An Optical Tomography-Based Score to Assess Pediatric Hand Burns

Area of Science:

• Medical Imaging
• Dermatology
• Pediatric Surgery

Background:

• Pediatric hand burns present unique challenges in wound assessment and management.
• Accurate burn depth determination is crucial for predicting healing outcomes and guiding treatment strategies.
• Optical coherence tomography (OCT) offers high-resolution, non-invasive imaging of tissue microstructure.

Purpose of the Study:

• To characterize the morphologic patterns of pediatric hand burns using optical coherence tomography (OCT) and dynamic OCT (D-OCT).
• To develop and validate a novel OCT-based scoring system for assessing pediatric hand burn depth.
• To evaluate the score's ability to predict wound healing and the need for skin grafting.

Main Methods:

• Prospective examination of 67 hand burns in 48 pediatric patients (0-15 years) using OCT and D-OCT.
• Development of a scoring system based on OCT findings such as epidermal loss, dermal pattern disruption, and vascular changes.
• Retrospective calculation of score values and correlation with clinical healing outcomes and need for grafting.

Main Results:

• A specific OCT burn score (score of 4) was strongly associated with spontaneous healing without skin grafting (97% positive predictive value).
• Higher scores (5 and above) indicated deeper wounds requiring delayed healing or skin grafting, with 80% agreement in medical healing assessment.
• OCT and D-OCT provided valuable supplementary information for assessing pediatric hand burns.

Conclusions:

• OCT and D-OCT imaging are clinically useful tools for evaluating pediatric hand burns.
• The developed OCT burn score demonstrates potential in supporting clinical decision-making for burn wound management.
• Utilizing the OCT burn score may lead to improved patient outcomes and reduced hospital stays for pediatric burn patients.
