目的 调查心脏手术患者医院内感染的致病菌分布及其耐药性.方法 分析2007年1月至2012年12月北京安贞医院心脏手术后发生医院内感染患者各种标本所分离的致病菌株,采用VITEK-Jr全自动细菌鉴定及药敏分析系统鉴定细菌类别,纸片扩散(K-B)法进行药敏试验,应用WHONET5.4软件进行数据分析.结果 共分离致病菌697株,其中革兰阴性杆菌395株(56.7%),革兰阳性球菌239株(34.3%),真菌63株(9.0%);呼吸道感染421例(60.4%),血液感染185例(26.5%),其他部位感染91例(13.1%);主要致病菌中革兰阴性菌为不动杆菌124株(17.8%)、铜绿假单胞菌85株(12.2%)、肺炎克雷伯菌50株(7.2%),革兰阳性球菌为表皮葡萄球菌75株(10.8%)和金黄色葡萄球菌39株(5.6%),真菌为白色假丝酵母43株(6.2%);不动杆菌呈现多重耐药,而铜绿假单胞菌耐药性有降低趋势,其他革兰阴性杆菌耐药性无明显变化;碳青霉烯类抗生素、头孢哌酮/舒巴坦及氧哌嗪青霉素/他唑巴坦对非发酵革兰阴性杆菌保持相对较高的抗菌活性.耐甲氧西林的金黄色葡萄球菌和凝固酶阴性葡萄球菌分别为82.9%和95.9%,未发现耐万古霉素的葡萄球菌.结论 非发酵革兰阴性杆菌及葡萄球菌属是北京安贞医院心脏手术后患者医院内感染的重要病原菌,且耐药性突出.
目的 調查心髒手術患者醫院內感染的緻病菌分佈及其耐藥性.方法 分析2007年1月至2012年12月北京安貞醫院心髒手術後髮生醫院內感染患者各種標本所分離的緻病菌株,採用VITEK-Jr全自動細菌鑒定及藥敏分析繫統鑒定細菌類彆,紙片擴散(K-B)法進行藥敏試驗,應用WHONET5.4軟件進行數據分析.結果 共分離緻病菌697株,其中革蘭陰性桿菌395株(56.7%),革蘭暘性毬菌239株(34.3%),真菌63株(9.0%);呼吸道感染421例(60.4%),血液感染185例(26.5%),其他部位感染91例(13.1%);主要緻病菌中革蘭陰性菌為不動桿菌124株(17.8%)、銅綠假單胞菌85株(12.2%)、肺炎剋雷伯菌50株(7.2%),革蘭暘性毬菌為錶皮葡萄毬菌75株(10.8%)和金黃色葡萄毬菌39株(5.6%),真菌為白色假絲酵母43株(6.2%);不動桿菌呈現多重耐藥,而銅綠假單胞菌耐藥性有降低趨勢,其他革蘭陰性桿菌耐藥性無明顯變化;碳青黴烯類抗生素、頭孢哌酮/舒巴坦及氧哌嗪青黴素/他唑巴坦對非髮酵革蘭陰性桿菌保持相對較高的抗菌活性.耐甲氧西林的金黃色葡萄毬菌和凝固酶陰性葡萄毬菌分彆為82.9%和95.9%,未髮現耐萬古黴素的葡萄毬菌.結論 非髮酵革蘭陰性桿菌及葡萄毬菌屬是北京安貞醫院心髒手術後患者醫院內感染的重要病原菌,且耐藥性突齣.

Objective To investigate the clinical distribution and antibiotics resistance of nosocomial infection caused pathogenic bacteria in patients after cardiac surgery.Methods Clinical data from 612 patients after cardiac surgery under microbiologically documented nosocomial infection was retrospectively analyzed from January 2007 to December 2012.Identification on related bacterial was performed in an automatic ATB Expression system while antimicrobial susceptibility was tested by Kirby-Bauer method.Results were analyzed by WHONET5.4.Results There were 697 strains of clinical pathogenic bacilli isolates identified and 421 (60.4%) of them were isolated from sputum while 185 (26.5%) were from blood.Acinetobacter spp.(124 strains,17.8%),Pseudomonas aeruginosa (85 strains,12.2%) and Klebsiella pneumoniae (50 strains,7.2%) were the predominant Gramnegative bacilli while S.epidermidis (75 strains,10.8%) was the predominant Gram-positive cocci.The predominant eumycete was Candida albicaas (43 strains,6.2%).Results from the susceptibility test showed that carbopenems,cefoperazone/sulbactam and piperacillin/tazobactam were the most active antibiotics.The detection of meticillin-resistant Staphylococcus (MRS) were 82.9% in S aureus and 95.9% in coagulase negative Staphylococcus.There was no Staphylococcus strains resistant to vancomycin found.Conclusion Non-fermenting Gram-negative bacilli and Staphylococcus appeared the important pathogens in patients after cardiac surgery.Drug resistance to antibiotics was quite common.Prevention on nosocomial infection and rational use of antibiotics remained very important in reducing the amount of drug resistant strains.
