What is the appropriate emergency department management for a patient with a nasal burn from an outdoor propane grill a few days ago who now has difficulty breathing through the left nostril?

Emergency Department Management of Nasal Burn with Unilateral Breathing Difficulty

For a patient presenting several days post-nasal burn with unilateral nasal obstruction, the immediate ED priority is direct nasal examination with adequate lighting and suction to rule out septal hematoma, which requires urgent drainage to prevent septal necrosis and permanent deformity.

Critical Initial Assessment

The two-pronged approach focuses on:

1. Airway evaluation for delayed complications
2. Direct nasal examination for structural injury

Airway Assessment

While this patient is several days out from injury and breathing difficulty is isolated to one nostril (suggesting localized rather than systemic airway compromise), you must still evaluate for:

• Signs of inhalation injury: facial burns, singed nasal hairs, soot around nose/mouth, hoarseness, or stridor 1
• Progressive airway edema: Though typically manifests within 24-48 hours, delayed presentations can occur
• Respiratory distress: shortness of breath, stridor, or increased work of breathing

If any signs of inhalation injury or respiratory compromise are present, activate immediate airway management protocols. However, given the delayed presentation (several days) with isolated unilateral nasal obstruction, systemic airway compromise is unlikely 2, 3.

Direct Nasal Examination - The Critical Step

Perform immediate nasal examination with:

• Good lighting (headlamp or otoscope)
• Nasal speculum
• Suction available

What You're Looking For:

Septal hematoma - This is the disaster you cannot miss 4:

• Appears as boggy, bluish swelling of the nasal septum
• Bilateral or unilateral
• Obstructs nasal airway
• Requires immediate drainage to prevent:
  • Septal necrosis (within 3-5 days)
  • Saddle nose deformity
  • Septal perforation
  • Abscess formation

Other findings to assess:

• Mucosal burns (erythema, blistering, necrosis)
• Nasal turbinate edema
• Crusting or eschar formation
• Septal deviation or fracture
• Active bleeding

ED Management Algorithm

If Septal Hematoma Present:

1. Immediate ENT consultation for incision and drainage
2. Do not delay - this is time-sensitive
3. Post-drainage: nasal packing, antibiotics, close follow-up

If No Septal Hematoma:

For mucosal burn with edema causing obstruction:

1. Topical decongestants: Oxymetazoline spray to reduce mucosal edema (short-term use only, 3-5 days maximum)

2. Pain management: Over-the-counter NSAIDs or acetaminophen 1

3. Nasal care:

   • Saline irrigation to remove crusting and debris
   • Petroleum-based ointment to prevent crusting
   • Humidification

4. Monitor for infection: Prophylactic antibiotics generally not indicated unless signs of infection present

5. ENT follow-up within 24-48 hours for:

   • Reassessment of healing
   • Evaluation for delayed complications
   • Management of potential scarring/stenosis

Red Flags Requiring Admission or Urgent Intervention

• Septal hematoma (immediate drainage required)
• Signs of inhalation injury
• Bilateral nasal obstruction with respiratory compromise
• Evidence of infection (fever, purulent drainage, cellulitis)
• Significant facial burns requiring specialized burn care
• Inability to maintain oral intake due to pain

Common Pitfalls to Avoid

Missing septal hematoma is the most critical error - it appears innocuous but leads to permanent deformity if not drained urgently 4. The key is that it develops over 24-72 hours post-injury, so the "few days ago" timeline fits perfectly for this complication.

Assuming unilateral obstruction is benign - while less concerning than bilateral obstruction, it still requires thorough examination to rule out structural injury.

Delaying ENT referral - even without septal hematoma, nasal burns can lead to scarring and stenosis. Early ENT involvement optimizes long-term outcomes 5.

Disposition

• Discharge home if: no septal hematoma, no airway concerns, adequate pain control, reliable for follow-up
• ENT follow-up: 24-48 hours
• Return precautions: worsening breathing difficulty, fever, increased pain, bleeding

The unilateral nature of symptoms several days post-injury suggests localized mucosal injury rather than critical airway compromise, but the examination cannot be skipped - septal hematoma is the time-sensitive emergency that determines outcome 4.
