Atelectasis in children

Area of Science:

• Pediatric Pulmonology
• Diagnostic Imaging
• Interventional Pulmonology

Background:

• Clinical signs in children with lower respiratory tract symptoms are often insufficient to differentiate conditions like pneumonic consolidation, foreign body aspiration, and atelectasis.
• Radiology and bronchoscopy are crucial for definitive etiological identification.

Purpose of the Study:

• To analyze clinical and radiological signs of atelectasis in children with acute and chronic lower respiratory tract symptoms.
• To evaluate the diagnostic utility of clinical findings, radiological signs, and bronchoscopy in pediatric atelectasis.

Main Methods:

• Prospective study involving 35 children with acute or chronic lower respiratory tract symptomatology.
• Clinical assessment for signs like localized loss of breath sounds and mediastinal shift.
• Radiological evaluation including assessment for tracheal shift, elevated hemidiaphragm, and silhouette sign.
• Diagnostic and/or therapeutic bronchoscopy in selected cases.

Main Results:

• Atelectasis was diagnosed in 35 children, with 23 in the acute group and 12 in the chronic group.
• Clinical recognition of atelectasis was low (8/35).
• Radiological signs, particularly the silhouette sign (21/35 cases), were important for diagnosing clinically missed atelectasis.
• Bronchoscopy identified foreign bodies (n=5), mucus plugs (n=4), bronchial narrowing (n=4), and inflammatory secretions (n=8) without major complications.

Conclusions:

• Diagnosing atelectasis in children presents challenges.
• A high index of suspicion is necessary to exclude atelectasis in pediatric patients with respiratory symptoms.
• Radiological and bronchoscopic evaluations are vital for accurate diagnosis and management.
