RESUMO
BACKGROUND: The incidence of ingestion of magnetic foreign bodies in the gastrointestinal tract has been increasing year by year. Due to their strong magnetic attraction, if multiple gastrointestinal foreign bodies enter the small intestine, it can lead to serious complications such as intestinal perforation, necrosis, torsion, and bleeding. Severe cases require surgical intervention. CASE SUMMARY: We report a 6-year-old child who accidentally swallowed multiple magnetic balls. Under timely and safe anesthesia, the magnetic balls were quickly removed through gastroscopy before entering the small intestine. CONCLUSION: General anesthesia with endotracheal intubation can ensure full anesthesia under the condition of fasting for less than 6 h. In order to prevent magnetic foreign bodies from entering the small intestine, timely and effective measures must be taken to remove the foreign bodies.
