A Review of Computer-aided Body Surface Area Determination: SAGE II and EPRI's 3D Burn Vision

Estimates of percent body surface area (%BSA) burns correlate well with fluid needs, nutritional requirements, and prognosis. Most burn centers rely on the Lund Browder chart and "rule of nines," to calculate the %BSA. Computer-based methods may improve precision and data analysis. We studied two new methods of determining %BSA: a two-dimensional Web-based program (Sage II) and a three-dimensional computer-aided design program (EPRI 3D Burn Vision). Members of our burn team found the Sage II program easy to use and found many of the features useful for patient care. The EPRI program has the advantage of 3D images and different body morphologies but required training to use. Computer-aided methods offer the potential for improved precision and data analysis of %BSA measurements.
