Insights
A case study highlights the risks of nickel-metal hydride (NiMH) battery ingestion in children. Prompt medical management is crucial to prevent serious gastrointestinal complications from swallowed NiMH batteries.
Area of Science:
- Pediatric Emergency Medicine
- Toxicology
- Gastroenterology
Background:
- Ingestion of foreign bodies is common in children.
- Nickel-metal hydride (NiMH) batteries pose a unique risk due to potential gastrointestinal complications.
- Limited literature exists on NiMH battery ingestion complications.
Abstract:
We describe a case of a 12-year-old female with a past history of autism spectrum disorder who presented to the emergency department of a rural hospital in Australia after ingesting two nickel-metal hydride (NiMH) batteries at home. Hitherto, no literature has described any gastrointestinal complications related to NiMH battery ingestion. This paper aims to provide insight into the management of NiMH battery ingestion and to increase the awareness of the need for prompt management to prevent further damage to the gastrointestinal tract.

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
