Activity Description

The procedure of endotracheal intubation plays an important role in maintaining a patient's airway in various clinical scenarios, such as surgeries and critical care. However, this process can be challenging in certain patients due to anatomical variations, commonly referred to as 'difficult airways.' Clinicians can utilize the 3-3-2 rule as a predictive tool to identify and prepare for these challenging scenarios in advance to minimize complications. The 3-3-2 rule involves measuring 3 different distances in the patient's neck using the clinician's fingers. These measurements aid in predicting the ease or difficulty of intubation. Additional tools such as the LEMON scale and the Mallampati scoring system also play a valuable role in the evaluation of the airway. This activity provides an overview of the procedures and techniques involved in endotracheal intubation, with a particular emphasis on the application of the 3-3-2 rule. It also highlights the role of the interprofessional team in efficiently managing patients who require intubation.


Target Audience

This activity has been designed to meet the educational needs of physicians.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Screen patients with difficult airways using the 3-3-2 rule to promptly recognize individuals who may require special consideration and preparation for airway management.
  • Differentiate airway classes using the Mallampati scoring system to assess the visibility of specific anatomical structures during a mouth-wide-open examination.
  • Evaluate for airway obstruction as part of the LEMON scale to stratify patients based on their risk of difficult airway.
  • Collaborate with anesthesiologists, surgeons, and other relevant healthcare professionals to develop comprehensive airway management plans based on the results of the 3-3-2 rule assessment.

Good additions to the traditional airway exam. Thanks. One question is weird, where an anesthetist tries to intubate an adult female using 100 mcg of fentanyl. I know no anesthetist who would attempt intubation with such an inadequate dose of medication. Seems odd.
