Objective To investigate the distribution and drug resistance of pathogenic bacteria of patients with traumatic limbs fracture in No.178 Hospital of Haikou from 2013 to 2016, and to provide reference for clinical rational drug use.Methods Inpatients (3 841 cases) with traumatic limbs fracture in No.178 Hospital of Haikou from March 2013 to March 2016 were analyzed retrospectively. The data of 83 cases of patients infected by pathogenic bacteria was selected, and the distribution and drug resistance of pathogenic bacteria were analyzed retrospectively.Results Totally 89 strains of pathogens were isolated, in which Gram-negative bacteria were 28 strains (31.46%), main of them were Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Enterobacter aerogenes. Gram-positive bacteria (61 strains) accounted for 68.54%, and main of them were Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, and Enterococcus avium. The resistance rates of E. coli against ampicillin, levofloxacin, sulbactam, extended spectrum β lactamases, ceftriaxone, and cefazolin were 70.00% — 100.00%. E. coli was sensitive to ertapenem, piperacillin, amikacin, erythromycin, and imipenem. The resistance rate of E. cloacae against imipenem was 0.00%, and against other antibiotics were 25.00% — 100.00%. In Gram-positive bacteria, S. aureus and S. epidermidis were sensitive to ampicillin, dalfopristin, linezolid, tigecycline, and macrodantin. S. epidermidis was also sensitive to ciprofloxacin, and the resistance rate was 0.00%. The sensitive rates of S. aureus and S. epidermidis against penicillin were 100.00%. Besides, the sensitive rates of S. aureus and S. epidermidis against other antibiotics were less than 50.00%. Conclusion The main pathogens of patients with traumatic limbs fracture in No.178 Hospital of Haikou is Gram-positive bacteria. It is important to choose rational antibiotics according to the drug sensitive test and enhance the detection of drug resistance.
