Bacterial infection resistance phenotype and drug sensitivity analysis in patients of hand-foot osteomyelitis
Objective To understand the types and drug resistance of bacterial infection in hospitalized patients of hand and foot surgery department,provide theoretical support for rational drug use in clinical practice.Methods The wounds and purulent secretions were inoculated and cultured on agar plates from hand and foot surgery department of a hospital from Jannary 2020 to June 2022,and verified by the kirby-Bcuer method.Results A total of 358 bacterial strains were detected.185 strains(51.39％)of Gram negative bacteria,including 115 strains(62.16％)of Enterobacteriaceae,172 strains(48.04％)of Gram positive cocci,including 140 strains(81.40％)of Staphylococcus aureus,27 strains(19.29％)of methicillin-resistant Staphylococcus aureus,1 Gram positive bacterial strain(0.28％).The resistance rate reached about 80％to Penicillin and first generation Cephalosporins of Enterobacteriaceae.The resistance rate reached 96.83％to Piperacillin of Penicillin antibiotics of Staphylococcus aureus.Conclusion There were many types of bacterial infections and high resistance rates in patients of hand and foot surgery department,antibiotics should be used reasonably to avoid the generation and spread of drug-resistant strains.
