摘　　要：目的探讨和分析重症肺炎患儿病原菌分布特点及抗菌药物耐药趋势。方法选择2014年1月-2016年12月期间医院收治的218例重症肺炎患儿作为临床研究对象,并分别对重症肺炎患儿的病原菌分布特点及抗菌药物耐药趋势进行统计分析。结果 218例重症肺炎患儿中共检出病原菌281株,以革兰阴性菌为主,共147株占52.31%;以痰液检出为主,共208株占74.02%;主要革兰阴性菌对阿米卡星、亚胺培南、头孢哌酮/舒巴坦、美罗培南均表现出较高的耐药性,耐药率均>80.00%,对头孢唑林和头孢噻肟则均表现出较低的耐药性,耐药率均<25.00%。结论重症肺炎患儿病原菌分布以革兰阴性菌为主,治疗过程中应根据病原菌的分布特点及耐药趋势科学合理选择抗菌药物。OBJECTIVE To probe into and analyze distribution characteristics and drug resistance trend of pathogens in children with severe pneumonia.METHODS A total of 218 children with severe pneumonia from Jan.2014 to Dec.2016 were selected as the clinical subjects.The distribution characteristics and drug resistance trend of pathogens in children with severe pneumonia were statistically analyzed.RESULTS There were 281 pathogens detected from 218 children with severe pneumonia,which were mainly 147 strains of gram-negative bacteria,accounting for 52.31%.The main source of pathogens was sputum,which were 208 strains,accounting for 74.02%.The major gram-negative bacteria showed high resistance to amikacin,imipenem,cefoperazone/sulbactam and meropenem,and the resistant rates were all more than 80%,while had low resistance to cefazolin and cefotaxime,with the resistant rates lower than 25%.CONCLUSION Pathogen distribution of children with severe pneumonia is mainly gram-negative bacteria.In the course of treatment,we should scientifically and rationally select antibiotics based on the distribution of pathogens and drug resistance trend.
