【摘要】：目的探讨我院呼吸科重症监护病房(RICU)患者发生医院感染的主要病原菌的分布及耐药性,为临床合理用药提供依据。方法回顾性分析在我院RICU住院治疗的发生医院感染的186例患者的病原菌构成比、分布特点及药敏试验等情况。结果共分离出483株病原菌,其中革兰阴性菌占74.53%,依次为铜绿假单胞菌、鲍曼不动杆、大肠埃希菌、嗜麦芽寡养单胞菌等;革兰阳性球菌占16.15%,以金黄色葡萄球菌为主;真菌占9.32%,以白色念珠菌为主。感染部位依次为肺部感染(52.07%)、尿路感染(21.20%)、导尿管相关感染(15.21%)。铜绿假单胞菌、鲍曼不动杆菌和大肠埃希菌对阿米卡星的耐药率较低,但鲍曼不动杆菌耐药情况严重。结论肺部感染是RICU患者医院感染的主要感染类型,革兰阴性杆菌是主要病原菌,且鲍曼不动杆菌呈多重耐药。
[Abstract]:Objective to investigate the distribution and drug resistance of main pathogens of nosocomial infection in respiratory intensive care unit (ICU) of our hospital.Methods the composition ratio, distribution and drug sensitivity test of nosocomial infection were analyzed retrospectively in 186 patients with nosocomial infection treated in our hospital with RICU.Results 483 strains of pathogenic bacteria were isolated, of which 74.53 were Gram-negative bacteria, followed by Pseudomonas aeruginosa, Bowman immobility, Escherichia coli, Maltophilia oligotrophomonas, and Gram-positive coccus accounted for 16.15, mainly Staphylococcus aureus.Fungi accounted for 9.32, mainly Candida albicans.The infection sites were lung infection (52.07), urinary tract infection (21.20) and urinary catheter infection (15.21).Pseudomonas aeruginosa, Acinetobacter baumannii and Escherichia coli showed low resistance to amikacin, but Acinetobacter baumannii showed severe drug resistance.Conclusion Pulmonary infection is the main type of nosocomial infection in patients with RICU, Gram-negative bacillus is the main pathogen, and Acinetobacter baumannii is multidrug resistant.
