Foreign Body Aspiration Management
A 3-year-old girl is brought in 4 hours after she coughed violently while eating peanuts. She now has persistent cough and mild respiratory distress. Auscultation shows decreased breath sounds and monophonic wheeze over the right chest. Chest radiography shows hyperinflation of the right lung with mediastinal shift to the left on expiration and no radiopaque object. She is stable for a planned procedure. What is the most appropriate definitive management?
- A.Contrast-enhanced computed tomography of the chest
- B.Flexible bronchoscopy under conscious sedation
- C.Rigid bronchoscopy under general anesthesiaCorrect
- D.Nebulized beta-2 agonist with chest physiotherapy
Explanation
Rigid bronchoscopy under general anesthesia is both the diagnostic gold standard and the therapeutic procedure for an aspirated airway foreign body in children. The rigid scope maintains a secure ventilating airway, allows large optical forceps to grasp irregular objects such as peanut fragments, and permits control of bleeding or granulation tissue at the impaction site. Flexible bronchoscopy may be used to inspect the airway when the diagnosis is uncertain, but its working channel is too small for reliable extraction of solid food, and attempting removal risks dislodging the object into a more central and life-threatening position. Computed tomography can map a suspected foreign body when the history and radiographs are equivocal, but in a case this clear it only delays definitive care and adds radiation. Bronchodilators and chest physiotherapy have no role and are actively dangerous, since physiotherapy can mobilize a peripheral object into the trachea and cause complete obstruction. The expiratory film findings of air trapping and mediastinal shift away from the affected side reflect a ball-valve effect from partial obstruction, and normal radiographs do not rule out aspiration because most aspirated foods are radiolucent. Delay leads to granulation tissue, post-obstructive pneumonia, atelectasis, and eventually bronchiectasis. If the child were in complete obstruction with inability to speak or cough, immediate back blows and chest thrusts in infants or abdominal thrusts in older children would take precedence over any scheduled procedure.
Why each option
- A.
- Computed tomography may help in equivocal cases but is unnecessary here and delays the definitive procedure.
- B.
- Flexible bronchoscopy is useful for airway inspection but lacks a secure airway and instruments adequate for extracting solid food.
- C.
- Correct. Rigid bronchoscopy under general anesthesia secures ventilation and allows both confirmation and removal of the object.
- D.
- Bronchodilators do not relieve mechanical obstruction, and chest physiotherapy risks dislodging the object into the trachea.
