Rigid Intubation Scopes

Rigid endoscopes are very valuable tools for intubation in certain difficult scenarios, but are not commonly used in most centres.  The techniques and learning curve differ significantly from normal direct laryngoscopy, requiring independent practice to become proficient.  Pictured here are (left to right) a rigid bronchoscope, Bonfils, Levitan and Shikani optical stylets (rigid intubating endoscopes).

This is the set-up for basic training on an UCT Anaesthesia Airways course.  Which of these devices have you used?  Do you have tricks or comments to share?

Paediatric Bonfils Intubation

Video

Intubation in a young child with a severe submandibular abscess using the paediatric Bonfils rigid intubating endoscope under inhalational general anaesthesia. Direct laryngoscopy showed only severe swelling with a Cormack-Lehane grade 3b view.  A standard laryngoscope was used with the left hand to create an open path for the Bonfils just right of the midline, avoiding the worst of the submandibular swelling.  3.5mm Bonfils allowed intubation with a 4.5 mm uncuffed ETT.  Note that because this is a rigid intubating scope, it is not inserted through the vocal cords, but they are visible through the tube as it is inserted with the Bonfils held steady.

AirwayHowTo: Leak test a flexible endoscope

Video

Flexible fibreoptic and video endoscopes are fantastic but expensive pieces of equipment. In order to be maintained in top working condition, they need a little tender loving care. A particular problem occurs when the sheath of the scope becomes damaged or cracked, allowing fluid (especially corrosive cleaning solutions) to enter the inner workings of the scope, causing irreparable damage. The inner workings of the scope are a sealed environment. The patency of the seal – and thus the presence or absence of any damage – can easily be determined by performing a leak test. Although this is usually performed by medical technologists who are looking after the scopes, it can just as be performed quickly by the user while the scope is being prepared, or just before cleaning. Spend 100 seconds watching this brief, unadorned video which will walk you through the process. The demonstration here is using our Storz equipment, but is very similar regardless of the make or model of endoscope.
