Objective: To explore four antibiotic regimens for the treatment of lower
respiratory tract infection, and analyze the clinical efficacy and cost of each regiment
by using the small cost method, so as to provide reference for clinical medication.
Methods: A total of 120 patients with lower respiratory tract infection were randomly
selected from the hospital, and those who did not meet the criteria were excluded.
They were randomly divided into four groups: A, B, C and D, the age ranged from 17
to 60 years old, with an average age of (38.5 ± 21.5) years. Four kinds of antibiotics,
ceftriaxone sodium, ceftizoxime sodium, azithromycin and levofloxacin, were used
to treat the four groups of patients respectively. Results: After treatment, there was no
significant difference between the four groups in clinical efficacy and adverse reactions
(p > 0.05). However, in terms of economy, the economy of ceftriaxone sodium and
levofloxacin is significantly better than that of ceftizoxime sodium and azithromycin
when the therapeutic effect is significant (p < 0.05). Conclusion: Through the
clinical treatment of four groups of patients, we found that ceftriaxone sodium and
levofloxacin were more cost-effective. Therefore, ceftriaxone sodium and levofloxacin
with excellent efficacy and cost should be selected in the treatment of lower respiratory tract infection.
