Background
- Hydrogen fluoride (HF) is a byproduct of standard fire suppression systems.[1]
Clinical Features
- Exposure to HF may result in rapidly progressive or fatal respiratory failure despite minimal external evidence of injury. [2]
- Symptoms include shortness of breath, cough, or hypoxia; there must be a high level of suspicion for HF inhalation.[3]
Differential Diagnosis
Burns
- Smoke inhalation injury (airway compromise)
- Chemical injury
- Acrolein
- Hydrochloric acid
- Tuolene diisocyanate
- Nitrogen dioxide
- Systemic chemical injury
- Specific types of burns
- Associated toxicities
Evaluation
Management
- Treatment is supportive.
- If hypocalcemia is present, administer nebulized calcium gluconate (1.5 ml of 10% calcium gluconate in 4.5 ml water) q4hr until normalization of serum calcium levels. [4]
- In the absence of significant burns, consider steroids if symptoms do not improve. [5]
