Anaesthesia

The light from a battery-powered laryngoscope with a fibreoptic blade is limited by the 3-V battery and deteriorates with use, as the optic fibres break. A laryngoscope handle is described in which the bulb is replaced by a fibreoptic cable connecting to a mains, halogen light source. ⋯ The fibre optic cable is attached at the side of the handle and does not interfere with intubation. The mains-powered light source has the advantages of being reliable with the ability to switch immediately to a second bulb; low running costs; improved light for intubation and it makes it possible to use a dental mirror for indirect laryngoscopy in difficult intubations.
