Magill forceps come in small or large sizes. During tracheal intubation, they can be used to direct the tracheal tube towards the larynx and vocal cords. Care should be taken to protect the tracheal tube cuff from being damaged by the forceps. Other uses include the insertion and removal of throat packs and removal of foreign bodies in the Oropharynx and larynx.  Videolaryngoscopes Recent advances in miniaturized, high-resolution, digital camera and fiberoptic technology have led to a new generation of crossover devices. These videolaryngoscopes, offering indirect laryngoscopy, combine features of both the flexible fiberoptic scopes and the standard rigid laryngoscopes. The images are transmitted using fiberoptics or lenses and prisms with the light pathways encased in a rigid device. The cameras used offer wide views so allowing the user to see around corners, similar to the fibreoptic scopes. Certain designs have a channel that guides the tracheal tube into the trachea. Videolaryngoscopes improve the view of the glottis, as the camera eye is only centimeters away from the glottis. Some designs use direct viewing through an eyepiece or an attached or remote screen. Their use requires minimal neck movement and can make laryngoscopy and hopefully successful tracheal intubation easier. Such devices may well supersede the classic laryngoscopes.  Catheter mount This is the flexible link between the breathing system tubing and the tracheal tube, face mask, supraglottic airway device or tracheostomy tube. The length of the catheter mount varies from 45 to 170 mm. Components 1.A corrugated disposable plastic tubing. Some catheter mounts have a concertina design allowing their length to be adjusted. 2. The distal end is connected to either a 15-mm standard tracheal tube connector, usually in the shape of an angle piece, or a 22-mm mask fitting. 3. The proximal end has a 22-mm connector for attachment to the breathing system. 4. Some designs have a condenser humidifier built into them, 5. A gas sampling port is found in some designs. Mechanism of action 1. The mount minimizes the transmission of accidental movements of the breathing system to the tracheal tube, Repeated movements of the tracheal tube can cause injury to the tracheal mucosa. 2. Some designs allow for suction or the introduction of a fiberoptic bronchoscope. This is done via a special port. Problems in practice and safety features 1. The catheter mount contributes to the apparatus dead space. This is of particular importance in pediatric anesthesia. The concertina design allows adjustment of the dead space from 25 to 60 mL. 2. Foreign bodies can lodge inside the catheter mount causing an unnoticed blockage of the breathing system. To minimize this risk, the catheter mount should remain wrapped in its Sterile packaging until needed. Thank you
