwent internal fixation implantation in a certain hospital were investigated and analyzed.Results A total of 598 patients with tibiofibular fractures who underwent internal fixation implantation were investigated,and there were 41 cases of operative area infections,with an infection rate of 6.86%.61 strains of pathogenic bacteria were detected in the samples from operative area infection of patients,of which 34 strains were Gram negative and 27 strains were Gram positive,with a composition ratio of 55.74%and 44.26%,respectively.Age 60 years old,open fracture,poor postoperative drainage,diabetes comorbidity and GustiloⅢfracture were the risk factors for operative area infection in internal fixation implantation after tibiofibular fracture.Conclusion The incidence of operative area infection in internal fixation implantation after tibiofibular fracture is relatively high,with Gram negative bacteria as the main pathogenic bacteria.The occurrence of operative area infection is related to multiple factors,and targeted prevention and control measures should be taken.
