Characteristics: This type involves contamination from trauma to airway structures, such as fractures, lacerations, or burns, which introduces external contaminants and increases the risk of infection or obstruction.
Anesthetic Techniques: Techniques like awake intubation or cricothyrotomy are often indicated when conventional approaches may worsen airway damage.
Equipment Selection: Advanced devices such as fiberoptic bronchoscopes, tracheostomy kits, soft-tip stylets, or laryngeal mask airways (LMAs) are essential to ensure safe management while avoiding further trauma.
| Type | Preferred anesthetic technique | Key equipment |
|---|---|---|
| Infectious | Maintain patency without spreading infection — awake fiberoptic intubation or video laryngoscopy to minimize trauma and pathogen dissemination | Fiberoptic bronchoscope; closed suction systems; HEPA filters |
| Foreign body | Avoid dislodgement or further displacement — RSI with minimal airway manipulation | Rigid bronchoscope and forceps; suction catheters to clear secretions and maintain patency |
| Chemical | Limit further chemical lung injury and aspiration on induction — RSI with cricoid pressure | Video laryngoscope with anti-fogging; endotracheal tube with subglottic suction port |
| Traumatic | Awake intubation or cricothyrotomy when conventional approaches may worsen airway damage | Fiberoptic bronchoscope; tracheostomy kit; soft-tip stylet; laryngeal mask airway; high-frequency jet ventilation for airway surgery or traumatic airway injury, where conventional ventilation risks further damage |
