2007-2011年燒傷患者細菌分布及耐藥性分析
[Abstract]:Objective to analyze the changes of bacterial distribution and drug resistance in burn patients for 5 years and to provide reference for prevention and treatment of infection in the future. Methods the bacteria isolated from 537 burn patients from January 2007 to December 2011 were collected and the distribution and drug resistance of bacteria were analyzed. Results there were 637 gram-negative bacilli (62.76), and 323 gram-positive cocci (31.82%) showed a decreasing trend. Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter baumannii, Klebsiella pneumoniae, Escherichia coli, Enterobacter cloacae, coagulase negative Staphylococcus, Proteus mirabilis were the first 8 bacteria in the detection rate. The resistance rates of Pseudomonas aeruginosa to ceftazidime, cefoperazone / sulbactam and imipenem were 34.27%, 40.88% and 26.29%, respectively. Acinetobacter baumannii was sensitive to cefoperazone / sulbactam (29.51%) and widely resistant to other antibiotics. The detection rates of multidrug-resistant/pandrug-resistant Pesudomonas aemginosa (MDR / PDR-PA) and Carbapenems-resistant / pan-resistant Acinetobacter baumannii (CRPDR-AB) increased significantly. MRSA was mainly multidrug resistant staphylococcus aureus. The drug resistance rates of MRSA to vancomycin, linazolamine and teicoplanin were 0 0, 5. 71. MRSA respectively. The positive rate of MRSA decreased. Conclusion the phenomenon of multidrug resistance / pan-resistance of the main bacteria is becoming more and more serious, which should be paid more attention to and used rationally in clinic.
