A

coins
Most coin ingestions by children <2cms in diameter (dimes 18mm / pennies 19mm)

Coins are usually non-corrosive

65
Q

If it FB makes it to where, then it can usually pass safely?

A

stomach

66
Q

What are the symptoms of an esophageal FB?

A

Sudden onset of dysphagia, wheezing or respiratory distress
Dysphagia / drooling & hoarseness (caustic ingestion)
Chest discomfort
(long standing) neck / thoracic mass

67
Q

What does the diagnosis of a FB require and how is it managed?

A

Diagnosis:
–>If symptomatic Chest x-ray / ? Metal detector +/- barium swallow / CT (NO MRI!!!)

Management:
Heimlich maneuver may lead to esophageal rupture
(AAP) 4 x strong back blows followed by chest trusts
Observation
Endoscopic removal / surgical referral

68
Q

Caustic ingestions can lead to…

A

perofrations and strictures

69
Q

How do you manage caustic ingestions

A

Early neutralization (orange juice / cola) has been shown to decrease esophageal injury
**Do not induce vomiting
**Do not pass NG tube to gastric lavage
