Conventional Versus Regenerative Methods for Wound Healing: A Comparative Experimental Study on a Sheep Model.

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Wound Healing Research

Background:

• Wound healing is a complex biological process.
• Chronic wounds, often linked to diabetes and vascular issues, present significant healing challenges.
• Investigating novel therapeutic approaches is crucial for improving patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of conventional and regenerative wound healing strategies.
• To compare treatments including sterile gauze, chlorhexidine, sodium hypochlorite, micronized dermis system, and dermal matrix.
• To assess wound healing progression in a sheep surgical wound model.

Main Methods:

• Six Bergamasca sheep with full-thickness skin lesions were utilized.
• Wounds were treated with five different methods: sterile gauze, chlorhexidine, sodium hypochlorite, micronized dermis system, and dermal matrix.
• Healing was monitored for 42 days via wound dimensions, exudate analysis, and histopathology.

Main Results:

• All wounds achieved complete healing by day 42.
• Micronized dermis system and dermal matrix showed enhanced exudate characteristics and collagen reorganization.
• Histological findings indicated earlier neovascularization and better hair follicle reconstitution with regenerative treatments.

Conclusions:

• Regenerative approaches (micronized dermis, dermal matrix) improve wound healing phases, exudate control, and tissue regeneration.
• These methods did not accelerate acute wound healing compared to conventional treatments.
• Further research is warranted to explore their potential in managing chronic wounds.
