腹腔脓肿患者感染优势菌及其耐药性的回顾性分析

Pus germicultures and drug sensitivity tests in patients with abdominal abscess:A retrospective analysis

目的了解腹腔脓肿患者感染病原菌的种类及对抗菌药物的耐药性,指导临床合理用药。方法采集腹腔脓肿患者脓液标本做细菌培养及药敏试验,用ATB Expression细菌鉴定仪做菌株鉴定。结果在91例患者标本中,有72例检出细菌,阳性率为79.1%,分离到细菌达26种计87株(其中15例为2种细菌混合感染),其中革兰阴性菌73株(83.9%),革兰阳性菌14株(16.1%);分离菌居前3位是大肠埃希菌、克雷伯菌、阴沟肠杆菌。药敏试验结果显示革兰阴性杆菌对使用较久的药物大部分耐药。结论腹腔脓肿患者感染菌中以革兰阴性杆菌为主,其中以大肠埃希菌占首位;加强患者病原菌的检测和药敏试验,根药敏结果合理使用抗生素。

Objectives To investigate tile distribution of abdominal abscess pathogens and their drug resistance,and to guide clinically selecting reasonable antibiotics.Methods Germieuhures and drug sensitivity tests were conducted for the pus specimens from the 91 patients with abdominal abscess by ATB expression bacteria identifier.Results Pathogens in 72 of the 91 eases were found, with a positive rate of 79.1%, totally 87 strains of bacteria were isolated from clinical samples. Gram-negative bacilli had 73 strains, accounted for 83.9% and Gram-positives had 14 strains, accounted for 16.1%. The first three position were Escherichia eoli,aeruginosa,Enterobacter aerogenes.Conclusion Dominant pathogens in patients with abdominal abscess are intestinal bacilli,with predominance Gram-negative bacilli;more emphasis should be placed on pathogen detectiou and drug sensitivity tests so that effective antibiotics could be selected and resistant bacteria be reduced.
