What is the most appropriate action to take when treating an infant with intussusception?

In the management of intussusception in infants, performing an air enema is considered the most appropriate action. This procedure not only serves as a diagnostic tool but can also have a therapeutic effect. During the air enema, air is introduced into the colon, and this process can potentially help reduce the intussusception, allowing the involved bowel segments to return to their normal position. This non-invasive approach is favored initially due to its effectiveness and lower risk compared to surgery.

Although surgery may ultimately be required if the air enema is unsuccessful or if there are complications, such as signs of bowel perforation or necrosis, it is not the first line of treatment. Corticosteroids and antibiotics do not address the underlying problem of intussusception and are not appropriate as primary interventions for this condition.
