目的：探讨新生儿脐炎的病原菌类型和药敏情况，从而为临床上抗生素的使用提供依据。方法：选取我院收治的新生儿脐炎患者150例作为研究对象，采集脐分泌物和血液，在微生物室进行病原菌的培养和分离鉴定，进而检测菌种、进行药敏试验。结果：在150份标本中，病原菌共检出134例，占比89．3％。其中以金黄色葡萄球菌检出率最多，共计41例占比30．6％，其次依次为大肠埃希菌（15．0％）、表皮葡萄球菌（12．7％）、肺炎克雷伯菌（11．2％）、溶血葡萄球菌（7．5％）、木糖葡萄球菌（6．0％）、铜绿假单胞菌（4．5％）、粘质沙雷菌（3．7％）。其中，革兰阳性球菌对苯唑青霉素、原始霉素、褐霉素、万古霉素的敏感性较高；革兰阴性杆菌对亚胺硫霉素、头孢甲氧噻吩、丁胺卡那霉素、环丙氟哌酸的敏感性较高。结论：分析并了解新生儿脐炎的病菌类型和药物敏感状况，有利于医师合理使用抗菌药物，从而提高临床疗效。“,”objective:to study the neonatal umbilical infection of pathogenic bacteria types and drug susceptibility,to provide the basis for the clinical use of antibiotics.Methods:select our hospital 150 cases of neonatal umbilical infection patients as the research object,col ecting umbilical discharge and blood,in the cultivation of the pathogen and separate identification of mi-crobial room,then test strains,drug sensitive test.Results:among the 150 specimens,pathogenic bacteria were detected 134 cases,accounting for more than 89.3%.With staphylococcus au-reus detection rate most,a total of 41 cases accounted for 30.6%,the second order for e.coli (15.0%)and the epidermis staphylococcus (12.7%),klebsiel a pneumoniae (11.2%),he-molysis staphylococcus (7.5%),xylose,staphylococcus aureus (6.0%),pseudomonas aeruginosa (4.5%),glue,Mr Charest bacteria (3.7%).Among them,the gram positive coccus of benzyl penicil in,the sensitivity of the original drug,brown secretion,vancomycin is higher;Gram-negative bacil i of imide sulfide toxin,cephalosporins oxygen thiophene,high sensitivity of amikacin ciprofloxacin.Conclusion:analysis and understanding of neonatal omphalitis types of bacteria and drug sensitive conditions,conducive to the rational use of antimicrobial agents,so as to improve clinical curative ef ect.
