Abstract: Objective:To investigate the application effects of real-cause intervention in the management of pediatric deep burn scar.Methods:A total of 60 cases were selected in the 1-6 years of deep burn rehabilitation,of which 30 were treated as control group in October to December 2015,and 30 cases were treated as observation groups in March to April 2016.The control group was implemented with routine rehabilitation scar management guidance,and the observation group was implemented with real-cause intervention scar management guidance.The implementation rate of scar management,degree of scar hyperplasia,muscle contracture and joint dysfunction between two groups were compared.Results:At discharge and after 6 months of discharge,the implementation rate of scar management in observation group was significantly higher than that in control group(P<0.01),and the degree of scar hyperplasia,muscle contracture and joint dysfunction in observation group were better than those in control group(P<0.05 to P<0.01).Conclusions:The real-cause intervention in the management of pediatric deep burn scar can improve the implementation rate of scar management,and reduce the degrees of scar hyperplasia,muscle contracture and joint dysfunction.
