Summary
A new computerized system accurately measures burn size on a diagram, offering a fast and simple alternative to manual methods for calculating body surface area percentage. This digital approach shows excellent correlation with traditional techniques.
Area of Science:
- Medical technology
- Burn management
- Digital health
Background:
- Accurate estimation of burn surface area is critical for effective patient management and treatment.
- Traditional methods like the Lund and Browder chart can be time-consuming and prone to variability.
Purpose of the Study:
- To develop and evaluate a novel microcomputer system for quantifying burn percentage.
- To assess the accuracy and efficiency of computerized planimetry compared to manual charting.
Main Methods:
- A microcomputer system was designed for users to draw burn contours on a digital diagram.
- The system automatically calculates the percentage of body surface area affected by the burn.
- 148 weekly burn diagrams from 59 patients were analyzed, with burn sizes ranging from 1% to 71%.
Main Results:
- The computerized system demonstrated excellent correlation with the manual Lund and Browder chart method (correlation coefficient = 0.962, p < 0.0001).
- The system provides rapid and simple data recording and calculation of total burn percentage.
- Mean burn size analyzed was 23.7% body surface area.
Conclusions:
- Computerized planimetry offers a reliable and efficient method for burn area assessment.
- This digital approach provides a valuable tool for burn data management and clinical decision-making.
- The system's accuracy and ease of use make it a strong alternative to conventional manual methods.
