Wounds

Definition: Disruption of the continuity of skin, mucous membrane or soft tissue caused by physical, chemical, or biological insult.
Causes:
- Mechanical: Abrasions, cuts, stab wounds, insect bites, or gunshot wounds
- Chemical: Burns, frostbite
- Electrical: Electrical injury
Classification:
- Closed (blunt): e.g. motor vehicle accidents, falls
- Open (penetrating):
  - Accidental: gunshot, cuts, stab wounds, bites.
  - Surgical: caused by sharp instruments.
Intention:
- Intentional: planned treatment
- Unintentional: traumatic/accidental
Severity
- Superficial
- Deep
Onset:
- Acute: normal/timely healing
- Chronic: fails to go through the normal stages of healing, no timely progress in healing
Types of Open Wounds
- Abrasions: Scraping away superficial layers of skin
- Penetrating wounds: Pressure by sharp objects (e.g., nail, needle).
- Incised wounds: A neat cut wound (e.g., surgical scalpel)
- Lacerations: Severe violence with blunt objects (e.g., road traffic accident)
- Stab wounds: Caused by sharp, flat objects (e.g., knife)
- Bites: Caused by animal or human teeth
- Stings: Caused by insects, spiders, or scorpions
- Cut wounds: Caused by sharp objects with minimal blunt force
Types of Closed Wounds
- Crushed wounds: Extreme pressure smashing skin and underlying tissue
- Contusions (bruises): Intradermal bleeding from minor capillaries with interstitial tracking.
Important characteristics of lacerated wounds: Severely traumatized, devascularized, irregular in shape, usually contaminated, risk of high infection

Wound Healing

Definition: Physiological process where the body repairs damaged tissue to restore form and function.
Components: Wound contraction, granulation tissue formation, epithelialization
Hemostasis & Coagulation: Blood clot formation
Inflammation: Characterized by redness, heat, pain, and swelling
Proliferative Phase: Cellular proliferation, cellular migration, angiogenesis (formation of new blood vessels). Synthesis of collagen
Remodeling Phase: Capillary regression. Collagen synthesis. scar formation.

Wound Complications

Wound Failure (Dehiscence): Wound gaps after closure.
Stretching of the scar: In wounds with delayed healing due to infection.
Hypertrophied scar: More cellular, vascular scar.
Keloid formation: Extreme overgrowth of scar tissue beyond the original wound.
Contracture: Scar tissue shortening, resulting in joint deformity.
Surgical Site Infection: Infection at the site of the surgery.
Injury and ischemia (reduced blood supply in tissues), lymphedema/hematoma/seroma (fluid buildup and abnormal accumulation of blood): Post surgical complications.

Wound Management

General: Follow ATLS protocol, wound assessment, tetanus prophylaxis.
In the Theatre:
- Wound cleansing
- Wound debridement
- Ligature/electrocautery for bleeding points
- Proper wound dressing (e.g., non-allergic, allow gas exchange)
Sutures:
- Primary sutures: applied at the time of injury
- Delayed primary sutures: applied 5-7 days later to doubtful wounds
- Secondary sutures: applied to clean wounds after granulation.
Reconstruction: replacing lost skin or tissues.
Additional Management of Keloids/Hypertrophic Scars: pharmacologic therapy, pressure, lasers, radiation therapy, compression garments, surgical excision
