The Distribution of Pathogenic Bacteria and Drug Resistance Monitoring of Senile Patients with Infection in Bone Surgery

Objective To analyze the distribution of main pathogenic bacteria and drug resistance of senile patients with infection in bone surgery so as to provide a reference for clinical use of antibiotic drugs. Methods 300 cases of senile orthopedic patients admitted in our hospital from April, 2011 to April, 2013 were randomly selected. Secretion samples were collected from the wound of the patients for bacteria culture and bacteria identification, and drug sensitive test was conducted. Results Of the 300 cases of patients, a total of 298 strains of bacteria were detected, including 142 strains of gram negative bacteria(47.7%), 150 strains of gram positive bacteria(50.3%), 6 strains of fungi(2%). Conclusion The drug resistance of nosocomial infection pathogens is relatively complex, which changes quickly, so appropriate antibiotic drugs for the treatment of senile orthopedic patients, should be chosen in accordance with the pathogen resistance test and the result of appraisal strictly in order to reduce the infection rate of the patients.
