使用微生物鉴定仪器分析妇产科术后感染切口的病原菌分析

Analysis of Pathogenic Bacteria in Infection Incisions After Gynecological Obstetrics Using Microbiological Identification Instruments

目的:通过使用微生物鉴定仪器研究妇产科术后感染切口病原菌情况。方法:以医院2017年7月~2019年7月收治的79例妇产科术后切口感染产妇为研究对象,在采集产妇的相关标本后,应用珠海迪尔DL-96系统对样本的病原菌进行分析,参照美国CLSI标准转入WHONET软件进行分析。结果:本次研究中,79例产妇共发现细菌38株,其中金黄色葡萄球菌所占比例最多,其次为大肠埃希菌等;从优势菌的耐药性来看金黄色葡萄球菌对环青霉素等药物的耐药性较高,但是对阿米卡星和左氧氟沙星的耐药性较低;大肠埃希菌对头孢曲松、氨苄西林的耐药性较高,对哌拉西林/他唑巴坦的敏感度较高。结论:通过微生物鉴定仪器分析结果证明妇产科术后切口感染的病原菌分布相对特殊,并且优势菌对药物的敏感度存在差异,因此在临床上为了取得满意效果,应该根据实验室分析结果进一步调整治疗方法,这样才能加快产妇康复。

Objective:To study the situation of pathogenic bacteria in incision wounds in gynecology and obstetrics by using microbiological identification instruments.Methods:A total of 79 maternal patients with incisional infections in the gynaecology department were treated in the hospital from July 2017 to July 2019.After collecting relevant specimens from the women,the samples were analyzed by Zhuhai Deere DL-96 system,and transferred to WHONET with reference to the US CLSI standard.Software for analysis.Results:In this study,a total of 38 strains of bacteria were found in 79 cases of pregnant women,of which Staphylococcus aureus accounted for the largest proportion,followed by Escherichia coli,etc.;From the resistance of dominant bacteria,Staphylococcus aureus has high resistance to drugs such as cyclopenicillin,but less resistant to amikacin and levofloxacin;Escherichia coli is more resistant to ceftriaxone and ampicillin,and is resistant to piperacillin/tazobar Tan has a higher sensitivity.Conclusion:The analysis results of microbiological identification instruments prove that the distribution of pathogenic bacteria of incision infection in gynecology and obstetrics is relatively special,and the sensitivity of dominant bacteria to drugs is different.Therefore,in order to obtain satisfactory results in the clinic,it should be further adjusted based on laboratory analysis treatments to speed up maternal recovery.
