Management of Accidental Formalin Ingestion

Initial Assessment and Management

The American College of Emergency Physicians recommends immediately assessing airway, breathing, and circulation, and contacting a Poison Control Center to evaluate systemic toxicity of the ingested agent, as formalin ingestion can cause rapid deterioration with metabolic acidosis and multiorgan dysfunction 3
The World Journal of Emergency Surgery suggests performing laboratory evaluation including complete blood count, serum electrolytes, liver function tests, arterial blood gases, and renal function tests to assess the severity of poisoning 1, 3

The Hepatology society recommends considering activated charcoal (standard dose 1g/kg orally) to limit absorption if presentation is within 1 hour of ingestion 3
The World Journal of Emergency Surgery advises avoiding gastric lavage if corrosive injury is suspected, as it may increase risk of perforation, and considering early endoscopy to assess the extent of corrosive injury to the upper gastrointestinal tract 1, 2

The World Journal of Emergency Surgery recommends obtaining surgical consultation early if there are signs of perforation or extensive necrosis, as up to 1-3% of patients with corrosive ingestions require surgery due to complications such as perforation, mediastinitis, or severe bleeding 1, 2
Esophagotomy with primary closure may be considered in cases with limited contamination 1

The American Thoracic Society recommends psychiatric evaluation for intentional ingestions 4

The World Journal of Emergency Surgery warns against delaying endoscopic evaluation, which can lead to missed opportunities for early intervention, and underestimating the severity of injury, as initial symptoms may not correlate with the extent of damage 1, 2
Failing to monitor for delayed complications such as stricture formation or perforation is also a common pitfall 1
