Incidence, Predictors, and Outcome of Difficult Mask Ventilation Combined with Difficult Laryngoscopy: A Report from the Multicenter Perioperative Outcomes Group, by Kheterpal et al. 

Summary: Research regarding difficult mask ventilation (DMV) combined with difficult laryngoscopy (DL) is very limited despite the fact that each technique serves as a rescue for each another. In this month’s CME selection, participants from four tertiary care centers were studied to identify predictors of DMV combined with DL using a non-parsimonious logistic regression. The authors found that DMV combined with DL is an infrequent, but not rare, phenomenon. They also found that most patients can be managed with direct or videolaryngoscopy, and that an easy-to-use, unweighted risk scale has robust discriminating capacity.

The focus of ANESTHESIOLOGY Journal CME is to educate readers on current developments in the science and clinical practice of anesthesiology.

Learning Objectives:

After completing this activity, the learner will be able to:

  • Identify predictors of combined unanticipated difficult mask ventilation (DMV) and difficult laryngoscopy (DL)

  • Anticipate the patient’s risk of combined unanticipated DMV and DL

  • Anticipate the effect of neuromuscular blocker administration on DMV and DL
