Provide a brief summary of this surgical procedure and its indications here.

Indications

• Hemorrhage an infected abscess into a single lung requiring isolation
• Controlled distributed ventilation for surgery
• Bronchopleural fistula, large lung bulla and or cysts
• Tracheobronchial disruption
• Single-lung lavage for pulmonary alveolar proteinosis

Contraindications

• Known difficult airway
• Tracheal stenosis
• Severe airway distortion

Setup

Operating room setup

• DLT with appropriately chosen size
• Laryngoscope (video or direct laryngoscope)
• Syringes 3mL (bronchial cuff) and 10mL (tracheal cuff)
• Fiberoptic bronchoscope for confirming post-placement position
• Consider tooth guard to prevent shearing tracheal balloon during placement

Tube Selection Selection

• Most single-lung ventilation procedures can be accomplished with a left-sided DLT
• Right DLT indications
  • Left pneumonectomy
  • Left lung transplant
  • Trauma to the left mainstem bronchus
  • Left tracheobronchial repair
  • Consider for left thoracoscopic lung procedures (can be accomplished with L-DLT as well)

Tube Size Selection

Several sources of literature help anesthesiologists choose the correct size DLT:

1. Pedoto (2012)
2. Brodsky et al. (1999)
3. Hao etl al. (2021)

Complications

• Laryngitis
• Tracheal irritation
• Vocal cord palsy
• Airway rupture or perforation (<1% total incidence): trachea (52.4%) and left main bronchus (37.4%) are the most common sites
