“…High-frequency ultrasound detects medium changes in which a sound wave is reflected in tissue and an interface is created. 11 The interpretation of this interface can be difficult and it is hard to discern whether the deeper signals are deep dermal plexus blood flow or in fact the dermal-fat interface. 10 An acoustic interface in burn tissue suggests that there is a certain ''cutoff'' level within the skin whereby everything above a level is nonviable and below is viable.…”

“…47 Eschar and interstitial edema have made it difficult for other technologies, such as laser Doppler and ultrasound, to assess blood flow accurately. 3,4,10,11 NIR can penetrate deep into the tissue and can reach depths from 2 to 10 cm, which is appropriate for the interrogation of skin. 48,49 In addition, NIR is able to measure the water concentration and is therefore not affected by edema.…”

The diagnosis of burn depth is based on a visual assessment and can be subjective. Near-infrared (NIR) spectroscopic devices were used preclinically with positive results. The purpose of this study was to test the devices in a clinical setting using easily identifiable burn wounds. Adult patients with acute superficial and full-thickness burns were enrolled. NIR point spectroscopy and imaging devices were used to collect hemodynamic data from the burn site and an adjacent unburned control site. Oxy-hemoglobin and deoxy-hemoglobin concentrations were extracted from spectroscopic data and reported as oxygen saturation and total hemoglobin. Sixteen patients (n=16) were included in the study with equal numbers in both burn wound groups. Point spectroscopy data showed an increase in oxygen saturation (p<0.0095) and total hemoglobin (<0.0001) in comparison with the respective control areas for superficial burn wounds. The opposite was true for full-thickness burns, which showed a decrease in oxygenation (p<0.0001) and total hemoglobin (p<0.0147) in comparison with control areas. NIR imaging technology provides an estimate of hemodynamic parameters and could easily distinguish superficial and full-thickness burn wounds. These results confirm that NIR devices can successfully distinguish superficial and full-thickness burn injuries.

“…This problem has motivated research on the development of a wide variety of methods and technologies to aid the clinical assessment of burns, including multispectral optical reflection imaging [4], Indocyanine green dye fluorescence techniques [3,5], Nuclear Magnetic Resonance (NMR) imaging [6], Laser Doppler Imaging (LDI) [7], ultrasonography [8], contact dielectric measurement at radio frequencies [9], Polarization-Sensitive Optical Coherence Tomography (PS-OCT) [10], and near infrared spectroscopy [11,12]. However, widespread adoption of the aforementioned techniques in routine patient care is significantly hindered by practical concerns for accuracy, cost effectiveness, and compatibility in clinical environments [2].…”

We present sub-millimeter wave reflectometry of an experimental rat skin burn model obtained by the Terahertz Time-Domain Spectroscopy (THz-TDS) technique. Full thickness burns, as confirmed by histology, were created on rats (n = 4) euthanized immediately prior to the experiments. Statistical analysis shows that the burned tissue exhibits higher reflectivity compared to normal skin over a frequency range between 0.5 and 0.7 THz (p < 0.05), likely due to post-burn formation of interstitial edema. Furthermore, we demonstrate that a double Debye dielectric relaxation model can be used to explain the terahertz response of both normal and less severely burned rat skin. Finally, our data suggest that the degree of conformation between the experimental burn measurements and the model for normal skin can potentially be used to infer the extent of burn severity.

The assessment of burn depth, and as such, the estimation of whether a burn wound is expected to heal on its own within 21 days, is one of the most important roles of the burn surgeon. A false-positive assessment and the patient faces needless surgery, a false-negative one and the patient faces increased length of stay, risks contracture, and hypertrophic scar formation. Although many clinical signs can aid in this determination, accurate assessment of burn depth is possible only 64 to 76% of the time, even for experienced burn surgeons. Through the years, a variety of tools have become available, all attempting to improve clinical accuracy. Part 1 of this two-part article reviews the literature supporting the different adjuvants to clinical decision making is, providing a historical perspective that serves as a framework for part 2, a critical assessment of laser Doppler imaging.
