Accurate depth assessment of burn wounds is a critical task to provide the right treatment and care. Currently, laser Doppler imaging is able to provide better accuracy compared to the standard clinical evaluation. However, its clinical applicability is limited by factors like scanning distance, time, and cost. ⋯ Histological results obtained from trichrome staining were used as ground-truth. The combined performance of RS-OCT reported an overall average accuracy of 85% and ROC-AUC=0.94, in distinguishing the burn wounds. The significant performance on ex vivo skin motivates to assess the feasibility of combined RS-OCT in in vivo models.

Partial thickness wound: Does mechanism of injury influence healing?
Wound healing is a complex multistep process which is temporally and spatially controlled. In partial thickness wounds, regeneration is possible from the stem cells in the edges of the wound and from the remnants of the epidermal appendages (such as hair follicles and sebaceous glands). This study examines whether the mechanism of injury influences healing of wounds of similar depth. ⋯ The thickness of the dermis of partial thickness excisional scar was greater than that of the adjacent unwounded skin. The neo-dermis of the burn scar was even thicker, with the collagen arranged more compactly and disorganised compared to excisional scar and normal skin. This study provides evidence that the mechanism of injury does influence wound healing and the resultant scarring.

Measuring gastric residual volumes (GRV) is common in intensive care units (ICU) in patients receiving enteral nutrition (EN) and are a common source of feeding interruptions. Interruptions in EN yield adverse outcomes and are an area of improvement in burn care. The objectives of this study are to summarize the literature's ICU GRV practices and offer practical suggestions to GRV management in the burn patient. ⋯ We advocate a GRV threshold of 500mL should be used to optimize the benefits of EN in burn ICUs. A single incident of elevated GRVs should not mandate immediate EN rate reduction or cessation but should prompt a thoughtful examination of secondary causes of gastrointestinal intolerance. Randomized controlled trials are needed to define the ideal GRV threshold and re-evaluate its role in burn care.
