Abstract:Objective To explore the the relationship of bacterial infection,injury mechanism and extent of injury of hand trauma to guide the treatmentthrough the retrospective study.Methods The 239 cases of infection after hand injury from The Hand-Foot surgery of the Affiliated Hospital of Chengde Medical University were collected in 2011—2016.There were 181 males and 58 females,aged 4~77,with an average age of (42.96±12.60).Correlation analysis was performed on the injury mechanism,the injury degree,and the type of bacteria infected.Results From the 239 cases,rolling cutter and avulsion with severe hand injuriesaccounted for 21.8%,crush injury and bruise accounted for-23.4%.There were different types of bacteria after different grades,Gram-positive bacteriaaccountedfor 38.3% in Grade I.The Gram-positive and Gram-negative bacteria accounted for 36.7% and 40.8% in Grade Ⅱ.Infections were mainly Gram-negative bacteria,and accountedfor 65.8% and 71.9% in Grade Ⅲ and Ⅳ.There were significant differencesin between grade I~Ⅳ.The pathogenic bacteria Pseudomonas aeruginosa accountedfor 20.6%,and Staphylococcus aureus accounted for 14.7%.The bacteria were mainly Gram-negative.Conclusion The type ofbacterial changes with the severity of the injury.Gram-positive bacteria are the mainly type of patients with grade Ⅰ trauma.Gram-negative bacteria were the mainly type of patients with grade Ⅲ and Ⅳ trauma.In order to reduce the incidence of infection,the clinicians should choose antibiotics according to different grades of hand injuries.
