The problem addressed by the research reported on herein is concerned with the development and testing of two different non-invasive instruments for the early characterization of burns. An electro-optic burn depth indicator developed by the author quantitatively measures the red, green, and infrared reflectivity of a burn. We proposed to test this instrument on burns during the first few days post-burn, and determine whether this instrument has value in diagnosing burn depth when used in that time frame. The second aspect of our program is concerned with developing a new instrument, the 20 MHz pulsed Doppler ultrasound skin blood flow indicator. This instrument was designed to detect and measure the characteristics of skin blood flow as a function of depth below the surface of a burn wound. It is expected that this information can be used to evaluate zones of stasis and predict eventual burn wound healing. The research is directed toward the development of inexpensive portable instruments which can be used as aides in determining burn depth and estimating time to healing and are intended to be used as diagnostic tools to help characterize burn wounds, select the appropriate treatment modality, and to monitor healing processes.
