Patient handout

Pediatric toxic ingestions (acute)

PRODUCTION

1. Your condition

This handout is for pediatric toxic ingestions (acute). Your care team identified this based on: caregiver-reported or witnessed ingestion of medication/household substance in a child (aap/aapcc npds pathway).

Other reasons your team may use this plan: found-pill-bottle scenario in toddler with unknown amount missing — exploratory ingestion (aap/aapcc); altered mental status with toxidrome features (anticholinergic / opioid / sympathomimetic / sedative-hypnotic / cholinergic) in a child; unexplained hypoglycemia in a child — sulfonylurea or insulin ingestion until proven otherwise.

2. Your medications

Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.

MedicationStarting doseHowWhenWhat it does
activated charcoal1 g/kg PO/NG (max 50 g single dose)PO/NGsingle dose if within 1-2 h of ingestion + airway protectedAAP/AAPCC + AACT/EAPCCT position statements — single-dose charcoal effective only within 1-2 h; AVOID if airway not protected, caustic ingestion, or hydrocarbon (aspiration risk) (AACT/EAPCCT activated-charcoal position statement)
acetylcysteineIV Prescott protocol: 150 mg/kg over 1 h, then 50 mg/kg over 4 h, then 100 mg/kg over 16 h (total 300 mg/kg over 21 h)IVsingle 3-phase protocolHeard NEJM 2008 PMID 18635433 — IV N-acetylcysteine indicated when APAP level above 4-h treatment line on Rumack-Matthew nomogram; alternative PO 140 mg/kg load then 70 mg/kg q4h x 17 doses (Heard NEJM 2008)
deferoxamine15 mg/kg/h IV continuous infusionIVcontinuousACMT/AAPCC iron-toxicity guidance — chelate free iron in stage 2-4 toxicity; urine "vin rose" color indicates active chelation (AAP Red Book 2024-2027, Lexicomp Peds)
octreotide1-1.5 mcg/kg SC q6hSC/IVq6h x at least 24 hInhibits insulin release; mandatory adjunct to dextrose for sulfonylurea ingestion (children: low single-bite high-dose exposure to second-generation sulfonylureas like glyburide/glipizide); continue at least 24 h (Lexicomp Peds, ACMT toxic-ingestion guidance)
glucagon50 mcg/kg IV bolus then 0.05-0.15 mg/kg/h IV infusionIVbolus then continuousBypasses beta-adrenergic blockade via direct cAMP stimulation; first-line for symptomatic BB overdose; add HIE if refractory (ACMT position statement on BB toxicity; AAP Red Book 2024-2027)
insulin, regular, human1 U/kg IV bolus then 0.5-1 U/kg/h infusion with D10W titrated to euglycemiaIVbolus then continuousACMT/AAPCC HIE guidance for CCB/BB toxic shock — improves myocardial contractility; mandatory D10W co-infusion + frequent glucose monitoring + K+ monitoring (ACMT high-dose-insulin position statement)
sodium bicarbonate1-2 mEq/kg IV bolus then continuous infusion (150 mEq in 1 L D5W) titrated to serum pH 7.45-7.55 and urine pH 7.5-8.0IVbolus then continuous as neededReverses Na-channel blockade in TCA (QRS narrowing); enhances renal salicylate elimination via ion trapping; AVOID in pH >7.55 (ACMT TCA + salicylate guidance; AAP Red Book 2024-2027)
naloxone0.01-0.1 mg/kg IV/IM/IN/SC q2-3 min PRN; titrate to respiratory drive not full alertnessIV/IM/INq2-3 min PRN until respiratory drive restoredReverses opioid-induced respiratory depression; short half-life so anticipate re-narcotization (especially methadone, buprenorphine, fentanyl analogs) — infusion 2/3 of waking dose per h if needed (AAP Red Book 2024-2027, Lexicomp Peds)
methylene blue1-2 mg/kg IV over 5 minIVsingle dose; may repeat in 1 h if methemoglobin remains >30% or symptomaticReduces methemoglobin via NADPH-methemoglobin reductase; CONTRAINDICATED in G6PD deficiency (paradoxical hemolysis); offending agents include benzocaine, dapsone, nitrites, sulfonamides, local anesthetics (ACMT methemoglobinemia position statement; AAP Red Book 2024-2027)
hydroxocobalamin70 mg/kg IV over 15 minIVsingle dose; may repeat 70 mg/kg if persistent toxicityBinds cyanide to form cyanocobalamin (excreted renally); first-line in suspected smoke inhalation with cyanide features (lactate >8, altered MS, hypotension); avoid nitrites in concurrent CO toxicity (ACMT/AACT hydroxocobalamin position statement; AAP Red Book 2024-2027)
digoxin-specific antibody fragments (DigiFab)Per package insert: 1 vial neutralizes 0.5 mg digoxin; calculate from ingested dose, serum level, or empiric (10 vials acute / 6 vials chronic; pediatric per weight); reconstitute and infuse over 30 minIVsingle dose calculated per Fab vials neededDigiFab dose by package insert formula; non_pharm composite (no single RxCUI); indicated for life-threatening digoxin toxicity with K+ >5, ventricular arrhythmia, or shock (ACMT digoxin-toxicity guidance; AAP Red Book 2024-2027)
glucoseD25W 2-4 mL/kg IV for hypoglycemia <60 mg/dL infant or <70 mg/dL child; D10W maintenance infusion at GIR 6-8 mg/kg/minIVbolus then continuous for sulfonylureaReverses hypoglycemia from sulfonylurea / insulin / salicylate / ethanol / quinine; pair with octreotide for sulfonylurea (Lexicomp Peds; ACMT)
mannitol0.5-1 g/kg IV over 20 minIVsingle, may repeat in 30 minCerebral edema rescue when toxic ingestion causes acute liver failure with encephalopathy (e.g., severe APAP toxicity); cross-reference peds.reye-syndrome.v1 (AAP Red Book 2024-2027; Heard NEJM 2008)

