ABSTRACT
OBJECTIVE To explore the clinical and etiological characteristics in patients with ventilator-associated pneumonia(VAP) in emergency intensive care unit(EICU),and improve the prevention and treatment level of VAP.METHODS To analyze the clinical information of 54 patients with VAP,and to compare the clinical information with the incidence rate of VAP.Bacterial culture of airway secretion and drug sensitive test were used to analyze etiology.RESULTS Totally 148 patients were enrolled in this study,of which 54 were diagnosed as VAP.The incidence rate of VAP group was 36.5%.Respirator used time of VAP group was obviously longer than that of non VAP one.Antibiotic prophylaxis could not lower the incidence rate.A total of 59 pathogen strains were isolated by bacteria culture.The major pathogenic bacteria in VAP were Pseudomonas aeruginosa(22.0%),Acinetobacter baumannii(16.9%),Staphylococcus aureus(15.3%),Escherichia coli(10.1%),and Klebsiella pneumonia(10.1%).CONCLUSIONS VAP is one of the significant reasons for failed mechanical ventilation treatment.To prevent and treat VAP should pay attention to disinfection and aseptic manipulation,and make the rational use of antimicrobial agents.
