Images 1 & 2 (Palm view - same photo, duplicated)

• Localized tense swelling at the base of the fingers (proximal finger region/web space), giving a bulbous, distended appearance
• A large bulla (blister) - a dome-shaped, semi-translucent, fluid-filled elevation on the uppermost visible finger. The overlying skin is stretched thin and taut
• Shiny, glistening skin - consistent with a topical ointment or cream having been applied
• A small white speck in the web space, possibly macerated skin, a tiny pustule, or cream residue
• Erythema/dusky discoloration at the margins of the swelling, suggesting underlying inflammation

Image 3 (Dorsal view - back of hand)

• Deep purple/dark brown/bluish-black band-like discoloration on the proximal phalanges (base segments) of the middle, index, and ring fingers
• The middle finger is most severely affected - a wide, semi-circumferential dark band covers much of the proximal phalanx and extends over the PIP joint
• Localized swelling most prominent at the middle finger in the area of darkest discoloration
• Skin surface remains intact - no open wounds or blisters visible from this side
• Skin texture shows normal aging (fine wrinkles, prominent veins)

Overall Impression

• Trauma/crush injury with bruising and blister formation
• Severe insect/animal bite reaction with local tissue reaction
• Infection (e.g., cellulitis, abscess, or even necrotizing process - the dark discoloration warrants attention)
• Gout flare with overlying skin changes
• Vascular compromise to the fingers

Important: The dark discoloration (especially the near-black/purple banding on the finger joints) combined with blistering and swelling should be evaluated by a doctor promptly. If there is also pain, warmth, spreading redness, or numbness/coldness in the fingers, this is potentially urgent.

Hot Oil Splash - Thermal Burn Assessment & Management

Burn Depth Classification

• Tense fluid-filled bullae (blisters) - classic finding
• Surrounding erythema and edema
• Skin still intact beneath the blister
• Hot oil causes this pattern because it adheres to skin and transfers heat efficiently

• Deep second-degree: mottled white/pink, reduced sensation, slower healing (>3 weeks)
• Third-degree: leathery, insensate, requires grafting
• The dark discoloration over joints is concerning - hands are a high-priority body part

Why This Burn Matters Clinically

"Burns involving the face, hands, feet, genitalia, perineum, or major joints" should be considered for referral to a burn center.

Immediate First Aid (if not already done)

1. Cool the burn - run cool (not cold/iced) water over the area for 10-20 minutes. This is most effective within the first 3 hours of the burn.
2. Do NOT apply butter, toothpaste, or any home remedies - these trap heat and increase infection risk.
3. Do NOT pop the blisters - intact blisters protect the wound from infection.
4. Remove rings/jewelry from the affected hand immediately - swelling will worsen and they can act as a tourniquet.
5. Cover loosely with a clean, non-fluffy dressing.

Blister Management

• Intact blisters = natural biological dressing, keep them intact if possible
• Large/tense blisters over joints (like those seen here) may need aspiration or debridement at the ED to allow proper wound assessment and prevent rupture under pressure
• Once debrided, apply an antibiotic ointment (silver sulfadiazine or bacitracin) and a non-adherent dressing

Hand Dressing Technique

"Separate the fingers with fluff in the web spaces and enclose the entire hand in a position of function... [failure to do so results in] second-degree skin loss because of maceration of normal skin between the fingers."

• Wrap each finger individually
• Place gauze/fluff between all fingers in web spaces
• Dress the hand in the position of function (wrist slightly extended, fingers slightly flexed)
• A splint may be needed if the wrist is involved

Pain Management

"Inadequate analgesia is probably the most common ED error in the treatment of burn injuries." - Roberts & Hedges'

• Oral ibuprofen or paracetamol for mild-moderate pain
• Parenteral opioids (fentanyl 1-2 mcg/kg or morphine 0.1-0.2 mg/kg) for dressing changes/debridement

Topical Agents

• Silver sulfadiazine 1% cream - standard, broad antimicrobial coverage
• Bacitracin or mupirocin - alternative, less eschar formation, easier dressing changes
• Honey-based dressings or modern dressings (Mepitel, Aquacel Ag) are used in burn centers

Should This Person Go to Hospital?

1. Hands are a burn center referral criterion by ABA guidelines
2. The dark discoloration on the dorsum (Image 3) needs clinical assessment to rule out deep partial or full-thickness injury
3. Depth of oil burns can be underestimated in the first 24-48 hours - the wound may look superficial initially and declare itself deeper at 48-72 hours
4. If joints are involved (fingers), there is risk of contracture formation without proper splinting and physiotherapy

Oral Antibiotics for This Burn - No, Not Routinely

"Antibiotic prophylaxis is not appropriate and evidence does not support its use."

• Fitzpatrick's Dermatology

"Systemic antibiotic prophylaxis is not advised as it often leads to bacterial antimicrobial resistance. Instead, treatment of burn wound infections relies on the use of local antimicrobial agents."

• Fischer's Mastery of Surgery

What to Do Instead of Oral Antibiotics

• Apply silver sulfadiazine cream or silver-impregnated dressings at the burn site - this provides a reliable antimicrobial barrier
• Daily or every-other-day dressing changes
• Keep the wound dressed and not exposed to the environment
• Elevate the hand - tissue edema is itself a nidus for infection, and elevation reduces it
• Avoid swimming (rivers, oceans, hot tubs) - risk of Pseudomonas

When DO Oral Antibiotics Become Necessary?

Which Antibiotic If Infection Does Occur?

• First 7-10 days - if infection develops, it's usually Staphylococcus (normal flora). A first-generation cephalosporin (e.g., cefalexin) responds well.
• After day 10 - Gram-negative organisms become more likely. Ciprofloxacin with wound culture is recommended.
