Worth the read if you are ever around any kids!!
đ¨ When the Call Comes In
You ever get that gut-drop call from dispatch- âpossible battery ingestionâ? Yeah, that one. You can feel your pulse climb before you even turn the key. Because hereâs the truth: those shiny little lithium coin cells arenât choking hazards. Theyâre chemical grenades once they hit moisture.
Iâve seen a toddler who looked fine. Laughing even and by the time we got x-rays, the esophagus was basically a charred crater. You donât forget that kind of thing.

⥠Whatâs Actually Going On Inside
Lithium coin batteries pack 3 volts, compared to the old 1.5-volt alkaline or silver oxide cells. That extra juice turns saliva into a science experiment from hell. The second that battery gets stuck in the esophagus, current starts flowing. Electrolysis kicks in, the negative pole spits out hydroxide ions, and the tissue pH skyrockets above 12. Thatâs like dunking the esophagus in drain cleaner.
Within 15 minutes, the burn starts. By two hours, youâre looking at deep necrosis, holes, perforation, and surgical emergencies nobody wants. The scary part? The kid might look totally fine.
Even after removal, the chemical reaction keeps cooking. Reperfusion injury adds fuel to the fire, and days later you can see tracheoesophageal fistulas, vocal cord paralysis, or even a fatal aortoesophageal fistula.

đ Why Lithium Is So Much Worse
Lithium = more voltage = more current = more tissue destruction. Theyâre smaller too, so they wedge perfectly in a childâs esophagus. And unlike older batteries, they donât just leak acid; they generate it on contact.
Alkaline cells might irritate. Lithium ones cook.

đ§ The Water Myth: Will It Explode?
Nope. Button batteries donât explode in the body. Theyâre not like v**e pen or laptop lithium-ion packs that fail thermally. These little ones burn chemically.
But hereâs the catch: do not give water, milk, or food; keep NPO per guideline. Honey is the only endorsed interim agent for âĽ12 months.
If the childâs over 12 months old, alert, and swallowing safely, give 10 mL of honey every 10 minutes, up to six doses, while youâre hauling tail to the ED. Honey coats the battery, reduces current flow, and slows the burn. Thatâs straight from the National Capital Poison Center.

đ Field Game Plan for EMS and Nurses
1. Suspect early. Unexplained drooling, vomiting, chest pain, or refusal to eat in a toddler? Think battery until proven otherwise.
2. Keep NPO. No food, no drinks, no antacids.
3. Honey protocol: 10 mL every 10 minutes up to six doses (âĽ12 months, alert, able to swallow).
4. Transport immediately. Time is tissue.
5. Call Poison Control: 1-800-222-1222 â theyâll update and coordinate.
6. Document ingestion time and battery type if known.

đĽ What Happens in the ED (And Why You Should Know)
The ED team will grab AP and lateral neck/chest x-rays to find that tell-tale âdouble-ringâ sign.
If itâs stuck in the esophagus, endoscopic removal within 2 hours; no arguments.
They might use sucralfate suspension (1 g/10 mL, 10 mL every 10 minutes Ă 3 doses) while prepping.
Some centers irrigate post-removal or apply weak acid solutions to neutralize residual burn, but thatâs specialist work.
If the batteryâs already in the stomach, theyâll monitor, especially in kids under six or if the batteryâs âĽ20 mm. Watch for delayed complications like bleeding, cough, or voice change.
Full guidelines are detailed in ESPGHANâs 2021 position statement.

đĄ Field Pearls to Live By
⢠A smiling toddler can still have a dying esophagus. Donât get comfortable.
⢠Always check if thereâs a second battery missing.
⢠Magnets + batteries = surgical nightmare.
⢠Even after removal, delayed fistulas can appear days later.
⢠Always educate caregivers: watch for bloody emesis, persistent cough, or hoarseness.

đ§ Takeaway
Lithium button batteries arenât harmless power cells. Theyâre 3-volt alkali generators with one missionâburn through tissue.
If you suspect it, move fast.
Honey buys you minutes, transport buys survival, and teamwork seals the deal.
And the kid? Heâll probably be giggling while youâre sweating bullets, calling ahead, and praying radiologyâs ready.
Thatâs this jobâequal parts chaos and chemistry.
