Abstract
Objective To investigate the distribution and drug resistence of the bacteria causing hospital infec-tions in Orthopedics department ,Sichuan Provincial Orthopedic Hospital ,and provide evidence for clinical rational use of antibiotics .Methods n 2012 ,outpatient and inpatient isolated 337 strains of pathogenic bacteria were analyzed retrospectively .Results The pathogenic bacteria including Gram-positive cocci 122 ,accounting for 36 .20% ,Gram-negative bacteria 180 ,accounting for 53 .41% ,fungi 35 ,accounting for 10 .39% .Staphylococcus aureus (79 .51% ) were the most common pathogen in Gram-positive cocci ;Gram-negative bacteria were mainly consist of Escherichia coli (31 .67% ) ,Pseudomonas aeruginosa (26 .67% );Fungi were mainly consist of candida albicans .Conclusion Due to long-term heavy use of antibiotics ,resulting in changing antibiotics resistance ,and antimicrobial susceptibility test and bacterial cultures should be taken before using antibacterial agents .The rational use of antibacterial agents can slow down the resistance of pathogenic bacteria ,reducing the incidence of infection .关键词
