Quantitative assessment of burn injury in porcine skin with high-frequency ultrasonic imaging.
Early excision and grafting of full thickness burns has been shown to decrease morbidity and mortality. Errors made in assessing acute burn depth are common and result in prolonged hospitalization in expectant healing of full-thickness burns and in unnecessary excision and grafting of potentially regenerative partial-thickness burns. High-frequency ultrasonic imaging may be a noninvasive, convenient means of quantitating burn depth. ⋯ Direct histologic comparison was made with each scan plane. Average burn and normal skin depth measurements were made by independent observers for 34 scans and corresponding histologic sections. A significant correlation was achieved between burn depth and percent burn (burn depth/adjacent normal skin depth) as measured by ultrasound and histology (R = 0.90, t = 11.2, P less than .001).
