Clinical Analysis Of 193 Cases Of Pneumonia In Intensive Care Unit

Objective: To study the clinic characteristics of the patients with pneumonia in intensive-care-unit(ICU),as well as epidemiologic fetures and the distribution of bacteria.Methods: Retrospectively analyzed 193 pneumonic patients admitted to Fujian Provincial Hospital ICU from June 2007 to December 2008. Results: The average age of the 45 HAP patients is【mean age ( 70.76±16.93) years】,【mean age (66.73±15.80) years】for the 148 CAP patients. 205 strains of bacteria were isolated from 134 patients. Most patients of the two groups had basic diseases, at least one kind of comorbidity, and the use of H2 blockers was more frequently. A neurological comorbidity and intensive operations such as tracheotomy, were found quite frequently among the patients with HAP than CAP.(p<0.05)Intensive operations, complications and mortality, were found more frequently among the patients with HAP. Multivariate analysis showed that severe pneumonia and moderate anemia or severe were important prognostic factors in the prognosis of pneumonia. A total of 125 strains of Gram-negative bacteria were detected, 30 of which were Gram-positive bacteria 30, 50 were fungi ; 96 of those patients had more than double pathogen infection. Pseudomonas aeruginosa, Among the bacteria ,Klebsiella pneumoniae and Escherichia coli, were the main Gram-negative bacteia types, while Staphylococcus aureus was the predominant Gram-positive bacteria. What is more, it suggested a high isolated multi-drug resistant rate (45.27%) was found in the hospital.Conclusion: Patients with pneumonia in ICU were found to had more comorbidity illnesses and complications. The main pathogen was gram negative bacilli. Lots of the pathogens were multi-drug resistant.
