发布时间：2018-08-25 19:10
【摘要】：目的了解医院老年患者感染耐甲氧西林金黄色葡萄球菌的耐药性及分布特点,评估医院感染控制结果,为临床合理用药提供依据。方法收集2013年-2015年使用MicroScan-autoSCAN4半自动细菌鉴定仪鉴定出281株耐甲氧西林金黄色葡萄球菌(MRSA)的药敏结果和临床资料,采用WHONET 5.6软件对统计结果进行分析。结果 MRSA菌株的检出数依次下降,由2013年的104株降至2015年的79株;在所有的送检标本中,痰标本金黄色葡萄球菌检出比最高占44.83%;血液标本中未发现MRSA菌株;药敏结果分析发现MRSA对青霉素G、苯唑西林完全耐药。结论老年患者MRSA检出率较高,集中管理危重患者,合理有效的使用抗菌药物,及时调整用药有利于控制MRSA的感染。
[Abstract]:Objective to investigate the drug resistance and distribution of methicillin-resistant Staphylococcus aureus (MRSA) in elderly hospital patients and to evaluate the results of nosocomial infection control. Methods the drug sensitivity and clinical data of 281 strains of methicillin-resistant Staphylococcus aureus (MRSA) were identified by MicroScan-autoSCAN4 semi-automatic bacterial identification instrument from 2013 to 2015. The statistical results were analyzed by WHONET 5.6 software. Results the number of MRSA strains decreased from 104 strains in 2013 to 79 strains in 2015, the highest detection rate of Staphylococcus aureus in sputum samples was 44.83%, no MRSA strain was found in blood samples. Drug sensitivity analysis showed that MRSA was completely resistant to penicillin G and oxacillin. Conclusion the detection rate of MRSA in elderly patients is high. Centralized management of critically ill patients, rational and effective use of antimicrobial agents and timely adjustment of drug use can help to control the infection of MRSA.
