🩹 Pathology Series: Wound Healing | Phases, Mechanisms & Clinical Aspects
Welcome back to Pulse Academy’s Pathology Series! In today’s video, we dive into wound healing, a critical biological process that restores tissue integrity after injury. This high-yield topic is essential for understanding both general pathology and surgical principles 🩺.
What you’ll learn in this video:
• What is Wound Healing?
• Definition and significance in tissue repair 🔄
• Phases of Wound Healing:
1️⃣ Inflammatory Phase:
• Key players: Neutrophils, macrophages 🦠
• Events: Clot formation, removal of dead tissue, and release of growth factors 🔬
2️⃣ Proliferative Phase:
• Formation of granulation tissue, angiogenesis, and epithelialization 🧬
3️⃣ Remodeling Phase (Maturation):
• Collagen deposition, wound contraction, and scar formation 🏥
• Types of Wound Healing:
• Primary Intention: Healing of clean, incised wounds with minimal scarring ✂️
• Secondary Intention: Healing of larger wounds with granulation tissue and significant scarring 💉
• Factors Influencing Wound Healing:
• Local factors: Infection, blood supply, and wound size 🚑
• Systemic factors: Diabetes, nutritional status, and medications 🌡️
• Pathological Outcomes:
• Delayed healing, hypertrophic scars, keloids, and contractures
• Clinical Relevance and Management Strategies:
• Role of dressings, antibiotics, and advanced therapies like skin grafts
This video provides a detailed overview of the phases and factors involved in wound healing, making it ideal for NEET PG preparation and first-year MBBS pathology!
