A Swine Burn Model for Investigating the Healing Process in Multiple Depth Burn Wounds.

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Dermatology

Background:

• Burn wound healing presents complex challenges, including evolving tissue damage and poorly understood phenomena like the "shadow zone."
• Current diagnostic and therapeutic strategies for burns require significant advancement.
• Innovative treatments like nanoparticle dressings and artificial skin are under development but need robust testing models.

Purpose of the Study:

• To establish a reliable and reproducible protocol for creating multi-depth burn wounds in Yucatan minipigs.
• To provide a relevant animal model for long-term burn wound healing studies.
• To facilitate the evaluation of new diagnostic tools and therapeutic interventions for thermal burns.

Main Methods:

• Development of a standardized protocol for inducing multi-depth thermal burns in Yucatan minipigs.
• Utilizing Yucatan minipigs due to their skin structure similarity to humans, including melanin pigmentation.
• Implementing a long-term follow-up strategy to observe wound healing dynamics.

Main Results:

• A reliable and reproducible protocol for creating multi-depth burn wounds in Yucatan minipigs was successfully established.
• The Yucatan minipig model demonstrated suitability for studying burn wound healing, including in subjects with high phototypes.
• The model allows for extended observation periods, crucial for evaluating long-term healing processes and therapeutic efficacy.

Conclusions:

• The developed Yucatan minipig model offers a valuable platform for advancing burn wound research.
• This model supports the investigation of burn pathophysiology and the testing of novel treatments.
• Further research utilizing this model can lead to improved burn diagnosis and patient care.
