Intussusception is a life-threatening emergency, and its reduction is an urgent treatment measure that should be performed immediately once diagnosed. In the early stages, the child generally appears healthy, with normal body temperature and no obvious symptoms of poisoning. However, as the condition progresses and the duration of the intussusception increases, it can lead to intestinal necrosis or peritonitis, causing a deterioration in the overall condition. Commonly, severe dehydration, high fever, coma, shock, and other serious symptoms of poisoning may occur.
