目的 探讨新生儿败血症病原体构成特点、影响因素及其抗菌谱 .方法 对 185例经血培养证实的新生儿败血症病原学作回顾性分析 .结果 185例新生儿败血症的病原菌以葡萄球菌为最多 ,机会菌、大肠埃希菌次之 ,其他不太多见的还有链球菌、绿脓假单胞菌 ;其病原体构成与胎龄、生活方式、原发感染病灶密切相关 ;而其药物敏感试验示头孢唑啉、先锋必等为首选抗菌素 .结论 新生儿败血症病原学特点的分析 ,对指导临床诊治有重要价值 .
Objective To investigate the characteristics, influencing factors and antibacterial spectrum of pathogens in neonatal septicemia.Methods 185 eases of neonatal septicemia confirmed by blood culture were retrospectively analyzed.Results Among the 185 neonates with sepsis, the most common pathogens were staphylococci, , Followed by Escherichia coli, and other less common streptococci, Pseudomonas aeruginosa; its pathogen composition and gestational age, lifestyle, primary infection lesions are closely related; and its drug sensitivity test showed cephalosporin Oxazoline, pioneer must be the first choice of antibiotics.Conclusion The analysis of etiological characteristics of neonatal septicemia has important value in guiding the clinical diagnosis and treatment.
