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:
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 ...
People affected by subglottic stenosis have a FEV1 of over 10. [2] Subglottic stenosis is graded according to the Cotton-Myer classification system from one to four based on the severity of the blockage. Grade 1 is up to 50% obstruction, Grade 2 is 50-70% obstruction, Grade 3 is 70-99% obstruction, and Grade 4 is with no visible lumen. [5]
Sir Robert Macintosh (1897–1989) introduced a curved laryngoscope blade in 1943; [131] the Macintosh blade remains to this day the most widely used laryngoscope blade for orotracheal intubation. [10] Between 1945 and 1952, optical engineers built upon the earlier work of Rudolph Schindler (1888–1968), developing the first gastrocamera. [132]
Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body. Patients are generally anesthetized beforehand. Examples include tracheal intubation , and the balloon tamponade with a Sengstaken–Blakemore tube (a tube into the gastrointestinal tract ).

The simplicity of placement is the main advantage of the Combitube over endotracheal intubation. When intubating with a traditional endotracheal tube, care must be taken to visually ensure that the tube has been placed in the trachea while the dual-lumen design of the Combitube allows for ventilation to proceed regardless of esophageal or ...
