Caustic aspiration of alkaline crystals caused severe airway burns and lung necrosis. Aggressive airway management and surgery allowed patient survival in this rare case.
Area of Science:
- Pulmonology
- Toxicology
- Emergency Medicine
Background:
- Caustic aspiration leading to tracheobronchitis and lung injury is rare.
- Alkaline substances can cause severe corrosive damage to the respiratory tract.
Observation:
- A case of life-threatening acute respiratory system corrosion following aspiration of caustic alkaline crystals during a suicide attempt.
- The patient presented with severe burns of the tracheobronchial tract and liquefaction necrosis of a lung lobe.
Findings:
- Successful management involved aggressive airway protection procedures.
- Surgical resection of the destroyed lung lobe was necessary for survival.
Implications:
- This case highlights the severe consequences of caustic aspiration.
- Effective management strategies for this rare but critical condition are discussed.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
