A 45-year-old obese male scheduled for elective laparoscopic cholecystectomy is evaluated in the pre-anaesthetic clinic. On airway examination, he has a Mallampati class III view, thyromental distance of 5 cm, and limited neck extension. Which of the following is the single best predictor of difficult bag-mask ventilation in this patient?
- A.Mallampati class III
- B.Thyromental distance of 5 cm
- C.Presence of a beard and high BMICorrect answer
- D.Limited neck extension
Solution
The presence of a beard, high BMI (>26 kg/m2), advanced age (>55 years), history of snoring, and lack of teeth are classic independent predictors of difficult bag-mask ventilation (often remembered by the acronym MOANS). Mallampati class, short thyromental distance, and limited neck extension are primarily predictors of difficult direct laryngoscopy and intubation.
