BOTHELL, Wash., Nov. 29, 2012 /PRNewswire/ -- Verathon Inc., Bothell, Washington, is initiating a voluntary recall of GlideScope GVL Video Laryngoscopes reusable blades that were manufactured between December 2010 and August 2011. These laryngoscope blades have been found to be prone to developing cracks and/or breaking across the tip of the blade, which potentially could result in pieces of the blade breaking off in patient's mouths and obstructing the airway or being swallowed. (Logo: http://photos.prnewswire.com/prnh/20061011/SFW044LOGO) Healthcare facilities that have GlideScope GVL reusable blades that are being recalled should stop using the blades and contact Verathon Customer Care to obtain a replacement blade, if one has not already been provided. Customers should also contact Customer Care regarding any other questions about the recall. Customer Care can be reached at (800) 331-2313 (U.S. and Canada) or (425) 867-1348 (international), Monday through Friday from 6:00am to 5:00pm PST for the United States and 6:00am to 4:30pm PST outside of the United States. Customers may also email the company at firstname.lastname@example.org. The recall includes the following models within the specified serial number ranges: GlideScope GVL 3, 0574-0007: MD10500 to MD112387 GlideScope GVL 4, 0574-0001: LG105000 to LG112758 GlideScope GVL 5, 0574-0030: XL105000 to XL111798 The firm voluntarily recalled the products after learning about design characteristics leading to cracked and broken blades. FDA has been apprised of this action. The affected GlideScope GVL blades are at risk of developing stress cracks at the blade tip that may not be readily visible during routine inspection prior to intubation. This cracking may eventually cause the blade tip to break and the product to fail. To date, no patient injuries due to this issue have been reported to Verathon.
