Management of Hydrochloric Acid Ingestion

Initial Emergency Management

The American Heart Association recommends immediately activating emergency medical services (EMS) if the patient shows any signs of life-threatening conditions such as respiratory distress, vomiting, or altered mental status 1
Contact the Poison Help hotline for expert guidance on management of hydrochloric acid ingestion 1
Remove any remaining acid from the oral cavity and remove contaminated clothing around the mouth and face area to prevent further exposure 3

Do not administer water or milk for dilution without specific medical advice, as there is insufficient evidence supporting this practice and possible adverse effects include emesis and aspiration 1, 2, 3
Do not administer activated charcoal as it is ineffective for caustic substances and may obscure subsequent endoscopic evaluation 1, 3
Do not administer syrup of ipecac as it can cause intractable emesis and delay care in an advanced medical facility 1

Conduct emergency contrast-enhanced CT examination 3-6 hours after ingestion to detect transmural injuries 3
Perform upper gastrointestinal endoscopy within 12-48 hours to determine prognosis and guide management 3
Laboratory evaluation should include complete blood count, electrolytes, liver function tests, pH, and serum lactate to identify potential systemic effects 3

For skin or eye exposure to acid, immediately irrigate the affected area with copious amounts of water 1
For severe metabolic acidosis from acid ingestion, sodium bicarbonate may be administered (1-2 mEq/kg IV) after effective ventilation has been established 4
For patients with evidence of transmural necrosis, emergency surgery should be considered as it may be lifesaving 3
For patients without full-thickness necrosis, non-operative management with close clinical monitoring may be offered 3

Long-term complications may include stricture formation requiring endoscopic dilation, though this should be avoided within 3 weeks of initial ingestion due to higher risk of complications 3

Clinical symptoms do not always correlate with the extent of gastrointestinal damage, with absence of pain and oral lesions not ruling out serious injuries 3
Acids cause coagulative necrosis forming an eschar that may limit penetration, but tend to cause more severe gastric injury than esophageal injury due to rapid transit through the esophagus and pooling in the stomach 3
The physical form of the ingested substance affects the pattern of injury, with liquids causing burns of the esophagus and stomach 3
