A 35 year old man is brought to the casualty after being rescued from a house fire. 100% oxygen is administered by nonrebreather mask, and his oxygen saturation is 99% by pulse oximetry. Pulse rate is 115/min, respiration rate is 30/min, and blood pressure is 120/70 mm Hg. There is no stridor, no use of the accessory muscles of respiration, and GCS is 15. There are facial burns as well as singed nasal hairs and soot in the posterior oropharynx. Lungs are clear with good air entry bilaterally.
Which one of the following is most correct about this patient’s condition?
A. The pressure of facial burns reliably predicts the presence of airway injury.
B. Direct laryngoscopy or bronchoscopy should be performed for airway injury.
C. This patient is at low risk for delayed 2 days postinhalation injury to the lower airways.
D. Dexamethasone should be empirically administered.
Answer : B (Direct laryngoscopy or bronchoscopy should be performed for airway injury)
