🩹✨ FOUR PHASES OF WOUND HEALING — EVERY NURSE MUST KNOW! 👩⚕️
Have you ever wondered how the human body repairs damaged tissue after an injury or surgery? 🤔
Wound healing is a natural process that occurs in 4 overlapping phases. Understanding these stages helps nurses assess wounds, identify complications and support faster healing.
📚 4 PHASES OF WOUND HEALING
🩸 1️⃣ HAEMOSTASIS — STOP THE BLEEDING
⏰ Immediately after injury
✅ Blood vessels constrict.
✅ Platelets form a plug.
✅ Fibrin forms a blood clot.
🟡 2️⃣ INFLAMMATION — CLEAN THE WOUND
⏰ Approximately days 1–4
✅ White blood cells remove bacteria and debris.
✅ Mild redness, warmth and swelling may occur.
✅ The wound prepares for tissue repair.
🌱 3️⃣ PROLIFERATION — BUILD NEW TISSUE
⏰ Approximately days 4–21
✅ Granulation tissue develops.
✅ New blood vessels form.
✅ Collagen is produced.
✅ New skin cells cover the wound.
💙 4️⃣ REMODELLING — STRENGTHEN THE TISSUE
⏰ From approximately week 3; may continue for months to years
✅ Collagen fibres reorganise.
✅ Scar tissue becomes stronger.
✅ The scar gradually matures.

⚠️ FACTORS THAT DELAY WOUND HEALING
❌ Infection
❌ Poor blood circulation
❌ Uncontrolled diabetes
❌ Malnutrition
❌ Smoking
❌ Prolonged pressure or friction
🚨 IMPORTANT NURSING TIP:
Increasing wound pain, spreading redness, purulent discharge or fever may indicate infection and require prompt assessment.
📌 Remember: Wound healing phases overlap, and healing times vary between patients.
