Abstract:
Objective Explore the species of pathogenic microorganism and analysis the antibiotic resistance in Emergency department patients in West China Hospital, finding out the evidence for clinical therapy. Methods Select the patients from May 2013 to April 2015 in Emergency department, analyses the species of pathogenic microorganism and the result of drug sensitivity test.Results In the 1 622 cases, there are 1 237 cases of gram-negative bacilli, 324 cases of gram positive coccus, 60 cases of fungus and 1cases of gram-negative coccus, accounted for 76.3%, 19.9%, 3.7%and 0.1%respectively.The top five is E.coli, acinetobacter baumannⅡ, klebsiella pneumoniae, pseudomonas aeruginosa and staphylococcus aureus, accounted for 21.4%, 16.7%, 12.4%, 11.5% and 6.5%; according to the sample species, the detection rate of sputum is highest, accounted for 46.6%, next is blood, urine, secretion; in regard to multiple resistant bacteria, detection rate of ESBL-E.coil, ESBL-KPN , CRAB and MRSA is 62.0% , 26.0%, 80.5% and 26.5%; the detection rate of VREF is 9.4% and does not find Vancomycin resistant enterococcus bacteria. Conclusions The species of pathogenic microorganism in emergency department is rich, especially gram-negative bacilli as E.coli, acinetobacter baumannⅡ, and the drug resistance situation is not optimistic. Emergency department shall communicate with microbiology laboratory timely, pay attention to the situation of the species and the drug resistance result, take rational use of antibiotic according to the results of the analysis of drug resistance.
