Airway Scope®: initial clinical experience with novice personnel

Comparing video and direct laryngoscopes for pediatric intubation during cardiopulmonary resuscitation

“…Nouruzi-Sedeh et al [3] showed that untrained medical personnel required only 5 tracheal intubation attempts to achieve proficiency with the GlideScope in patients with a normal airway. Hirabayashi [4] found that a short demonstration of the Pentax-AWS and a brief practice with a manikin were the only requirements needed to perfect a tracheal intubation with this device. Thus, in the study by Szarpak et al [1], identical training times for the 4 studied devices may have biased both the intubation time and success rate in favor of 3 videolaryngoscopes.…”

Failure of the Airway Scope to reach the larynx

“…2 We, however, encountered a case in which the INTLOCK, the blade of the AWS, could not proceed beneath the epiglottis, and consequently the AWS failed to intubate the patient's trachea, probably because the distance from the mouth to the larynx of the patient was longer than the designed length of the INTLOCK.…”

Tracheal intubations performed with a Macintosh laryngoscope and videolaryngoscopes on a mannequin simulating cardiac arrest

“…NouruziSedeh et al 2 showed that untrained personnel required only five tracheal intubation attempts to achieve proficiency with the GlideScope Ò in patients with a normal airway. Also, Hirabayashi 3 found that a short demonstration of the Pentax-AWS Ò and a brief practice with a mannequin were the only requirements needed to perform a tracheal intubation with the device. However, in the studies of Mulcaster et al 4 and Konrad et al, 5 novice anesthesia residents or non-anesthesia trainees required 47-56 tracheal intubations to achieve a tracheal intubation success rate of C 90% using direct laryngoscopy.…”
