The Vie Scope is used to insert a bougie or tracheal introducer under direct vision via straight line of sight between the vocal cords and into the trachea. The Vie Scope is not designed to pass an endotracheal tube directly through it.
The Vie Scope design is intentional as its current width allows an excellent direct view to the vocal cords but is narrow enough to negotiate past the mandible, maxilla and tongue. The steps involved in intubating a patient with a Vie Scope are as follows:
1. Insert Vie Scope using either hand directly to the vocal cords ie BELOW the epiglottis
2. Under direct vision using a straight line of sight pass a bougie between the vocal cords to the appropriate distance
3. Remove the Vie Scope keeping the bougie is the same position in the patient
4. Pass an endotracheal tube over the bougie into the trachea to the appropriate depth
5. Remove the bougie, confirm ventilation
