Ambu (Ballerup and Olstykke, Denmark) recently launched the Ambu
aScope (AaS), a new disposable flexible video laryngoscope specifically designed for tracheal
intubation in adult patients. The AaS consists of an
ergonometrically adapted handle with a control unit
which directs the insertion cord. The insertion cord with a maximum outer diameter of 5.3 mm, a working length of 63
cm, and a 100 degree up and down bending section is equipped with a
charge-coupled device sensor and a light emitting diode and
includes a working channel of 0.8 mm with a Luer connector for
application of local anesthetics. A power cord video cable,
emerging from the handle, attaches to a dedicated portable,
light-weight, and battery-powered liquid crystal monitor where the
resulting color image is displayed; a video output enables to
view the image on larger screens. The built-in timer limits
the use of the AsS only in a single
The costs of
the AaS flexible video laryngoscope and the monitor screen are about 230 and
1500 Euro (exclusive value-added taxes,
according to the offer of the Austrian distributor of the AaS, queried in
May 2010), respectively. The Austrian distributor of the AaS has
currently a special offer for a test set including 5 flexible video
laryngoscopes and the monitor screen for about 990 Euro.
investment of the AaS is significantly lower than that of alternative
products. The benefits of the AaS are that it
eliminates time and costs of hygienic reprocessing associated with standard
flexible laryngoscopes, requiring a special automatic endoscopy
washing machine, and repair costs. In addition, the AaS eliminates any risks of cross infection and is always available
for use in other patients.
evaluated the AaS for orotracheal intubation in 10 patients with apparently
normal airways. Experienced endoscopists had regularly problems with fogging
of the camera system and the presence of secretions obscuring the view; this
is an inherent weekness of the AaS because the working channel cannot be
used for suctioning. Pujol and co-workers (1) encountered similar problems
with the use of the AaS in a case series of 10 patients with predicted
difficult intubation. We recommend that the manufacturer should redesign the
current model of the AaS and provide this device with a larger sized working
channel and the facility for suctioning.
