Button Batteries: Small, disc shaped battery cells which are designed for use in small electronic devices. Common sources are kids toys, watches, calculators and hearing aids. Most batteries use lithium as a power source

Button Battery Ingestion Danger:

  • Contact with mucosal surfaces (oropharynx, esophagus, nasal passage) results in transmission of current
  • Current transmission causes chemical burns and necrosis via alkaline injury (sodium hydroxide)
  • Tissue damage can progress rapidly and result in devastating injuries
  • Nasal passage and esophagus are most susceptible to injury (narrow places for battery to become lodged)
  • Injury Patterns
    • Viscous perforation
    • Fistula formation
    • Erosion into blood vessels and resultant bleeding and possible catastrophic bleeding with erosion into aorta

Definition: A life-threatening emergency in which there is a failure of the body’s thermoregulatory mechanisms to handle extrinsic and intrinsic heat. The failure of thermoregulation leads to multi-system organ dysfunction characterized by alteration of neurologic function. Unlike in fever, hyperthermia is not caused by endogenous pyrogens that change the thermoregulation set point in the brain. Hyperthermia results from excessive heat production and/or inadequate heat dissipation
