Management of a Child Who Has Swallowed a Foreign Object
Most children who swallow non-sharp foreign objects like marbles do not require hospital admission and can be managed with observation at home, provided they are asymptomatic and the object is confirmed to have passed into the stomach.
Assessment Algorithm for Ingested Foreign Bodies
Initial Evaluation
- Determine if the child is symptomatic (coughing, gagging, stridor, wheezing, respiratory distress, vomiting, or abdominal pain)
- Identify the type of object swallowed (size, shape, composition)
- Assess timing of ingestion
Risk Stratification
High-risk situations requiring immediate intervention:
- Signs of airway obstruction or respiratory distress
- Sharp objects (pins, needles, bones)
- Button batteries
- Magnets
- Complete esophageal occlusion
- Symptomatic patients (inability to swallow, pain, vomiting)
Moderate-risk situations requiring urgent evaluation:
- Objects lodged in the esophagus
- Large objects (>2.5 cm in diameter)
- Multiple objects
Low-risk situations suitable for home observation:
- Small, smooth objects (like marbles) confirmed to have passed to the stomach
- Asymptomatic patient
- No pre-existing GI tract abnormalities
Management Recommendations
For Marbles and Similar Objects
If a child has swallowed a marble and is asymptomatic:
- Radiographic confirmation that the object has passed into the stomach is recommended
- Home observation is appropriate with parental education 1
- Parents should monitor stool for passage of the object
- Return for evaluation if symptoms develop (abdominal pain, vomiting, fever)
The American Academy of Pediatrics notes that most foreign bodies that reach the stomach will pass through the intestinal tract without complications 1. Coin-related choking episodes (similar in size to marbles) are usually transient, with the object typically being swallowed and passing through the gastrointestinal tract without problems 1.
Warning Signs Requiring Immediate Medical Attention
Parents should be instructed to seek immediate medical care if the child develops:
- Difficulty breathing or swallowing
- Drooling
- Vomiting
- Refusal to eat
- Abdominal pain or distension
- Fever
- No passage of the object within 3-5 days
Special Considerations
Choking Risk
If active choking occurs, appropriate age-specific maneuvers should be performed 1:
- For a child: perform subdiaphragmatic abdominal thrusts (Heimlich maneuver)
- For an infant: deliver repeated cycles of 5 back blows followed by 5 chest compressions
- If the victim becomes unresponsive, start CPR with chest compressions
Complications to Monitor
While most foreign bodies pass spontaneously, complications can occur in approximately 10% of cases 2, including:
- Esophageal perforation
- Mediastinitis
- Peritonitis
- Hemorrhagic gastritis
Follow-up Recommendations
- Confirm passage of the object through stool examination
- If the object is not visualized in stool within 7 days and the child remains asymptomatic, consider follow-up radiography
- If the object fails to progress for more than 7 days, further evaluation may be needed 3
Evidence Quality
The evidence regarding management of swallowed foreign bodies in children is largely based on observational studies and expert consensus rather than randomized controlled trials. Guidelines consistently support conservative management for asymptomatic children who have swallowed smooth, non-sharp objects that have passed into the stomach.
