A 30-month-old male toddler presents to the emergency department with a persistent cough and noisy breathing. The symptoms began abruptly 3 hours ago during a family picnic while the child was eating trail mix. The parents witnessed a brief, severe choking episode that resolved spontaneously, but the child has had a mild cough and increased work of breathing since. His temperature is 37.0°C (98.6°F), blood pressure is 92/58 mm Hg, pulse is 124/min, and respirations are 34/min. Pulse oximetry is 95% on room air. On physical examination, the child is alert but appears mildly anxious. Lung auscultation reveals decreased breath sounds and a monophonic expiratory wheeze exclusively over the right hemithorax. A right lateral decubitus chest radiograph demonstrates hyperlucency of the right lung, with a failure of the dependent lung to deflate, and a leftward mediastinal shift. Which of the following is the most appropriate next step in management?

  1. A
    Inhaled albuterol and oral dexamethasone
  2. Rigid bronchoscopyCevap
  3. C
    Computed tomography of the chest
  4. D
    Flexible bronchoscopy
  5. E
    Intravenous ceftriaxone and azithromycin

Cevap

Rigid bronchoscopy
The most appropriate next step in management is rigid bronchoscopy. This patient's presentation—a witnessed choking episode while eating nuts, followed by unilateral wheezing and decreased breath sounds—is highly suspicious for foreign body aspiration (FBA). Because most aspirated foreign bodies in children are radiolucent (e.g., nuts, seeds), standard chest radiographs may not show the object. However, a decubitus or expiratory radiograph will often demonstrate air trapping. In a decubitus view, the dependent lung should normally deflate. The failure of this patient's right lung to deflate confirms a ball-valve obstruction in the right mainstem bronchus. Rigid bronchoscopy is the procedure of choice for FBA in children because it provides excellent visualization, allows for maintenance of ventilation, and accommodates the specialized instruments needed to safely grasp and remove the object.

Adım Adım Çözüm

1
Analyze the patient's history and presentation.
A 30-month-old child presents with abrupt onset of choking followed by a persistent cough, focal right-sided wheezing, and decreased breath sounds after eating trail mix.
These findings represent the classic clinical triad of foreign body aspiration: sudden choking, wheezing, and unilaterally decreased breath sounds.
2
Interpret the radiographic findings.
The right lateral decubitus radiograph shows hyperlucency of the right lung and failure to deflate when dependent.
Normally, a dependent lung should deflate due to gravity. Failure to deflate indicates a ball-valve effect from an aspirated radiolucent object (like a nut), which traps air during expiration.
3
Select the definitive management.
Rigid bronchoscopy is chosen as the next best step.
It is the gold standard for pediatric foreign body extraction because it allows simultaneous ventilation, airway protection, and passage of grasping instruments.

Anahtar Kavram

Foreign body aspiration typically presents in toddlers with acute choking, unilateral wheezing, and air trapping (hyperlucency on decubitus or expiratory radiographs). Rigid bronchoscopy is the standard of care for definitive evaluation and safe extraction.
