Which of the following is an early intubation indication in burn patients?

• A. Extensive deep facial burns
• B. Burns in mouth
• C. Signs of airway obstruction
• D. Total BSA 40%+

Answer: (C)

Airway edema from burn injuries can progress rapidly, so securing the airway early when trouble is indicated is key. The clearest signal that an airway needs immediate protection is signs that the airway is becoming obstructed. If a patient exhibits stridor, significant hoarseness or voice changes, use of accessory muscles, or other signs of evolving obstruction, intubation should be performed promptly while the airway is still manageable. This proactive approach prevents a potential airway collapse and hypoxia that can occur if you wait for full obstruction to develop.

While extensive facial burns or burns inside the mouth raise concern for possible airway swelling and necessitate careful monitoring and early planning, they do not by themselves prove that obstruction is present. A very large burn surface area indicates severity but does not directly indicate airway status. The key factor guiding early intubation is actual or imminent airway obstruction.
