Study Notes
Burns
- First degree: Affects only the epidermis (outermost skin layer).
- Signs: Redness and swelling of the skin.
- Second degree: Epidermis and superficial dermis are affected.
- Signs: Skin blisters.
- Third degree: Destroys the dermis and deeper nerve tissue.
- Signs: Charring (black skin) indicates extensive damage; loss of sensation due to nerve involvement.
Symptoms of Burns
- Pain (lack of pain): Indicates deeper damage (typically third-degree burns).
- Loss of sensation: Can be indicative of nerve damage.
- Visual impairment (VA loss): Possible internal damage.
Thermal Burns (types)
- Chemical burns: Caused by acids or alkalis (lye, cement, ammonia, etc).
- Thermal burns: Caused by heat, such as flames, hot liquids or steam.
Treatment of Burns
- Treatment plan: Cold compresses immediately after injury to help reduce further damage.
- Bacterial prophylaxis: (e.g., Bacitracin, Polymyxin B) to prevent infection.
- No fluorinated steroids: Use topical antifungals such as Polymyxin B or other similar topical agents.
Blunt Trauma
- Signs: Ecchymosis (bruising), edema (swelling), sub-conjunctival hemorrhages
- Symptoms: Discomfort, tenderness, and pain
- Critical symptoms: Decreased visual acuity (decreased VA), double vision (diplopia).
Foreign Bodies on Lid Tarsus
- Signs: Conjunctival injection, eyelid edema, "Corneal tracking", tearing.
- Management: Irrigation, wet cotton swab to remove foreign body, prophylactic antibiotic (e.g., Bacitracin, Bacitracin/Polymyxin B).
Eyelid Lacerations
- Signs: Superficial or deep lacerations
- Symptoms: Mild periorbital pain and tearing.
- Management: Clean wounds using hydrogen peroxide or Zephiran, and apply antibiotic ointment, dressing.
