摘要
目的探讨重症监护病房（ICU）革兰氏阴性菌院内感染的临床特点：方法收集温州医学院附属第一医院ICU2005年1月～2007年12月ICU院内感染病例217的痰、尿、血、大便、创口分泌物及腹水标本719份进行细菌培养，并分析革兰氏阴性致病菌的种类和耐药性：结果719份送检标本共分离出各种致病菌658株：革兰氏阴性菌372株，占56．53％。其中占前5位的是鲍曼不动杆菌62株（16．67％）、洋葱假单胞菌61株（16．40％）、铜绿假单胞菌58株（15．59％）、嗜麦芽窄食单胞菌41株（11．02％）、肺炎克莱布斯氏杆菌34株（9．14％）．革兰氏阴性菌院内感染部位主要为下呼吸道（79．84％）、血液（6．99％）和泌尿道（4．84％）：结论ICU院内感染的病原菌多为革兰氏阴性菌，且对绝大多数抗菌药物都耐药。感染部位以下呼吸道占绝大多数。
Objective To explore the clinical features of nosocomial Gram-negative bacteria infeetions in intensive care unit. Methods 719 specimens of sputum, urine, blood, feces, secretion from tresis vulnus, and aseites collected from 217 patients with nosocomial infection in the ICU of the First Affiliated Hospital of Wenzhou Medical College underwent bacterial culture. Results Gram-negative bacteria were isolated from 372 of the 719 delivered specimens, including 62 strains of Acinetobaeter baumannii （16.67%）, 61 strains of Pseudomonas cepacia （16.40%）. 58 strains of Pseudomonas aeruginosa （15.5%）, 41 strains of Stenotrophomonas mahophilia （11.02%）, 34 strains of Klebsiella pneumoniae （9.14%）, etc. Low respiratory tract accounted for 79.84% of the infection sites, blood accounted for 6.99%, and urinary tract accounted for 4.84%. Conclusion The main pathogenic bacteria of nnsocomial infection in ICU are Gram-negative, most of which are resistant to most of the antibiotics. The mainly affected sites of these bacteria were low respiratory tract, blood, and urinary tract.
