Abstract：Objective To explore the relationship between severity of burn and pathogen infection wound-blood transmission evaluated based on Ryan score，and to provide evidence for rational and systematic application of antibiotics in burn patients.Methods A retrospective analysis was made of 230 severely burned patients admitted to our hospital from April 2014 to April 2018.All patients were divided into four groups （0，1，2，3 groups）according to Ryan score for descriptive statistical analysis.The relationship between severity of burn and wound-blood transmission of pathogen infection was independent variable and severity of burn was dependent variable.The influence of Ryan score on wound-blood transmission was analyzed and evaluated.The positive rate of wound culture in patients with positive blood culture was analyzed based on Ryan score.Results The positive rate of wound culture in the four positive bloodborne groups were 15.7%，63.8%，82.5%and 36.3%.The bacterial flora of wound culture was consistent with that of blood culture in severely burned patients.There was a certain correlation between the blood-borne pathogenic bacteria and the severity of burn （OR=0.124，95%CI=0.029-0.650）.The blood-borne transmission of pathogenic bacteria in wounds was a correlative factor of severity of burn.Conclusion Ryan score can effectively evaluate the relationship between the severity of burn and the spread of pathogens to blood in severely burned patients.
