Core Tip

Core tip: This study shows that the introduction of video laryngoscopes has not significantly impacted the management of predicted difficult airways in the operating room; specifically, that the rate of awake fiberoptic intubation (FOI), the previous gold standard for intubating a predicted difficult airway, has not decreased. Although video laryngoscopy (VL) has clear advantages compared to direct laryngocscopy and has been proven to have increased in popularity in the operating room for non-difficult airways, we postulate that the anesthesiologist’s assessment of the ability to mask ventilate is likely a key factor in the choice of awake FOI vs VL.
