Laryngoscopy for intubation should not apply force to the patient’s maxillary incisors, but pressure often is applied when intubation is difficult. Researchers compared pressure exerted on the maxillary teeth during conventional direct laryngoscopy using a Macintosh 3 blade with that exerted during video laryngoscopy using a Storz video laryngoscope. Anesthesiologists who were experienced with both instruments (>30 previous uses) performed laryngoscopy with each instrument, in random order, after induction of anesthesia in 24 women and 20 men who were healthy and undergoing elective general anesthesia for nonfacial surgery.
