Tissue Wound Team

As experts, we know that effective Wound Bed Preparation (WBP) relies heavily on accurate tissue assessment across the healing continuum. While these characters are fun, the color-coding represents critical stages in tissue viability and the proliferative phase.

Here is a quick scientific breakdown of the spectrum we manage daily:

⚫ Black (Necrotic/Eschar): Devitalized, non-viable tissue. It’s a physical barrier to granulation and a breeding ground for bioburden. The priority is debridement to uncover viable tissue beneath.

🟡 Yellow (Slough/Fibrin): Often indicates persistent inflammation or infection. This mixture of proteinaceous material, fibrin, and debris requires effective cleansing and appropriate dressing selection to transition the wound out of a stalled inflammatory state.

🔴 Red (Granulation): The “Healing Hero.” Highly vascularized connective tissue indicating the proliferative phase. It is healthy but fragile; our goal is to protect it and maintain an optimal moist healing environment.

🟣 Pink (Epithelialization): The final stage. Migration of new keratinocytes across the surface of the granulation tissue to close the defect. This new tissue is delicate and requires protection from shear and friction.

Visualizing these stages helps simplify complex pathophysiology when educating patients or training junior staff.
