目的研究脑卒中气管切开术后患者下呼吸道感染的致病菌特点和敏感抗生素疗效。方法采用回顾性研究方法对本院2000～2006年45例脑卒中气管切开术后患者的下呼吸道感染的致病菌特点、药敏结果和抗生素疗效等临床资料进行分析。结果45例脑卒中气管切开术后患者的痰液标本致病菌检出率为82.5%,检出致病菌71株,63.4%为G-菌,31%为G+菌,约5.6%标本检出真菌;根据药敏结果选用敏感抗生素治疗后有效率达90%。结论脑卒中气管切开术后下呼吸道感染较常见,其中以G-菌感染为主,应根据菌种特点及药敏结果选用敏感抗生素治疗,可取得较好疗效。
Objective To study the characteristics of pathogenic bacteria in lower respiratory tract infection and the effect of sensitive antibiotics in stroke patients after tracheotomy. Methods A retrospective study was conducted to analyze the pathogenic bacteria, antimicrobial susceptibility and antibiotic efficacy of 45 cases of lower respiratory tract infection after tracheotomy in our hospital from 2000 to 2006. Results The detection rate of pathogens in sputum specimens was 82.5% in 45 cases of stroke patients after tracheotomy, 71 of which were pathogenic bacteria, 63.4% were G-bacteria, 31% were G + bacteria and 5.6% Detection of fungi; selection based on susceptibility results of sensitive antibiotics, the effective rate of 90%. Conclusions Lower respiratory tract infection after tracheotomy is more common in patients with stroke. Among them, G - bacteria infection is the main cause of infection. Sensitive antibiotics should be selected according to the characteristics of the strain and drug susceptibility results, and good curative effect can be obtained.
