Q

Standard Preanesthetic Airway Assessment

A
  1. Mouth Opening: 3cm incisor opening
  2. Thyromental distance: 3 fingerbreaths
  3. Neck Circumference: >17in associated with difficult airway
  4. Prominent overbite, neck ROM, shape of palate
  5. Mallampati: size of tongue relation to oral cavity- more pharyngeal structures are obstruction more difficult intubation
