目的了解某驻军医院重症监护病房(ICU)金黄色葡萄球菌感染临床分布及其耐药性现状,为制定防控措施和合理选用抗菌药物提供依据。方法通过回顾性调查方法,对某驻军医院ICU病人送检标本检测结果进行调查与分析。我院2011年1月至2013年9月ICU送检标本中分离出的金黄色葡萄球菌(SA)的分布及药敏结果。结果在调查期间从该医院ICU住院病人送检标本中共分离出金黄色葡萄球菌289株,耐甲氧西林菌株(MRSA)占检出总数的89.6%。病人感染金黄色葡萄球菌有71.6%分离自痰标本,其次是分泌物和尿液标本。临床分离的金黄色葡萄球菌对多种抗菌药物呈普遍耐药,但未分离出耐万古霉素菌株。结论该医院ICU住院病人中检出的金黄色葡萄球菌主要是MRSA菌株,应加强ICU病人送检标本多重耐药菌监测。
Objective To understand the clinical distribution and drug resistance status of Staphylococcus aureus in intensive care unit (ICU) in a military hospital and provide the basis for developing prevention and control measures and rational use of antimicrobial agents. Methods The retrospective investigation method was used to investigate and analyze the test results of ICU patients in a garrison hospital. Our hospital from January 2011 to September 2013 ICU test specimens isolated from Staphylococcus aureus (SA) distribution and drug susceptibility results. Results During the investigation, 289 Staphylococcus aureus isolates were isolated from the inpatients of ICU in the hospital. The methicillin-resistant strains (MRSA) accounted for 89.6% of the total number. 71.6% of patients infected with Staphylococcus aureus were isolated from sputum samples, followed by secretions and urine samples. Staphylococcus aureus isolates were generally resistant to various antimicrobial agents, but vancomycin resistant isolates were not isolated. Conclusions Staphylococcus aureus detected in inpatients in ICU of this hospital is mainly MRSA strains, and multi-drug resistant bacteria in ICU patients should be monitored.
