A 5-year-old child ingested an unknown quantity of caustic drain cleaner. On arrival, the child is conscious, drooling, and complaining of severe oral and throat pain. The child's airway appears patent but is swelling. What is the most important immediate action for the paramedic?
- AAdminister milk or water to dilute the substance
- BInduce vomiting to remove the substance
- CAdminister activated charcoal orally
- DRapidly secure the airway with intubation if swelling progresses
Show answer & explanationAnswer & explanation
Correct answer: D. Rapidly secure the airway with intubation if swelling progresses
Ingestion of caustic substances causes severe burns to the oral cavity, pharynx, and esophagus, leading to rapid swelling and potential airway compromise. The most immediate and critical concern is securing the airway before it becomes completely obstructed due to swelling. Activated charcoal is ineffective for caustics, inducing vomiting is contraindicated, and dilution with milk/water is secondary to airway management and should be done cautiously if at all.
Why the other options are wrong
- A. While dilution with small amounts of water or milk may be considered in some cases, it is secondary to airway management and should not delay definitive airway control if swelling is present.
- B. Inducing vomiting is contraindicated in caustic ingestions as it can cause re-exposure and further esophageal damage.
- C. Activated charcoal is ineffective for caustic ingestions and can hinder endoscopic evaluation.
Caustic Ingestion Management
Emergency care for ingestion of strong acids or alkalis, primarily focusing on airway protection and avoiding interventions that could worsen injury.
- Airway compromise is the leading cause of early mortality.
- Do NOT induce vomiting or administer activated charcoal.
- Monitor for progressive swelling of the airway and prepare for intubation.
