Abstract

Abstract: Objective: By analyzing the distribution and drug resistance of common pathogen in different sites in plastic surgery to provide reference for clinicians to choose the best antibacterial treatment plan. Methods: Pathogens of postoperative infection in plastic surgery from January 2011 to December 2021 were retrospectively analyzed to determine the species and quantity, and to access the trend of each pathogen's detection rate. The antibiotic sensitivity and distribution characteristics of common pathogens were studied in conjunction with the site of infection. Results: A total of 1709 bacterial strains were detected, including 1244 gram‐positive bacterial strains and 465 gram‐negative bacterial strains. The main pathogen of perineum was Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa), while Staphylococcus aureus (S. aureus) was the most common pathogen in the other infected sites. The detection rate of methicillin‐resistant S. aureus (MRSA) and methicillin‐resistant coagulase‐negative staphylococcus (MRCNS) was on the rise from 2011 to 2021. No S. aureus and coagulase‐negative staphylococcus ( CoNS ) strains were resistant to vancomycin. The sensitive rate of S. aureus from all parts and CoNS from all sites except lower limbs and mandible was higher than 80% to linezolid. The resistance rate of S. aureus and CoNS in all parts to penicillin, clindamycin, and erythromycin was high. The susceptibility rate of CoNS in lower mandible was high to gentamicin. Conclusions: Staphylococcus aureus was the primary pathogen of gram‐positive bacteria in all site of plastic surgery except perineum, followed by CoNS . The distribution and drug resistance of pathogen in different infection sites were different. We should formulate more accurate and reasonable antibacterial programs according to drug resistance results of various parts to reduce the emergence of resistant strains and effectively prevent and control infection.
