Abstract Objective: To provide a more accurate guidance for the control of hand-surgical infections and clinical rational drug use by retrospective analysis of the cases of hand injury infections with different injury mechanisms. Methods: The specimens of patients with hand injury from different injuries were collected from January 2014 to December 2016. The bacteria were cultured, the pathogens were isolated, and the distribution and drug resistance of the strains were statistically analyzed. Results: A total of 582 strains of bacteria were isolated, of which 398 were Gram-negative bacteria, accounting for 68.38%, and 184 were Gram-positive bacteria, accounting for 31.62%. There were differences in the types of infected bacteria among different injury mechanisms. Among the different injury mechanisms, the detection rate of Pseudomonas aeruginosa was 127 (21.82%), followed by 87 Staphylococcus aureus (14.95%). Different types of wounds detected different types of bacteria, but the main pathogens were common bacteria in nosocomial infections and the difference in drug resistance of the same pathogens was not significant. Conclusion: The distribution of fungi in different hand injury injuries is nosocomial infection with Gram-negative bacteria. Different kinds of injury mechanisms need to prevent different types of bacteria. Severe trauma should be based on Gram-negative bacteria, but for postoperative Prevention, different injury mechanisms, especially special types of trauma should be used as a reference for the use of antibacterial drugs in bacterial culture and drug susceptibility testing.
