Abstract:
Objective To analyze results of bacterial infection distribution and drug sensitivity monitoring in 414 patients with open extremity injuries caused by Wenchuan earthquake so as to provide advices for guiding utility of antibiotics in treatment of patients injured in natural disasters. Methods Bacterial culture of wound secretion substance and drug sensitivity monitoring were done in 414 patients with open extremity injuries. Results There were 12 patients (2.9%) with G+ coccobacteria, 66 (15.9%) with G- bacillus, 2 (0.5%)with G+ bacillus, 6 (1.5%) with multiplicitas infection(5 with dual infection and I with triplication infection). Main pathogenic bacteria were as follows: (1)G+cocco- bacteria including Staphylococcus epidermidis, Staphylococcus aureus and anthropo-staphylococci ; (2) G- bacillus including Aerobacter cloacae, banmanii, escherichia co]i, aerugo pseudomonas, proteusvul- gaffs and Ewingella americana. (3)G+ bacillus including bacillus subtilis. The drugs with high sensi0tivi- ty to G+ coccobacteria included vancomycin, rifampin, levofloxacin and cidomycin, but those with low sensitivity to G+coccobacteria included penicillin, ampicillin and erythremycin. The drugs with high sen- sitivity to G- bacillus included imipenem, amikacin, levofloxaciu and tenebrimycin, but those with low sensitivity to G-bacillus included ampicillin and piperacillin. Conclusions Patients with open ex- tremity injuries caused by earthquake have rather high bacterial infection rate, involving many kinds of in- fection strains. Therefore, we should do bacterial culture and drug sensitivity monitoring of wound excre- tion substance as early as possible to guide rational use of antibiotics.
