An 1818-month-old boy is brought to the pediatric clinic by his parents due to a persistent cough for the past 33 weeks. The parents state the cough began suddenly while he was eating mixed nuts at a family gathering. He coughed vigorously for a few minutes, but the choking episode seemingly resolved. Over the following weeks, he developed a daily, harsh cough. He was evaluated at an urgent care center two weeks ago and completed a 1010-day course of high-dose oral amoxicillin for suspected community-acquired pneumonia, but his symptoms have not improved. Today, his temperature is 37.2∘C37.2^\circ\text{C} (99.0∘F99.0^\circ\text{F}), pulse is 120/min120/\text{min}, respirations are 28/min28/\text{min}, and oxygen saturation is 96%96\% on room air. Physical examination reveals diminished breath sounds and localized, monophonic expiratory wheezing over the right lower lung field. The left lung field is clear to auscultation. A chest radiograph reveals volume loss in the right lower lobe with no radiopaque structures visualized. Which of the following is the most appropriate next step in management?

  1. Rigid bronchoscopyCevap
  2. B
    Administration of intravenous ceftriaxone
  3. C
    Administration of oral azithromycin
  4. D
    Administration of nebulized albuterol
  5. E
    Initiation of inhaled fluticasone

Cevap

Rigid bronchoscopy
The correct answer is rigid bronchoscopy. This patient has a classic presentation of a retained radiolucent foreign body (e.g., a peanut). The sudden onset of symptoms while eating, combined with focal monophonic wheezing, decreased breath sounds, and unresolved post-obstructive atelectasis despite appropriate antibiotic therapy, strongly points to foreign body aspiration (FBA). Most aspirated organic objects are radiolucent and will not appear on a standard chest radiograph, but they frequently cause distal atelectasis (volume loss) or hyperinflation due to a ball-valve effect. Rigid bronchoscopy is the procedure of choice for the diagnosis and removal of aspirated foreign bodies in children, as it allows for secure airway control, better visualization, and the use of large grasping forceps for extraction.

Adım Adım Çözüm

1
Analyze the patient's history and timeline of symptoms.
An 1818-month-old with a sudden onset of choking on nuts followed by a 33-week persistent cough that failed antibiotic therapy.
To differentiate between an infectious etiology and a mechanical airway obstruction.
2
Evaluate the physical examination and radiographic findings.
Focal monophonic wheezing, decreased breath sounds on the right, and right lower lobe atelectasis on the chest radiograph.
To localize the pathology; unilateral, localized lung findings strongly suggest a localized airway obstruction (like a foreign body) rather than a systemic or diffuse disease like asthma or typical pneumonia.
3
Determine the definitive diagnostic and therapeutic intervention.
Select rigid bronchoscopy as the next step.
Rigid bronchoscopy is the standard of care for visualizing and extracting aspirated foreign bodies in pediatric patients, as it provides optimal airway control and working channels.

Alternatif Yöntem

In cases where the history is ambiguous and the patient is completely asymptomatic, a decubitus chest radiograph may be obtained to look for air trapping (failure of the dependent lung to deflate), but with a positive history and abnormal focal physical exam, rigid bronchoscopy is directly indicated.
