Management of Epoxy or Polyester Resin Ingestion (100 mL)
Immediately contact Poison Control (1-800-222-1222 in the US) and do NOT induce vomiting, administer activated charcoal, or give anything by mouth unless specifically directed by poison control or emergency medical personnel. 1
Immediate Actions
Do NOT Perform These Interventions
- Do not induce emesis - Vomiting is contraindicated as it risks aspiration and esophageal injury 1
- Do not administer activated charcoal unless specifically directed by poison control, as there is no evidence of benefit and potential for harm 1
- Do not give water or milk - Dilution has not been shown to provide clinical benefit and may cause emesis and aspiration 1
- Do not administer ipecac - This is contraindicated for all toxic ingestions 1
Essential First Steps
Assess for life-threatening symptoms immediately: Look for altered mental status (sleepiness, agitation), seizures, respiratory distress (tachypnea, difficulty breathing), vomiting, or signs of airway compromise 1
Activate EMS immediately if any life-threatening symptoms are present 1
Contact Poison Control (1-800-222-1222) with the following information ready:
- Exact product name and composition (epoxy vs polyester resin)
- Volume ingested (100 mL)
- Time of ingestion
- Patient symptoms 1
Clinical Considerations
Potential Complications to Monitor
Epoxy and polyester resins can cause:
- Gastrointestinal obstruction: Some adhesive products (particularly polyurethane-based) can expand 4-8 times their original volume within minutes to hours, forming obstructive masses 2
- Mucosal injury: Direct caustic effects on esophageal and gastric mucosa, potentially leading to hemorrhage, ulceration, or perforation 2, 3
- Systemic toxicity: Components like epichlorohydrin, bisphenol A, and amine hardeners can cause both immediate and delayed toxic effects 4
Timeline for Symptom Development
- Clinical signs typically develop within 12 hours of ingestion 2
- Radiographic evidence of obstruction may appear as early as 4-6 hours post-ingestion 2
- Watch for: anorexia, lethargy, vomiting, tachypnea, abdominal distention, and abdominal pain 2
Diagnostic Approach
Imaging Studies
Obtain abdominal radiographs if the patient develops symptoms or if a significant volume was ingested, as the foreign body mass may be visible within 4-6 hours 2
Consider endoscopy within 24 hours for:
- Intentional ingestions
- Symptomatic patients with oral burns, dysphagia, or abdominal pain
- Substantial volume ingestions (100 mL qualifies as substantial) 3, 5, 6
Endoscopy should be performed within 24 hours to grade injury severity while avoiding the increased perforation risk that occurs later 3
Treatment Strategy
Supportive Care Only
The management is entirely supportive with close monitoring:
- NPO (nothing by mouth) until injury severity is assessed
- IV fluid resuscitation if needed
- Monitor vital signs and respiratory status
- Serial abdominal examinations
Surgical Consultation
Obtain immediate surgical consultation if:
- Signs of perforation develop (peritonitis, free air on imaging)
- Evidence of complete obstruction
- Endoscopy reveals deep or circumferential burns 2, 3, 6
Surgical removal may be required if a solid foreign body mass forms, as this is the safest and most effective therapy 2
Common Pitfalls to Avoid
- Attempting home decontamination - This delays definitive care and may worsen outcomes
- Assuming absence of oral burns means no esophageal injury - Esophageal injury can occur without visible oral burns 6
- Delaying endoscopy beyond 24 hours - This increases perforation risk 3
- Administering liquids to "dilute" the poison - This is ineffective and may promote expansion of adhesive products 2
Disposition
- Admit for observation all patients with 100 mL ingestion given the substantial volume
- Minimum 12-24 hour observation period to monitor for delayed symptom development
- Discharge only if completely asymptomatic after observation period AND endoscopy (if performed) shows no significant injury
