下肢骨折病人内固定术后医院感染危险因素分析

ANALYSIS OF RISK FACTORS FOR NOSOCOMIAL INFECTION IN PATIE- NTS WITH LOWER EXTREMITY FRACTURE AFTER INTERNAL FIXATION

目的 探讨下肢骨折患者行内固定术后发生医院感染的危险因素,为采取预防措施提供依据。方法 回顾分析568例该类患者的临床资料,分析患者的感染类型、感染病原菌分布及感染的危险因素。结果 568例患者中有41例发生医院感染,发生率为7.21%;感染的类型以呼吸道感染、切口感染及泌尿系感染为主;主要病原菌为革兰氏阴性菌(50%)、革兰氏阳性菌(42.11%)及真菌(7.89%)。年龄、住院时间、损伤类型、侵入性操作、糖尿病是该类患者发生医院感染的危险因素(OR=3.250~7.681,P<0.05)。结论 下肢骨折病人行内固定术后,应根据易感危险因素尽早采取干预措施,降低医院感染发生率。

Objective To investigate the risk factors of nosocomial infection in patients with lower extremity fractures after internal fixation, and to provide evidence for preventive measures. Methods The clinical data of 568 patients were analyzed retrospectively. The infection type, distribution of pathogenic bacteria and risk factors of infection were analyzed. Results Among the 568 patients, 41 cases had nosocomial infection, thus the incidence rate was 7.21%. The type of infection was mainly respiratory infection, wound infection and urinary tract infection. The main pathogen was Gram-negative bacteria (50%), Gram Positive bacteria (42.11%) and fungi (7.89%). Age, length of hospital stay, type of injury, invasive procedure, and diabetes were risk factors for nosocomial infection in these patients (OR=3.250-7.681, P <0.05). Conclusion After internal fixation on patients with lower extremity fractures, intervention measures should be taken as early as possible according to the risk factors, so as to reduce the incidence of nosocomial infection.
