Toxicology Summary of the Ingested Agents

Emergency Management

STEP 1 - Immediate Action (Pre-hospital / First Contact)

• Do NOT induce vomiting - camphor can cause abrupt-onset seizures; vomiting risks aspiration and sudden neurological deterioration.
• Do NOT give syrup of ipecac - same reason.
• Call Poison Control immediately (India: 1800-11-6117 or nearest Poison Control Centre).
• Rush to the nearest Emergency Department - do not wait for symptoms. Seizures can begin within 5-30 minutes of ingestion.

STEP 2 - Initial Assessment in ED (ABCs)

• GCS assessment
• Look for postictal state, lethargy, agitation, or twitching - these are early warning signs of camphor-induced seizures.
• Camphor smell on breath or vomitus is a clinical clue.

STEP 3 - Decontamination

• May be considered if the child presents within 60 minutes of ingestion and has NOT yet seized.
• Must be done with airway protection in place (cuffed ET tube if consciousness is impaired).
• Not universally recommended; use clinical judgment.

• Controversial - camphor is rapidly absorbed and widely distributed.
• If given, it must be within 1 hour of ingestion, and only in a child with a protected, patent airway.
• Administer: 1 g/kg (approximately 10 g for a 10 kg child) as a single dose.
• The PMC review on essential oil ingestion notes its role is not well-established for these oils.

• Milk, oils, or fat-rich drinks (these enhance camphor absorption).
• Cathartics or enemas.

STEP 4 - Monitoring and Observation

• Seizures (onset typically within 30-90 minutes, but can be delayed up to several hours)
• Vomiting
• Altered consciousness / lethargy / coma
• Respiratory depression
• SpO2, HR, RR, BP every 15 minutes initially

• Blood glucose (hypoglycemia can compound CNS effects)
• Serum electrolytes, BMP
• ABG if respiratory distress
• LFTs (eucalyptol is hepatotoxic in large doses)
• ECG

STEP 5 - Seizure Management

• Diazepam 0.2-0.3 mg/kg IV (up to 0.5 mg/kg) - repeat every 5 minutes if needed, maximum 3 doses.
• Alternatively: Lorazepam 0.05-0.1 mg/kg IV.

• Phenobarbital 15-20 mg/kg IV (slow infusion over 20 minutes).
• Levetiracetam 20-60 mg/kg IV - used successfully in a 1-year-old camphor toxicity case report (BMC Pediatrics, 2025).

• Midazolam infusion or Propofol (in ICU setting with ventilatory support).
• Intubation and mechanical ventilation if seizures are refractory.

STEP 6 - ICU Admission Criteria

• Any seizure has occurred
• Altered consciousness (GCS < 15)
• Respiratory compromise
• Status epilepticus
• Age < 2 years (higher vulnerability, lower threshold)

• PICU admission for minimum 48 hours after seizure onset
• Hourly vital sign monitoring
• Levetiracetam (10 mg/kg/day IV) for ongoing seizure prophylaxis
• PRN diazepam 0.2 mg/kg IV for breakthrough seizures

STEP 7 - Enhanced Elimination

• No specific antidote exists for camphor, eucalyptol, menthol, or terpineol.
• Forced diuresis, hemodialysis, and hemoperfusion are generally not recommended - these compounds are highly lipophilic and widely distributed in tissues; elimination enhancement provides minimal benefit.

STEP 8 - Supportive Care

• Maintain euglycemia (dextrose-containing IV fluids if needed in infants)
• Correct electrolyte imbalances
• Gastric protection: Omeprazole 1 mg/kg/day IV (as used in the 2025 PICU case)
• Maintain temperature (these agents can cause both hypo- and hyperthermia)
• Avoid sedatives that compound respiratory depression unless intubated

Discharge Criteria

• Asymptomatic for at least 4-6 hours post-ingestion
• Normal neurological exam
• Normal vital signs
• Caretaker is reliable and aware of warning signs for return

Key takeaway: Even a single Easibreathe capsule is potentially dangerous for a 1-year-old. Camphor (25 mg) and eucalyptol (125 mg) together represent a real seizure risk in this age group. This is a medical emergency requiring immediate ED referral and close neurological monitoring. No vomiting induction. Seizure control with benzodiazepines is the cornerstone of treatment.

Giving Water After Easibreathe / Camphor-Eucalyptol Ingestion

Why Water is NOT Recommended Orally

1. Seizure risk is the overriding concern - Camphor can cause sudden onset seizures within minutes. Giving anything orally (including water) risks aspiration if a seizure occurs while the child is drinking.
2. Water does not dilute or neutralize these volatile aromatic compounds meaningfully. Camphor, eucalyptol, menthol, and terpineol are lipophilic - water has no binding or inactivating effect on them.
3. It may increase absorption speed by facilitating gastric emptying and mucosal contact.
4. Milk and fatty drinks are specifically contraindicated (they enhance camphor absorption) - water is safer than milk, but still not indicated orally.

What About IV Fluids?

• Establish IV access early
• Use dextrose-containing fluids (D5 0.45% NaCl or D5NS) to maintain euglycemia, which is especially important in a 1-year-old
• IV route avoids aspiration risk entirely

Exceptions / When Small Sips May Be Acceptable

Bottom Line

In a 1-year-old with camphor/eucalyptol ingestion - keep the child NPO (nothing by mouth). Do not give water, milk, or any oral fluid. Establish IV access and give fluids intravenously. The primary reason is the unpredictable, rapid-onset seizure risk from camphor which makes any oral intake a serious aspiration hazard.
