Abstract:

Objective To investigate the kinds and antibiotic susceptibility of isolates in intensive care unit(ICU)of Shanghai Children's Medical Center. Methods VITEK 2 automatic microbial analysis system was used to identify isolates, and antibiotic susceptibility was determined by E-test,Kirby-Bauer(K-B) method and automatic systems. The data were analyzed by WHONET 5.6 software,according to the document of the Clinical and Laboratory Standards Institute (CLSI)2014. Results A total of 5133 non-duplicate isolates were collected in ICU from January 2012 to December 2014. The isolates were mainly isolated from respiratory tract samples (66.8%),blood(15.2%) and urine(11.8%). The primary microorganisms were Klebsiella pneumoniae(16.9%),coagulase-negative Staphylococcus(15.0%),Escherichia coli(14.5%),Acinetobacter baumannii (12.7%)and Staphylococcus aureus(10.1%). The primary microorganisms of multidrug-resistant isolate was extended-spectrum beta-lactamases-producingEnterobacteriaceae(61.0%),and carbapenem-resistant Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae had an increasing tendency. Conclusions The drug resistance of isolates is high in ICU,which should be paid more attention.
