The use of video
laryngoscopes has
increased significant-
ly during the pan-
demic among providers who are increasingly worried about their prox-
imity to the patient's airway, according to Dr. Aziz. "The devices were
gaining a stronger foothold because clinical evidence shows higher
rates of first pass intubation success," he says. "Some providers had
already been using them universally. Many who weren't are now discov-
ering the benefits they provide."
Video laryngoscopes, which provide direct views of the glottis to
make intubation much easier, have evolved since first being intro-
duced as a "game-changing" technology about a decade ago. The lat-
est generation of devices are more ergonomic and portable, and fea-
ture high-definition imaging that provides clearer views of airway
anatomy. They also accommodate various laryngoscope blade
designs. Dr. Aziz says providers often use standard blades for routine
intubations and acute angle blades to secure anticipated difficult air-
ways.
Screen size matters most to Dr. Aziz. "Units with smaller, attached
screens are priced competitively, but the visualization and magnifica-
tion capabilities afforded by larger screens allow for improved intuba-
tion performance," he says.
Dr. Aziz also points out devices with larger, detachable screens let
providers keep a healthy distance from the airway. "We're never cer-
tain about who's shedding the coronavirus, even with testing in
place," he says. "Video laryngoscopes with separate monitors that can
be positioned next to the patient let providers stand upright while intu-
bating instead of leaning directly over the airway to perform direct
laryngoscopy or manipulate a video laryngoscope with an integrated
