What is the best way to differentiate between a Trombley-Brennan terminal tissue injury (TB-TTI) and deep tissue injury (DTI)?
Mary: This is the most challenging because these injuries resemble one another. The difference is that a TB-TTI does not evolve as a DTI does. There may be an increase in surface area but no change in the appearance or type of tissue. A TB-TTI will look the same in color and appearance on day 3 or 5 as it does on day 1.
