Wounds, Healing & Surgical Infection

Relate tissue injury and healing to wound assessment, infection prevention and timely source control.

FULL CHAPTER EXPLANATION

Deep Learning — Module 05

Connect anatomy and symptoms to surgical differentials, investigations, urgent priorities and recovery.

01

Phases of healing

Hemostasis limits bleeding, inflammation clears damaged tissue, proliferation builds granulation tissue and epithelium, and remodeling reorganizes collagen. These phases overlap rather than occurring as isolated calendar events. Adequate perfusion, nutrition and appropriate mechanical support help healing; smoking, diabetes, infection and some medicines may impair it. A healed skin surface does not mean the deeper wound has immediately recovered its original strength.

02

Assess the whole wound

Describe site, depth, edges, tissue viability, contamination, discharge and surrounding skin, together with pain and systemic observations. Explore the mechanism and timing of traumatic injury and the possibility of foreign material or deeper damage. Punctures, bites and devitalized tissue raise different concerns from a clean superficial cut. Evaluate tetanus protection under the local pathway and preserve important structures through trained assessment rather than blind probing.

03

Preventing infection

Hand hygiene, aseptic technique and appropriate skin preparation reduce contamination. Antibiotic prophylaxis is linked to the procedure and its timing; it does not compensate for poor technique or become indefinite treatment merely because a drain is present. Local policies account for likely organisms, allergy and resistance. If hair removal is necessary, methods that avoid skin injury are preferred over routine shaving with a razor.

04

Recognize infection and source needs

Increasing pain, erythema, warmth, swelling or purulent discharge may indicate infection, while fever or organ dysfunction suggests a wider response. Abscesses contain a collection that often requires drainage in addition to other care. Pain out of proportion, rapid progression, skin discoloration and systemic toxicity raise concern for necrotizing soft-tissue infection and urgent surgical assessment; a relatively small skin lesion can conceal deep destructive disease.

05

Dehiscence and follow-up

Wound separation can be superficial or involve deeper fascial failure. Sudden increased discharge, visible deeper tissue or evisceration needs immediate surgical help, protection of exposed tissue and avoidance of untrained manipulation. Explain dressing care, expected healing, warning signs and review arrangements in an accessible way. Chronic nonhealing wounds also require assessment of pressure, ischemia, neuropathy and possible malignancy rather than repeated dressings alone.

High-Yield Revision

  • Healing phases overlap and depend on perfusion.
  • An abscess may need drainage, not antibiotics alone.
  • Rapidly progressive pain and toxicity demand urgent review.

Common Exam & Concept Pitfalls

  • Surface appearance can underestimate deep infection.
  • Prophylaxis is not a substitute for aseptic technique.
