Through the 1970s and 1980s, many versions of a lighted stylet had been introduced, including the Fiberoptic Malleable Lighted Stylette (Metropolitan Medical Inc., Winchester, VA), Fiberoptic Lighted-Intubation Stylette (Anesthesia Medical Specialties, Santa Fe, CA), Lighted Intubation Stylet (Aaron Medical, St. Peterborough, FL), Flexilum™ (Concept Corporation, Clearwater, FL), Tubestat™ (Xomed, Jacksonville, FL) (Figure 11-5), and Imagica Fiberoptic Lighted Stylet (Fiberoptic Medical Products, Inc., Allentown, PA). Some of these devices have proven to be effective and safe in placing an ETT both orally and nasally.34-36 Even though favorable results have been reported with these devices, substantial limitations have been identified: (1) poor light intensity; (2) short length, limiting the use of the lightwand device to a short or cut ETT; (3) absence of a connector to secure the ETT to the lightwand device; (4) rigidity of the lightwand, hampering use of the devices with other techniques, such as light-guided nasal intubation; and (5) most lightwands were designed for single use, increasing the cost per intubation. For these reasons and others, intubation using a lightwand did not receive widespread popularity until the Trachlight™ (Laerdal Medical, Wappingers Falls, NY) device became available.
