Objectives: This study was explore the distribution of the bacteria and their sensibility to antibiotics in hospital-acquired pneumonia.
Methods: One hundred and ninety-six bacterium species were collected in patients with the hospital-acquired pneumonia to make sputum culture. The sensibility of the bacteria to antibiotics were examined by KB paper method and the minimal-inhibitory-concentration by gel double multiple dilute method.
Results: Most of the G- bacteria were pseudomonas aeruginosa (30%) and klebsiella bacillus (22%). Most of the G+ bacteria were staphylococcus epidermidis (14%) and staphylococcus aureus (12%). G- bacteria were sensitive to impienem(98%), cefoperazone(90%), ceftriaxone(90%), leftazidime(92%), ciprofloxacin(90%), and amikacin(89%). The sensibility of vancomycin to G+ bacteria was 100%.
Conclusions: The pseudomonas aeruginosa, klebsiella bacillus, staphylococcus epidermidis, and staphylococcus aureus are the most important bacteria in patients with hospital-acquired pneumonia. Imipenem, cefoperazone, ceftriazone, leftazidime, ciprofloxacin, amikacin, and vancomycin are effective antibiotics for treating hospital-acquired pneumonia.
