新生儿血培养的病原菌分布及耐药分析

Neonatal blood culture the bacterium of cause of disease of distribution and drug resistance analysis

目的了解本院新生儿血培养标本病原菌的分布及耐药情况。方法采用BACT/ALERT 3D全自动血培养仪对新生儿血液标本进行血培养,所有菌株采用法国梅里埃公司的ATB Expression系统进行鉴定及药敏试验。结果 42例病原菌中以革兰阳性球菌为主,占全部的83.3%。表皮葡萄球菌在革兰阳性球菌占首位,革兰阳性球菌均对万古霉素均敏感,对苯唑西林耐药率高;革兰阴性杆菌对碳青霉烯类抗菌药物均敏感。结论新生儿血培养结果为临床医生治疗危重患儿提供了实验依据,对患儿的治疗、抢救有积极的意义。

Objective To understand the hospital neonatal blood culture specimens pathogen distribution and resistance.Methods Bact / Alret 3Dautomated blood culture system of neonatal blood samples for blood culture , all the strains using the ATB Expres- sion system of the French Merieux identification and drug sensitivity.Results 42cases of pathogens in Gram-positive cocci , accounting for 83.3%.Staphylococcus epidermidis accounted for the first Gram-positive cocci , Gram-positive cocci were sensitive to vancomycin , Resistance rate to oxacillin ; Gram-negative bacilli were sensitive to the carbapenem antibiotics.Conclusion neonatal blood culture results for clinical medical treatment in critically ill children to provide an experimental basis , the treatment of chil- dren , the rescue of positive significance.
