PY - 2022 T2 - Current Medical Diagnosis & Treatment 2022 AB - The strong alkalies are common ingredients of some household cleaning compounds and may be suspected by their “soapy” texture. Those with alkalinity above pH 12.0 are particularly corrosive. Disk (or “button”) batteries are also a source. Alkalies cause liquefactive necrosis, which is deeply penetrating. Symptoms include burning pain in the upper gastrointestinal tract, nausea, vomiting, and difficulty in swallowing and breathing. Examination reveals destruction and edema of the affected skin and mucous membranes and bloody vomitus and stools. Radiographs may reveal evidence of perforation or the presence of radiopaque disk batteries in the esophagus or lower gastrointestinal tract.
