Paper Abstract

This research program successfully developed a real-time video imaging system (the Imaging Burn Depth Indicator, or IBDI) which can discriminate areas of burn wounds expected to heal in three weeks or less from the day of injury from those areas not expected to heal in that time period. The analysis can be performed on or about the third day post-burn on debrided burn wounds. Early evaluation of burn healing probability is a crucial factor in the decision to tangentially excise the burn wound. The IBDI measures the reflectivity of the burn wound in the red, green, and near infrared wavelength bands, which data correlate with burn healing probability. The instrument uses an algorithm established in an earlier study to translate the optical data into burn healing probabilities. The IBDI produces two types of images: a true-color image of the burn and a false-color image of the burn. The false-color image consists of up to four colors, each of which indicates a distinct range of probability that the area of the burn so colored will heal within 21 days. Over 100 burn wound sites were studied. Burn sites were evaluated on day three post-burn by our instrument and by the attending physician. Of 55 sites considered to be of intermediate depth, the IBDI predicted the healing outcome accurately in 84% of the cases. By comparison, the predictions of burn surgeons supervising the care of these patients were accurate in 62% of the cases.
