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 AsA 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 AsA only in a single patient.      


The costs of the AsA 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 AsA, queried in May 2010), respectively; the Austrian distributor of the AsA has currently a special offer for a test set including 5 flexible video laryngoscopes and the monitor screen for about 990 Euro.


The start-up investment of the AsS is significantly lower than that of alternative products. The benefits of the AsA 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 AsA eliminates any risks of cross infection and is always available for use in other patients.


We evaluated the AsA 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 AsA because the working channel cannot be used for suctioning. We recommend that the manufacturer should redesign the current model of the AsA and provide this device with a larger sized working channel and the facility for suctioning.
