An analysis of the characteristics of etiology and drug resistance of nosocomial infection in the neurosurgery intensive care unit / 医学研究生学报

ABSTRACT

Objective: To investigate the characteristics of etiology and drug resistance of nosocomial infection in the neurosurgery intensive care unit(NICU),and provide useful information for clinical practice.Methods: We analyzed the clinical data of 179 cases of nosocomial infection among 1 163 patients admitted in the NICU from June 2005 to March 2007.Results: From the 179 patients,346 strains of bacteria were obtained,of which Gram's negative bacili accounted for 52.89%,Gram's positive cocci 38.15% and fungi 8.96%.Of the diagnosed nosocomial infections,83.80% involved the lower respiratory tract,10.61% the urinary tract,2.79% the blood vessels,1.68% the central nervous system and 1.12% the hematological system.Conclusion: To reduce nosocomial infections in the NICU,emphasis should be placed on the control of lower respiratory tract infection as well as on the prevention and treatment of Gram's positive coccus infection in the acute stage and Gram's negative bacillus infection in the later stage.Intensified prevention measures based on the standard ones could help to get the drug-resistant strains under control.
