Accidental Ingestion of Plaster of Paris Causing Thermal Injury of the Esophagus and Stomach in a Toddler

Abstract

Background: Plaster of Paris (POP) or calcium sulfate hemihydrate is commonly used in regular construction activities and medical appliances. Due to its easy availability, young children can be at risk of exposure. Mixing of POP with water results in exothermic reaction and production of heat. We report the acute endoscopic findings of thermal burn of the gastrointestinal mucosa, following accidental ingestion. Clinical Description: A 21-month-old boy presented with acute hematemesis in our emergency department with his mother giving a history of having noticed his fist full of POP. The child was otherwise stable, afebrile with swollen cheeks, lips, and oral mucosa with some crusting. Management and Outcome: The child was provided supportive care, and an early endoscopy was carried out, which revealed POP causing thermal injury of the mucosa of Zargar 2A grade. Conclusion: Our purpose of reporting this case is to highlight the less known deleterious effects of POP on the gastrointestinal mucosa and the importance of early endoscopic diagnosis, management along the lines of corrosive poisoning. Warning labels over the packets of POP and making them inaccessible to children are absolutely essential.
