Background And Aims:
Calculating the precise total burn surface area is crucial when treating burn patients, particularly children. The Lund and Browder chart and Rule of Nines, 2-dimensional diagrams that are widely used, are subject to high interrater variance, and they can severely overestimate the burn area. Previously, the adult 3-dimensional burn area calculation mobile application was developed. Aiming to improve accuracy, a 3-dimensional pediatric burn surface area calculation mobile application ("3D PED BURN") was developed to overcome the limitations of the conventional methods.
Method:
Fifteen 3-dimensional pediatric burn surface area models based on detailed anthropometric measurements collected from 85 patients were developed and categorized into four age groups: <1 year; 1-4 years; 5-9 years, and 10-15 years. According to their weight and height, the models in each group were fractionated into large, medium, and small body sizes.
Result:
A precise and easy-to-use application was developed based on these data. This application is a promising and more accurate calculation tool for burn surface area in pediatric patients. Its low inter-rater variance makes it reliable for use by various healthcare personnel.
Conclusion:
The 3D PED BURN app is a pediatric 3D burn surface area calculation tool that is both accurate and simple to use.
