What is Cormack-Lehane scale?

What is Cormack-Lehane scale?

The Cormack-Lehane system classifies views obtained by direct laryngoscopy based on the structures seen. It was initially described by R.S. Cormack and J. Lehane in 1984 as a way of simulating potential scenarios that trainee anaesthetists might face.

What classification system uses numeric grading from 1 to 4 to score the views obtained during laryngoscopy?

The Cormack-Lehane scoring system classifies laryngoscopy by the best view obtained. A grade 1 score represents full visualization of the glottis, grade 2 is a partial view, grade 3 is epiglottis only, and grade 4 indicates that no laryngeal structure was seen.

What is grade 2 on the Cormack-Lehane grading scale?

With this scale, a grade I view connotes a full view of the entire glottic aperture, grade II represents a partial glottic view, grade III represents visualization of the epiglottis only, and grade IV represents inability to visualize even the epiglottis.

What is a grade 4 airway?

Getting good ‘grades’ If you see the entire glottis after positioning the laryngoscope, that is a Grade 1 Airway. If you have a partial view, that’s a Grade 2. If you can only see the epiglottis, that’s a Grade 3. If you cannot see the epiglottis, that’s a Grade 4, or very difficult.

How is Thyromental distance measured?

1 Thyromental Distance The thyromental distance (TMD) is defined as the distance from the chin (mentum) to the top of the notch of the thyroid cartilage with the head fully extended; it must be measured with a ruler for accuracy.

What is an intubation grade?

Documenting the grade of intubation is a common practice whenever a patient’s trachea is intubated for any reasons. It’s relevant specificallyfor patients who have difficulty in placing an endotracheal tube. The Laryngoscopic (Cormack & Lehane) view is normally written as grades ofintubations.