Plan: Pediatric toxic ingestions — decontamination + per-toxin antidotes (Poison Control mandatory)

4. When to seek emergency care

Call 911 or go to the nearest emergency room right away if you have:

  • APAP level above 4-h treatment line on Rumack-Matthew nomogram OR staggered overdose OR time unknown with elevated LFT (Heard NEJM 2008 PMID 18635433)
  • TCA overdose with QRS >100 ms on 12-lead ECG (ACMT TCA-toxicity guidance)(life-threatening)
  • CCB or BB overdose with refractory shock not responding to first-line resuscitation (ACMT HIE position statement)(life-threatening)
  • Iron ingestion with shock, acidosis, hepatic dysfunction, OR iron level >500 mcg/dL — Smith stages 2-5 (ACMT iron-toxicity guidance)(life-threatening)
  • Methemoglobinemia with symptoms (cyanosis, altered MS, chest pain) OR methemoglobin >25-30% (ACMT methemoglobinemia position statement)
  • Opioid overdose with respiratory depression (RR below age-appropriate threshold OR apnea OR cyanosis) — pediatric exploratory ingestion or adolescent intentional (AAP Red Book 2024-2027)(life-threatening)
  • Sulfonylurea ingestion with hypoglycemia (any glipizide/glyburide exposure in toddler is potentially life-threatening) (Lexicomp Peds; ACMT)
  • Salicylate level >100 mg/dL (acute) OR >60 mg/dL with altered MS/acidosis OR any chronic salicylate with toxicity (ACMT salicylate position statement)(life-threatening)
  • Known cyanide ingestion OR smoke inhalation with altered MS + lactate >8 + hypotension (ACMT cyanide-toxicity guidance)(life-threatening)
  • Digoxin overdose with K+ >5, ventricular arrhythmia, shock, acute ingestion >4 mg, or chronic level >4 ng/mL (ACMT digoxin-toxicity guidance)(life-threatening)
  • Adolescent intentional self-harm overdose with any toxin (AAP/AAPCC)

5. Follow-up

Pediatrician + household safe-storage counseling + AAPCC poison-prevention education for accidental; psychiatry + outpatient mental health + safety planning for intentional adolescent overdose (AAP/AAPCC; AAP Bright Futures)
