Abstract:
Objective To investigate pathogens distribution and their drug resistance of hospital acquired pneumonia (HAP) in local elderly paraplegic patients,and to help to gain experience in early using antibiotics.Methods One hundred and thirty six elderly patients diagnosed as HAP from January 2007 to December 2010 in our hospital were selected.Pathogens distribution and their drug resistance were detected.Results One hundred and fifty two pathogens are isolated from the 136 patients,and most of them are gram negative bacteria which accounts for 70.4％.The first three pathogens are Klebsiella pneumonia(24.3％),Escherichia coli (20.4％) and Pseudomonas Aeruginosa (18.4％).Gram-positive cocci accounts for 25.0％ in total pathogens,among them,staphylococcus aureus and streptococcus pneumoniae account for the most,and the number of Fungi is the fewest.Drug resistance rate of gram-negative bacteria is higher than that of Gram-positive bacteria.Gram-negative bacteria has higher resistance to ampicillin,cefoperazone,ciprofloxacin,levofloxacin and eotrimoxazole.Gram-positive bacteria has higher resistance to penicillin,cefazolin and gentamicin.Conclusion To elderly paraplegic HAP patients,the main pathogenic flora is gram-negative bacterium which shows multiple resistances.Being familiar with the features of pathogens and their drug resistance will provide better guidance on early treatment and improve prognosis of elderly paraplegic HAP patients.
