Powder aspiration in children. Report of two cases
Insights
Powder aspiration in infants can cause severe respiratory distress hours after exposure. Immediate tracheal intubation and bronchial wash-out, even without symptoms, improves outcomes and reduces mortality risk.
Area of Science:
- Pediatric Pulmonology
- Emergency Medicine
Background:
- Powder aspiration in infants presents a significant risk for acute respiratory distress.
- Delayed onset of symptoms is common, complicating early diagnosis and intervention.
Observation:
- A 7 1/2-month-old girl experienced a 3-4 hour asymptomatic period before severe respiratory distress, requiring 10 days of mechanical ventilation and developing complications.
- A 13-month-old boy underwent immediate tracheal intubation and bronchial wash-out after massive powder aspiration, with an uneventful recovery and no respiratory distress.
Findings:
- Powder aspiration causes delayed, severe bronchiolar obstruction with a high mortality rate.
- Immediate tracheal intubation and bronchial wash-out are crucial for managing powder aspiration, regardless of initial symptoms.
Implications:
- Prompt intervention, including intubation and bronchial wash-out, is vital for improving survival rates in powder aspiration cases.
- Mechanical ventilation may be necessary to manage high airway resistance, and corticosteroids/bronchodilators may aid treatment.
Abstract:
Two cases of powder aspiration are reported. A 7 1/2-month-old girl showed a classical course with an asymptomatic period of 3-4 hours, then severe respiratory distress developed. Acute respiratory insufficiency made tracheal intubation and mechanical ventilation necessary for 10 days. Complications included insufficient alveolar ventilation, atelectasis, pneumothorax, and superinfection. But the baby recovered with some residual radiological changes in the lungs. A 13-month-old boy was treated immediately after massive powder aspiration by tracheal intubation and bronchial wash-out. The postoperative course was unevetful and no respiratory distress developed. Powder aspiration leads to severe bronchiolar obstruction with a delay of several hours and has a high mortality rate. The best results in treatment are obtained by immediate intubation and bronchial wash-out, even in the absence of respiratory symptoms. Artifical ventilation may be necessary with the special problem of overcoming very high airway resistance. Corticosteroids and bronchodilators may be helpful.
