Study Notes
Mallampati Classification
- Class I: Visualization includes the soft palate, fauces, uvula, and anterior and posterior pillars.
- Class II: Visualization includes the soft palate, fauces, and uvula.
- Class III: Visualization includes the soft palate and the base of the uvula.
- Class IV: Soft palate is not visible at all.
Intubation Insights
- Class I view indicates ease of intubation, correlating with a laryngoscopic view grade I (99-100% accuracy).
- Class IV view indicates poor laryngoscopic view, consistently correlating with grade III or IV (100% accuracy).
- Intermediate classes (II and III) may lead to varying degrees of difficulty in laryngoscopic visualization.
Laryngoscopic Views
- Grade I: Most of the glottic opening is visible.
- Grade II: Only the posterior portion of the glottis or the arytenoid cartilages can be seen.
- Grade III: Only the epiglottis is visible; no glottis is seen.
- Grade IV: Neither the glottis nor the epiglottis is visible.
Mandibular Protrusion Test
- Upper lip bite test is also known as the Mandibular protrusion test.
- Class A: Lower incisor can protrude anterior to the upper incisor.
- Class B: Lower incisor can meet the upper incisor edge to edge.
- Class C: Lower incisor cannot reach the upper incisor edge to edge.
Difficult Airway Predictors
- Ten predictors of a difficult airway include:
- Short muscular neck
- Protruding incisors (buck teeth)
- Long, high, arched palate
- Receding lower jaw
- Poor mandible mobility
- Large tongue
- Limited neck extension
- Short thyromental distance
