脑卒中气管切开术后下呼吸道感染的致病菌分析及临床用药的探讨

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。

A study on the analysis of pathogens in lower respiratory tract infections in stroke patients after tracheotomy and the effects of sensitive antibiotics

Objective To study the pathogens in lower respiratory tract infections in stroke patients after tracheotomy and to evaluate the effects of sensitive antibiotics.Methods Using retospective studies to analyze sputum bacteria culture,drug sensitive tests and effects of sensitive antibiotics in 45 stroke patients after tracheotomy.Results Incidence rate of lower respirstory infections in stoke patients after tracheotomy was 82.5%.Seventy-one strains of pathogenic bacteria were found,63.4% of them were gram negative(G-),31% of them were gram positive,5.6% of them were epiphyte.The efficiency of sensitive antibiotics to control infections was 90%.Conclusions The infection of lower respiratory tract is constant in stroke patients after tracheotomy.The gram negative bacteria are main pathogens.It is suggested to select sensitive antibiotics based on drug sensitive test and characteristics of pathogen,which can control infection effectively.
