[摘要] 目的 了解锦州市中心医院铜绿假单胞菌的临床分布及耐药情况,为临床治疗铜绿假单胞菌感染提供参考依据。 方法 本院2014年1月1日~2015年12月15日应用VITEK-2鉴定系统对分离出的铜绿假单胞菌进行细菌鉴定和药敏分析,采用WHONET 5.6软件对药敏结果进行统计分析。 结果 共分离出铜绿假单胞菌325株,主要标本来源为痰液,共检出236株,占72.6%,其次是尿液34株(10.5%)。主要分布科室为呼吸内科,检出119株,占36.6%以及重症监护室,检出58株,占17.8%,其次是神经内科34株(10.5%)。主要抗菌药物的药敏情况为对阿米卡星的敏感率为77.1%,对头孢曲松、复方新诺明的敏感率均<10%,对多种抗菌药物均有不同程度的耐药。 结论 本院临床分离的铜绿假单胞菌主要来源于痰液标本,多分布于呼吸内科和重症监护室,其中对阿米卡星的敏感率最高。

[Abstract] Objective To understand the clinical distribution and drug resistance of Pseudomonas aeruginosa in Jinzhou Central Hospital,and to provide reference basis for clinical treatment of Pseudomonas aeruginosa infection. Methods January 1,2014 to December 15,2015,Pseudomonas aeruginosa isolated form our hospital was given bacterial identification and drug sensitivity analysis using VITEK-2 identification system,and the drug sensitivity result was statistically analyzed by WHONET 5.6 software. Results 325 strains of Pseudomonas aeruginosa were isolated,the main source of sputum sample (236 strains),and it accounted for 72.6%,followed by the urine of 34 strains (10.5%).The main distribution department was department of respiratory internal medicine,119 strains (36.6%) were detected and intensive care unit,the detection of 58 strains (17.8%),followed by the department of nerve internal medicine [34 strains (10.5%)].Main antibacterial drug susceptibility was sensitive rate to amikacin was 77.1%,susceptibility rate to ceftriaxone and trimethoprim sulfamethoxazole were lower than 10%,to a variety of antibacterial drugs showed different degree of resistance. Conclusion Clinical isolated Pseudomonas aeruginosa mainly from sputum sample,and it distributes mainly in the department of respiratory internal medicine and intensive care unit,which is the highest sensitivity of amikacin.

铜绿假单胞菌(Pseudomonas aeruginosa,PAE)是一种非发酵革兰氏阴性杆菌,是专性需氧菌,是一种常见的条件致病菌,广泛存在于自然界如土壤、水源中,也存在于人类的皮肤、肠道、呼吸道中。当机体抵抗力下降或进行侵入性治疗如导尿、气管插管、呼吸机等,容易引起化脓性的炎症以及全身感染[1-2]。由于PAE对抗生素的敏感率低,耐药率高,现已经成为医院感染的主要致病菌[3-4]。多年来的临床经验表明,单一的抗菌药物对大多数革兰氏阴性杆菌尤其是PAE的治疗效果相当不理想,用药不久就会出现耐药性导致治疗失败。PAE的高耐药性给临床医生的治疗带来了极大的困难,而多重耐药的PAE以及泛耐药的PAE给临床抗感染治疗更是带来了巨大的挑战[5]。为了能及时掌握PAE的临床分布及耐药情况,更好地指导临床合理用药,本研究对本院临床分离的PAE进行耐药性分析,现报道如下。……
