Summary
This study developed a reliable animal model and histopathologic scale to accurately measure burn depth. This standardized method improves consistency and comparability in burn research.
Area of Science:
- Biomedical Engineering
- Dermatology
- Veterinary Science
Background:
- Current burn classification (first-, second-, third-degree) is imprecise.
- Accurate burn depth assessment is crucial for prognosis and treatment.
- Standardized methods are needed for reliable burn research comparisons.
Purpose of the Study:
- To standardize a reproducible animal burn model.
- To develop a precise histopathologic method for burn depth description.
- To improve the reliability and comparability of burn studies.
Main Methods:
- Utilized a swine model with controlled burn injuries (varying temperature and exposure time).
- Employed histopathologic evaluation with hematoxylin and eosin staining.
- Measured five dermal parameters using an ocular microtome and assessed inter/intraobserver reliability.
Main Results:
- Burn depth correlated significantly with temperature and exposure time (ANOVA, p < 0.001).
- The animal burn model demonstrated high consistency (Pearson correlation, 0.88-0.95).
- Excellent inter- and intraobserver reliability was achieved for all measurements (0.91-0.99).
Conclusions:
- A simple, reproducible animal burn model and histopathologic scale were established.
- This method allows for precise measurement of burn depth.
- The findings facilitate standardization and comparison in future burn research.
