Infection Distribution and Drug Resistance Analysis of Pseudomonas Aeruginosa in Third District Hospital in Shenzhen Area / 现代检验医学杂志

ABSTRACT

Objective To understand the shenzhen longhua new district and the light district three third district hospital pseudomonas aeruginosa infection the clinical distribution and drug resistance,for clinical provides the basis for scientific and medical treatment.Methods Collected 3 176 clinical specimens in three district hospital from June 2013 to November 2014 and they were done bacteria identification with VITEK-32 bacteria identification instrument of French biomerieux.For pseudomonas aeruginosa specimens using the K-B method and trace the broth dilution method (MIC)to do drug sensitive test,and the inspection results were statistically processed.Results 3 176 specimens pseudomonas aeruginosa isolated total separation rate was 51.16% (1 625/3 176),including respiratory sputum specimens was 52.8% (858/1 625),followed by bronchoalveolar lavage and pus,were 20.1% (327/1 625)and 16.7% (271/1 625).Ward,neurosurgery and thoracic sur-geons are mainly distributed in the ICU,were 41.6% (676/1 625),15.9% (259/1 625)and 19.1% (310/1 625).Carbon penicillium,resistance to carbon alkene sensitive penicillium alkene and extensive drug resistance rate of pseudomonas aerug-inosa isolated were 67.1% (1 090/1 625),31.6% (514/1 625)and 1.29% (21/1 625).Resistance to carbon penicillium al-kene the drug resistance of pseudomonas aeruginosa from penicillium carbon alkene sensitive serious,in addition to the poly-myxin B resistance to both comparative difference was statistically significant (χ2 = 12.617~ 12.617,P 60%.Conclusion Clinical pseudomonas aeruginosa had a high separation rate,mainly comes from the respiratory tract and the distribution of the ICU ward.Penicillium carbon alkene resistant pseudomonas aeruginosa than carbon penicillium sensitive resistance was serious,should pay close attention to carbon blue mould resistant pseudomonas aeruginosa resistance development,take effective measures of preventing transmission and infection of scientific use of antimicrobials,put an end to resistance to car-bon penicillium alkene and the spread of drug resistance pseudomonas aeruginosa .
