While Mallampati classes I and II are associated with relatively easy intubation, classes III and IV are associated with increased difficulty. 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 ...
The Simplified Airway Risk Index (SARI), or El-Ganzouri Risk Index (EGRI), is a multivariate risk score thought to estimate the risk of difficult tracheal intubation. The SARI score ranges from 0 to 12 points, where a higher number of points indicates a more difficult airway. A SARI score of 4 or above is thought to indicate a difficult ...
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 glottis seen: 1.2–1.6%: 80–87.5% 4: Neither ...
Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs.
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.
4. In order to facilitate placement of the tracheal tube, the suction catheter is moved across to the left side of the mouth and the suction catheter 'parked' in the top of the oesophagus to provide continuous suction during the remainder of the intubation attempt. This can be achieved either by sliding the catheter under the laryngoscope blade ...
