【摘要】：目的分析心脏手术后医院感染发生现状及高危因素,为感染的预防与控制提供依据。方法选取2014年6月-2016年5月医院的心脏手术患者375例为研究对象,将其术后医院感染率进行统计,分析感染部位、病原菌分布及感染因素。结果共19例患者发生医院感染,感染率为5.07%,以呼吸道感染为主,共10例占52.63%;共检出23株病原菌,以革兰阴性菌为主,共15株占65.22%;logistic回归分析显示,年龄较高、手术时间较长、抗菌药物联用、呼吸机应用时间较长、导尿管留置时间较长、血糖较高及体外循环手术是发生医院感染的独立危险因素(P0.05)。结论心脏手术后医院感染率较高,其中呼吸道感染为主,革兰阴性菌仍是主要病原菌,且其高危因素较多,应给予针对性干预。
[Abstract]:Objective to analyze the present situation and high risk factors of nosocomial infection after cardiac surgery, and to provide evidence for prevention and control of infection. Methods 375 patients undergoing cardiac surgery from June 2014 to May 2016 were selected as the study subjects. The postoperative nosocomial infection rate was counted and the location of infection, distribution of pathogenic bacteria and infection factors were analyzed. Results Nosocomial infection occurred in 19 patients, the infection rate was 5.07, respiratory tract infection was the main infection, 10 patients accounted for 52.63.The results showed that 23 strains of pathogenic bacteria, mainly Gram-negative bacteria, and 15 strains of Gram-negative bacteria accounted for 65.2222 logistic regression analysis showed that the age was higher and the operation time was longer. Combined use of antimicrobial drugs, longer time of ventilator, longer time of catheter indwelling, high blood sugar and cardiopulmonary bypass were independent risk factors of nosocomial infection (P0.05). Conclusion the nosocomial infection rate is higher after cardiac surgery, among which respiratory tract infection is the main infection, Gram-negative bacteria is still the main pathogen, and its high risk factors are many, should be targeted intervention.
