Abstract:
OBJECTIVE To evaluate bacterial drug resistance detection value in lower respiratory tract infection treatment.METHODS The data of distribution and antimicrobial resistance of clinical strains in sputum samples in patients with lower respiratory tract infection within some periods were collected and analyzed by WHONET software.Meanwhile,the delivery rates and detection positive rates of clinical species and antibiotics application status in clinic were retrospectively analyzed.RESULTS The delivery rates and detection positive rates of clinical species in patients with lower respiratory tract infection within some periods were 67.8% and 55.9%,respectively.The proportion of Gram-negative bacilli and Gram-positive cocci was 82.39% and 14.18%,respectively.Different drug resistance was displayed in different pathogenic bacteria.Resistant rate of Enterobacteriaceae bacteria and non-ferment bacteria against ciprofloxacin and piperacillin/tazobactam was 47.8%,34.8%and 31.5%,44.7%,respectively and resistant rate of S.aureus against levofloxacin was 63.9%.CONCLUSIONS Although the pathogenic bacteria in patients with lower respiratory tract infection show higher drug resistance to general antibiotics,most of patients with lower respiratory tract infection are treated according to clinical experience of doctors,not based on the results of bacterial culture and antimicrobial susceptibility test.Therefore,the results of bacterial culture and antimicrobial susceptibility test do not play a proper role to direct anti-infective therapy in clinic.
