Analysis of the hospital infection and drug resistance of acinetobacter baumannii

Objective: To investigate the clinical distribution and drug resistance of Aba and offer the guidance for clinical application of antibiotics reasonably.Methods: The clinical distribution and drug resistance of Aba collected from our hospital in 2010 were retrospectively studied.Results: 1 690 strains of bacteria were isolated the whole year totally.Among them 282 strains were Aba and it holded second place.But Aba was in first place among the Gram-negative bacteria;282 strains of Aba were isolated from ICU(44.3%).The next were the samples isolated from the patients in departments of the Burn,the Respiratory Diseases and the Neurosurgery.Sputum specimens were the main samples(78%).The sensitive rates for polymyxin E were the highest(99.27%).And the next were imipenem and meropenem,but the drug-resistance rate of them were 68.68% and 68.57%.The drug-resistance rate of Aba for the other antibiotic was over 76%.Conclusion: Aba has a high infection rate clinically and the multiple-antibiotic-resistant situation is serious.Combined drug treatment is better to use clinically.The doctor should apply antibiotic reasonably,tighten disinfection isolation and aseptic technique,so as to prevent the spreading and prevalence of Aba.
