Abstract:
OBJECTIVE To investigate the distribution of bacteria in general ICU then discuss the susceptible factors and the treatment.METHODS A retrospective analysis of clinical information was performed on 123 patients diagnosed infection who stayed in ICU from May 2002 to May 2004.RESULTS Most of bacteria resulted in infection of general ICU were Gram-negative(62.88%) and then Gram-positive(19.65%). Fungal infection accounted for 17.47%.Pseudomonas aeruginosa occupied the highest percentage among Gram-negative bacteria.Most of Gram-positive bacteria were Staphylococcus aureus and all of them were MRS.The infection site in ICU focused on lower respiratory tract(89.09%).The second was urinary tract(11.79%).CONCLUSIONS Most of the bacteria causing infection in general ICU locate in respiratory tract.They are mainly Gram-negative.All of the Gram-positive bacteria are MRS.The risk factors of hospital-acquired infection are related with patient′s age,underlying disease,intensive care time,ventilation time and invasive operation.
