Abstract:
OBJECTIVE To analyze the etiological distribution and drug resistance characteristics of patients with respiratory failure and lung infection in EICU.METHODS The types of respiratory failure,the incidence condition of ventilator-associated pneumonia(VAP),the mortality rate,and the drug sensitivity of 129 pathogen strains which were isolated and cultured from the 110 cases with respiratory failure and pneumonia between Jan 2006 to Aug 2008 in EICU were analyzed.RESULTS Among the 110 patients,48 cases were died(the mortality rate of 43.6%).There were 28 cases(58.3%) of Ⅱ type respiratory failure,20 cases(41.7%) of Ⅰ type respiratory failure.Of 129 pathogens strains,there were 29 Gram-positive bacteria(22.5%) and 100 Gram-negative bacteria(77.5%).The major Gram-negative bacteria were Pseudomonas aeruginosa,Acinetobacter baumannii,and Klebsiella pneumoniae,and they showed generally higher multidrug resistance.Except minocycline,A.baumannii appeared strong multidrug resistance to the other 16 kinds of common antibiotics.The main Gram-positive bacteria were Staphyococcus haemolyticus,S.aureus and coagulase-negative staphylococci(CNS),and no evidence showed they resisted to vancomycin.CONCLUSIONS There are high mortality rate of patients with respiratory failure and lung infection if they suffered from compound infection.The main pathogens of the lung infection are Gram-negative bactiera,such as P.aeruginosa,A.baumanniiand K.pneumoniae in order,with high multidrug resistance.The main Gram-positive bacteria show no evidence resist to vancomycin.
