Study Notes

Wounds: Definition and Types

A wound is a break in the continuity of skin, tissues, or mucous membranes due to physical injury.
Types of wounds:
- Intentional wounds (e.g., surgical incisions, stab wounds, gunshot wounds).
- Unintentional wounds (accidental injuries like cuts).

Classification of Wounds

Classification based on:
- Mechanism of injury
- Degree of contamination

Mechanism of Injury

Open wounds: Break in skin or mucous membranes caused by sharp objects (e.g., surgical wounds, lacerations).
Closed wounds: Tissue damage without skin breakage (e.g., contusions, post-operative infections).
Colonized wounds: Presence of multiple microorganisms (e.g., pressure sores).

Types of Open Wounds

Incised wounds (incisions): Smooth, even edges, can be aseptic or infected, caused intentionally or accidentally.
Contused wounds (contusions): Closed wounds from blunt force, causing bruising and pain.
Abrasions: Open wounds from friction, confined to the epidermis, treated by irrigation.
Punctured wounds (stab wounds): Open wounds from sharp objects, require surgical exploration.
Lacerations: Open wounds with jagged edges, often from animal bites or machinery.
Penetrating wounds: Sharp instruments penetrate deeply, often accidental.
Perforating wounds: Open wounds exposing body cavities, often from gunshots.

Wound Healing Phases

Inflammatory Phase: Initial healing response characterized by swelling, heat, pain, and redness due to white blood cells and growth factors.
Proliferative Phase: New tissue formation involving collagen, granulation tissue, and vascular networks; optimal healing occurs with maintained moisture.
Maturation Phase: Collagen remodeling and wound closure; excess cells removed through apoptosis.

Symptoms of Wound Infection

Local symptoms: Redness, heat, swelling, pain, loss of function.
General symptoms: Elevation in temperature, increased pulse and respiration rates, malaise, anorexia, nausea, headache, chills.

Factors Affecting Wound Healing

Reducing factors:
- Age and malnutrition slow healing.
- Obesity leads to inadequate blood flow.
- Conditions like diabetes and smoking impair recovery.
Improving factors:
- Good overall health, young age, balanced diet, proper antibiotic use, and sterile technique enhance healing.

Complications of Wound Healing

Possible complications include:
- Hemorrhage and infection.
- Abscess formation.
- Dehiscence: separation of wound edges.
- Evisceration: protrusion of internal organs.
- Fistulas and keloids.
- Contractures of tissue.
