Objective To analyze the distribution of nosocomial infections and the distribution of pathogens in intensive care unit (ICU) patients so as to make corresponding countermeasures so as to effectively reduce the incidence of nosocomial infections. Methods A retrospective analysis of 370 ICU inpatients from January to December in 2009 was conducted. Results A total of 116 hospital infections occurred in 370 patients, with an infection rate of 31.35%. The majority of respiratory infections accounted for 64.65%, followed by urinary tract, blood and skin wounds. Gram-negative bacilli accounted for 72.17 %, Followed by gram-positive cocci accounted for 16.51%, fungi accounted for 11.32%. Conclusion The main respiratory tract in ICU hospital is respiratory tract. The common pathogens in ICU hospital are Pseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and fungi.
