What are the immediate concerns and management for an 8-year-old girl with no past medical history who ingested a quarter, with an x-ray showing the quarter in the distal esophagus and presenting with bradypnea?

Management of Coin Ingestion in an 8-Year-Old with Distal Esophageal Foreign Body and Bradypnea

Urgent endoscopic removal of the quarter is required due to the distal esophageal impaction and concerning respiratory rate of 14, which indicates potential airway compromise or mediastinal complications.

Immediate Concerns

The primary concerns in this case include:

1. Respiratory compromise:

   • The low respiratory rate (bradypnea) of 14 is concerning and may indicate:
     • Potential pressure on the trachea from the esophageal foreign body
     • Early signs of mediastinal complications
     • Possible vagal stimulation from the esophageal impaction

2. Risk of esophageal perforation:

   • Coins lodged in the esophagus can cause pressure necrosis
   • The distal esophagus location increases risk of perforation with prolonged impaction
   • Any perforation could lead to mediastinitis, a life-threatening complication

3. Complete esophageal obstruction:

   • May lead to inability to handle secretions and risk of aspiration
   • Can cause significant discomfort and distress

Diagnostic Approach

• X-ray findings: Already confirmed quarter in distal esophagus
• Additional imaging: Consider CT scan if perforation is suspected based on clinical presentation 1
• Avoid contrast studies: These should not be performed as they may delay intervention and increase aspiration risk 1

Management Algorithm

Step 1: Immediate Assessment

• Assess airway stability and oxygen saturation
• Monitor vital signs including respiratory rate, heart rate, and temperature
• Evaluate for signs of perforation (chest pain, fever, subcutaneous emphysema)
• Check ability to swallow saliva (indicates partial vs. complete obstruction)

Step 2: Endoscopic Intervention

• Timing: Urgent flexible endoscopy within 24 hours, preferably sooner given the respiratory concerns 1, 2
• Procedure type: Flexible endoscopy is first-line approach 1
• Anesthesia considerations:
  • General anesthesia with endotracheal intubation to protect airway
  • Continuous monitoring of vital signs during and after procedure 1

Step 3: Removal Technique

• Retrieval using appropriate tools (baskets, snares, grasping forceps)
• Consider gentle pushing of the coin into the stomach if retrieval is difficult and there's no evidence of perforation 1
• Inspect esophageal mucosa for signs of injury after foreign body removal

Step 4: Post-Procedure Care

• Close observation for at least 2 hours after the procedure 1, 2
• Monitor vital signs, particularly respiratory rate
• Ensure patient can tolerate oral fluids before discharge
• Observe for signs of perforation (pain, fever, respiratory distress)

Special Considerations

• Respiratory monitoring: The bradypnea requires close monitoring as it may indicate early complications
• Perforation risk: Suspect perforation if the patient develops pain, breathlessness, fever, or tachycardia 1
• Diagnostic workup: Consider evaluation for underlying esophageal disorders after resolution of acute issue, as up to 25% of patients with foreign body impaction have underlying conditions 1, 2

Potential Complications

• Perforation: Reported in 1-3% of cases, higher risk with prolonged impaction 1
• Aspiration: Risk increases with complete obstruction and respiratory compromise
• Pressure necrosis: Can occur with prolonged foreign body impaction

Surgical Considerations

Surgical intervention is rarely needed but should be considered if:

• Endoscopic removal is unsuccessful
• Evidence of perforation with extensive contamination
• Development of mediastinitis or other severe complications 1

Follow-up

• Ensure complete resolution of respiratory symptoms
• Consider repeat imaging if symptoms persist after removal
• Evaluate for underlying esophageal pathology that may have contributed to the impaction

The combination of distal esophageal foreign body and bradypnea makes this case urgent, requiring prompt endoscopic intervention to prevent potentially life-threatening complications.
