A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult bag mask ventilation.
Mallampati score: Class I and II of the modified mallampati scoring results in 0 points whereas a class III is given 1 point and a class IV 2 points. Movement of the neck: The ability to move the neck more than 90 degrees results in 0 points whereas a movement range of 80-90 degrees results in 1 point and a movement range below 80 degrees ...
Many classification systems have been developed in an effort to predict difficulty of tracheal intubation, including the Cormack-Lehane classification system, [74] the Intubation Difficulty Scale (IDS), [75] and the Mallampati score. [76] The Mallampati score is drawn from the observation that the size of the base of the tongue influences the ...

Modified Cormack–Lehane classification. [2] [3] Grade Description Approximate frequency Likelihood of difficult intubation 1: Full view of glottis: 68–74% <1% 2a: Partial view of glottis: 21–24%: 4.3–13.4% 2b: Only posterior extremity of glottis seen or only arytenoid cartilages: 3.3–6.5%: 65–67.4% 3: Only epiglottis seen, none of ...
[20] [21] The most commonly performed airway assessment is the Mallampati score, which evaluates the airway base on the ability to view airway structures with the mouth open and the tongue protruding. Mallampati tests alone have limited accuracy, and other evaluations are routinely performed addition to the Mallampati test including mouth ...
In 1983, Mallampati published a letter describing a difficult intubation in a female patient whose mouth could open widely but whose tongue obstructed view of the faucial pillars and uvula. [2] He hypothesised that the size of the tongue was a significant factor in predicting difficult laryngoscope usage since a large tongue would likely ...
In anaesthesia and advanced airway management, rapid sequence induction (RSI) – also referred to as rapid sequence intubation or as rapid sequence induction and intubation (RSII) or as crash induction [1] – is a special process for endotracheal intubation that is used where the patient is at a high risk of pulmonary aspiration.
