Bronchopleural fistula: Ventilator management

Clinical - Respiratory/Pulmonary

  1. rupture of a bronchus, bulla, cyst, or abscess
  2. erosion due to carcinoma or inflammatory disease
  3. stump dehiscence status post pneumonectomy
  4. Ventilator management is difficult because
  5. positive pressure ventilation may lead to tension pneumothorax
  6. air leak from the fistula can lead to inadequate oxygenation and ventilation

A chest drain can reduce the chance of tension pneumothorax with PPV.

High frequency jet ventilation with permissive hypercapnia avoids the need for a DLT or SLT with blocker. HFJV avoids barotrauma to the other lung and decreases the air leak.

If high frequency jet ventilation is not available, BP fistula is one of the strict indications for split lung (i.e. DLT) ventilation.
