Abstract:
Objective To explore the significance of sample cultivation and drug resistance of the patients in PICU with severe lower respiratory tract specimens.Methods 1 107 pathogenic bacteria of lower respiratory tract samples collected were analyzed and the drug resistance was kept watch on.Results A total of 1107 samples were cultured into 948 strains of pathogens,with the positive rate of 85.64%,and 616 strains of Gram negative bacteria accounting for 64.98%,of which 145 strains of Pseudomonas aeruginosa(15.30%),Klebsiella pneumoniae 135(14.24%),Acinetobacter spp 131(13.82%),large intestine Egypt Greek bacteria 89(9.4%);Gram positive cocci 129(13.61%),the main pathogen was staphylococcus aureus and Fungi 203(21.41%),the main pathogen was candida albicans.Carbapenems was the most active antibiotics for gram negative bacill,and vancomycin for gram positive cocci.Conclusion Infectious bacteria have high selectivity to the sensitive antibiotics,and doctors should carefully use antibiotic according to the susceptibility test results in order to reduce hospital infection and the emergence and spread of resistant strains.
